Hi,


   I'm using a SinA33 dev board (Allwinner a33 SoC) and at the moment I'm
trying to boot from the eMMC.

But it fails in the following way:


*Got the following error at boot time:*
*U-Boot SPL 2016.09-rc2-00125-g6e8b42f (Sep 08 2016 - 11:00:46) DRAM: 1024
MiB Trying to boot from MMC2 MMC Device 1 not found spl: could not find mmc
device. error: -19 SPL: failed to boot from all boot devices ### ERROR ###
Please RESET the board ###*


More info in the linux-sunxi mailing thread:

https://groups.google.com/forum/#!topic/linux-sunxi/U4t-0VcDxLU?


Thanks

So I've been on the same issue for the last couple of days.

Since that board is already supported, adding support for the eMMC
basically came down to that patch on top of 2016.09-rc2.

http://code.bulix.org/kcgxri-106037?raw

(Quite hackish, the 8-Bits part being a separate issue that would need
to be addressed somehow).

However, it doesn't work, neither when flashing u-boot on the eMMC
itself (where there's a timeout error in the SPL) nor when trying to
access the eMMC from a U-Boot loaded from the (external) SD.

In the latter case, even mmc dev 1 fails silently.

I traced that down to the mmc_switch here:
http://git.denx.de/?p=u-boot.git;a=blob;f=drivers/mmc/mmc.c#l530

Which fails with ETIMEDOUT, and more specifically, it's the call to
mmc_rint_wait here
http://git.denx.de/?p=u-boot.git;a=blob;f=drivers/mmc/sunxi_mmc.c#l383
that times out.

Increasing the timeout value (to 10000) doesn't really change
anything. I guess this is also the reason why we had a timeout error
in the SPL.

This eMMC works fine in Linux, with the same muxing (and I guess the
earlier commands wouldn't be successful if the muxing or power was not
set up appropriately). So I'm kind of running out of ideas on what
could be the root cause of this.

Hans, any ideas?

Thanks,
Maxime

Maybe the emmc needs external pull-ups ? I don't remember if u-boot
always enables those or not ...

I've not tried booting from eMMC on A33 boards (-ENOHARDWARE) but it
does work on A13 and A20 boards (last time I tried).

Hans

So I pushed this a bit more, and it seems like commenting the call to
mmc_change_freq makes everything just work.

Reading the JEDEC spec, it looks like when you switch to high speed,
you also need to change the controller clock rate, that u-boot doesn't
seem to do at the moment, which obviously will fail, since the
controller will be stuck at the former rate, while the eMMC would be
switched.

If I comment mmc_change_freq, everything works.

I'm guessing this is more about what rates and modes are supported,
rather than the actual SoC.

Hmm, I'm pretty sure the u-boot sunxi mmc code
does properly change the clock, see mmc_set_mod_clk() in
drivers/mmc/sunxi_mmc.c

This will switch to the right PLL, etc. So there likely is
something else going on making things not work at higher
speeds. Maybe we need a higher driver strenghts at the
mmc io pins, or maybe we've a completely unrelated issue ?

I'm pretty sure that the eMMC's on A20 devices work fine
in 50MHZ (SDR) mode.

Regards,

Hans

Yeah, sorry, I was missing the mmc_set_clock call in that function,
that ends up calling mmc_set_mod_clk.

I'll look more into it, it might be just a matter of phases to adjust.

Yep, I noticed that. However, what confuses me more is that the
command seems to be sent here:
http://git.denx.de/?p=u-boot.git;a=blob;f=drivers/mmc/mmc.c#l530

And set_ios is being called after we check that everything
works. Linux for example calls set_ios right after switching

I've tested that already. It doesn't change the outcome.

What emmc was that? Did it support HS? Was it considered an SD (and
went through sd_change_freq), or an MMC?

Here is what "mmc info" in u-boot says on my UTOO P66 tablet (A13)
with 4G eMMC (manually transcribed, no serial console):

Device: SUNXI SD/MMC
Manufacturer ID: 70
OEM: 100
Name: MMC04
Tran Speed: 52000000
Rd Block Len: 512
MMC version 4.4.1
High Capacity: Yes
Bus-width: 4-bit
<bunch of sizes>

And here is /sys/kernel/debug/mmc1/ios under linux:

clock:          52000000 Hz
vdd:            21 (3.3 ~ 3.4 V)
bus mode:       2 (push-pull)
chip select:    0 (don't care)
power mode:     2 (on)
bus width:      3 (8 bits)
timing spec:    1 (mmc high-speed)
signal voltage: 0 (3.30 V)
driver type:    0 (driver type B)

timeout_msecs is expired or hit SUNXI_MMC_RINT_INTERRUPT_ERROR_BIT?
If hit ERROR_BIT, did you check which bit is set?

If error is occurred when mmc_change_freq() is running, cid/ext_csd register have already read.
It means the controller read the something from eMMC card.

If then..i guess that it's possible to set the initial clock as higher clock than 400KHz.
Did you check this?

I haven't check, I'll look (next week though, I'm at a conference and
away from that board).

It really is the next command right after the switch that fails, it
really feels like that switch changes the timings of the card without
changing the one from the host.

I'll try. But wouldn't that introduce some compatibility issues of its
own?

So I've been able to test this, and we indeed not hit the timeout but
the error bit is set, with 0x40.

Hi,

I have tried it, no success

In my case, i am sure, that problem not in emmc card.
First MMC_CMD_SWITCH in mmc_change_func works well without patches, but get stuck in second, when change bus width.

I have two almost similar socs, Allwinner A13(sun5i) and A20(sun7i).
They uses same sunxi_mmc.c driver. A13 boots well with master branch, but A20 only with my patch.

Below link shows diff in boot logs, A20 CONFIG_MACH_SUN7I on left, and A13 CONFIG_MACH_SUN5I on right side. A13 works well
https://www.diffchecker.com/XrmlaZfH <https://www.diffchecker.com/XrmlaZfH>

Using logic analyzer, i analyzed all command and all responses. 
Diagrams absolutely the same, from u-boot spl start, on both socs, until mmc_rint_wait return error.

https://dl.dropboxusercontent.com/u/10252748/A20vsA13.png <https://dl.dropboxusercontent.com/u/10252748/A20vsA13.png>
https://dl.dropboxusercontent.com/u/10252748/A20vsA13_ZOMMED.png <https://dl.dropboxusercontent.com/u/10252748/A20vsA13_ZOMMED.png>

at first look, looks like emmc not respond to A20, but if zoom more, 
https://www.dropbox.com/s/80u232i7wod93gf/A20.png?dl=0 <https://www.dropbox.com/s/80u232i7wod93gf/A20.png?dl=0>
we see, that no clocks in some time. If take A13 diagram, no empty clocks!
I have no jtag to debug more. I am not sure, but i think, for some reason, this empty clocks cause card fail.

So, only with this patch, Allwinner A20 soc can boot from emmc https://www.dropbox.com/s/0lfe2xifzbdbokb/emmcFix.patch?dl=0 <https://www.dropbox.com/s/0lfe2xifzbdbokb/emmcFix.patch?dl=0>

To exclude board factor, i get another board, Cubieboard2, desolder nand chip and put emmc on sdc2 lines.
Boot kernel from sd on sdc0 lines, kernel init emmc well, in 4 bit mode

So, some trouble in u-boot is exist, PLEASE HELP! 
U-Boot SPL 2016.11-rc1-g4dc34be

My board - A20:

U-Boot with my config
EMMC on sdc0 lines
	
U-Boot output:

MarsBoard - A20:

U-Boot with my config and mmc extra slot config set to 2

I have put external pullups on marsboard, boot from sd. Linux kernel init emmc fine, 4-bit width bus, so board works well

Hit any key to stop autoboot:  2 ... 0

SUNXI SD/MMC: 1
=> mmc dev 0
switch to partitions #0, OK
mmc0 is current device

emmc burned with same image as sd card, with mbr. rootfs, etc..
linux booted from sd card, well works with emmc partitions

Some summary

Marsboard by default has nand flash chip on sdc2 lines, but under nand chip, there is emmc bga pads also. 
So i have desoldered nand, and put emmc chip on it. Maybe there is no required pull ups on data lines to work on 4-bit widh, 
and when i boot kernel from sdc0 sd card, kernel init sdc2 emmc only in 1-bit mode. but it works well, i can read can and write, get mbr, etc..
I build u-boot with mmc extra slot config and burn it on emmc, and when i try to boot without sd, directly from emmc, got same errors as on by board.
When i boot to u-boot, it shows mmc1 mmc2, and mmc info works on both. But it cant read data and even mmc part not working.


My board has only sdc0 lines routed from soc. If solder emmc on it, not works, if sd card via wires, all ok, 4-bit width.

 Seems u-boot tries bus_width: 1, clock: 52000000, like linux kernel, but fails.

1. power supply is 3.3v on vcc and vccio
2 & 4. datasheet on eemc says

 Data bus width : 1bit (Default) , 4bit and 8bit
 MMC I/F Clock Frequency : 0 ~ 52MHz 
 MMC I/F Boot Frequency : 0 ~ 52MHz

 3. GPIO seems are correct, because then i solder sd card via wires on emmc pads, its boots correct

Just add the debug() into your driver..then it's only displayed your driver debug message.

#define debug() ...

Well, it's not normal.
It's possible to use only 1bit buswidth...but i didn't see the case about using only 1bit buswidth.

buswidth test are all failed..so it's set to 1bit buswidth..Dose it support 4bit buswidth on hardware?
If my understanding is right, it's used SDR20(?)..how about controlling clk value..?
clock value is set to high value..

When i bring up the eMMC/SD/SDIO..I did to check the below sequence.

1. Power is supplied correctly.
2. Clock is enabled correctly
3. GPIO pin is set to correct value. (Function, GPIO value..)
4. Which buswidth/busmode is supported..and it's correctly changed.

Above checking lists nave to ensure...after that..can be checked mmc core or host controller.

Beset Regards,
Jaehoon Chung

I decided to check how linux kernel init emmc on marsboard, which i boot from SD card
And i found, that it inited only in 1-bit mode, is it normal? it works, i can edit files on it

linux set 
eMMC(sdc2) to mmc0 
SD(sdc0) to mmc1

chip select:    0 (don't care)
power mode:     2 (on)
bus width:      0 (1 bits)

When i define CONFIG_DEGUB, u-boot binary size is to large for a20 sram
I have tried to disable unused features in config, but its not enough

I am not never set 8 bit mode
And now found it defines

#define MMC_MODE_4BIT		(1 << 2)
#define MMC_MODE_8BIT		(1 << 3)

and replace with 

#define MMC_MODE_4BIT		(1 << 2)
#define MMC_MODE_8BIT		(1 << 2) //(1 << 3)

The same result.

Maybe at here..switch to buswidth..but failed.
define debug() in your mmc driver..or enable CONFIG_DEBUG..then you can see all debug message.

Yes

Now i have checked det pin on my board. I use standart A20-OLinuXino-Lime_defconfig with my board.
So PH1 is pull-fown. No changes if just remove det pin

U-Boot SPL 2016.11-rc1-g4dc34be-dirty (Oct 12 2016 - 18:12:37)
DRAM: 512 MiB
Failed to set core voltage! Can't set CPU frequency
Trying to boot from MMC1
mmc_bread: Failed to read blocks
mmc_load_image_raw_sector: mmc block read error
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###



Then , i removed det pin from config and build again. Burn it to emmc(sdc2) on marsboard and tried to boot this board with mainline u-boot, not 2014 as before and get this.

U-Boot SPL 2016.11-rc1-g4dc34be-dirty (Oct 12 2016 - 18:24:58)
DRAM: 1024 MiB
CPU: 912000000Hz, AXI/AHB/APB: 3/2/2
Trying to boot from MMC2
MMC Device 1 not found
spl: could not find mmc device. error: -19
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###

Something new, error code is 19 ) Looks like it see that no card on sdc0 and found emmc on sdc2, but fails.
Same code on my board never tries mmc2, so it part works

> I will try to check codes relevant to sunxi..

I hope on your help, thank you very much

I understood more clearly...Your target for using is sdc0(eMMC), right?
- marsboard for just testing is sdc0 (SD-card)..

If det-pin problem, it should be fixed too easy. :)
I will try to check codes relevant to sunxi..

Sorry for helping more clearly..

  To: u-boot

On marsboard today i used 2014 u-boot, sd card on sdc0 hardware lines and emmc on sdc2 hardware lines.
and get error "Card did not respond to voltage select!? , then i tried to boot without sd card, only with emmc on sdc2

On my board i used mainline u-boot, emmc on sdc0 hardware lines.
And get block read error, logs below.

Brom on A20 chip firstly tries sdc0, if fail, then sdc2.

I dont checked only gpio pins, maybe in det pin problem, i will try, thx.

If i misunderstood something, let me know, plz. :)
(Because i don't have targets relevant to sunxi..)

U-Boot SPL 2014.04-10685-g4af825f-dirty (Jun 14 2014 - 17:55:48)
-> This is right? 2014?

What did you mean sdc0/sdc1/sdc2...do you mean the hardware line?
If it's hardware line..sdc0 is for eMMC?

"Card did not respond to voltage select!"
1. There is no card on slot..
2. Power doesn't supply..

Did you check everything? Power, clock, gpio pin..

But then i tried my board with mainline u-boot, emmc was on sdc0 lines.

Now i tried, boot marsboard from sd, hit button to stop kernel loading.
sun7i# mmc list
SUNXI SD/MMC: 0

Looks like its doesnt see emmc on sdc2.

This log means that there is no card on slot..
In my case..when i set the wrong mmc boot dev in environment, I had seen the similar log.
Could you share the environment values?

I'm not sure...100% working card...because we don't ensure 100% what problem there are in mainline u-boot.

It's strange.

  To: u-boot

In order to exclude possible errors on my board, i get MarsBoard A20 Lite, desolder nand, and put on emmc pads my emmc flash.
So emmc is on sdc2 lines. When iam booting from sd on sdc1, linux kernel can init emmc, and i got /dev/mmcblkp1, works well.
But when i eject sd and try to boot from sdc2 emmc, get the same err 17. 
In this case i have used some old uboot from marsboard site, because mainline u-boot have not config for a20 marsboard.

U-Boot SPL 2014.04-10685-g4af825f-dirty (Jun 14 2014 - 17:55:48)
Board: MarsBoard-A20 & MarsPI
DRAM: 1024 MiB
CPU: 960000000Hz, AXI/AHB/APB: 3/2/2
Card did not respond to voltage select!
spl: mmc init failed: err - -17
### ERROR ### Please RESET the board ###

So, the problem with eMMC KLM4G1FE3B-B001 is exists(
Maybe you know some cheap emmc, which is 100% works with mainline u-boot?

Hi!
Very appreciate your help! Hope we will fix it, because my board will be garbage without emmc (
So, my steps:

git clone git://git.denx.de/u-boot.git --depth 1; cd u-boot;
make CROSS_COMPILE=arm-linux-gnueabihf- A20-OLinuXino-Lime_defconfig
make CROSS_COMPILE=arm-linux-gnueabihf-

Also turn on CONFIG_MMC_TRACE

After run, got:

Well, i needs to get more information..If you guess that seems to return 0 from block_read()..
then you can find which condition was hit..is it impossible?

If you can share more debug message..then i will help you.

Emmc Card was the new one, so i just burn a dump of working sd. Previously
sd have been wired to board for test.

Board is a custom,  like olinuxino lime which with nand and sd slot, 512 mb
ram. So i using it defconfig and in case of sd card, it works.
Emmc lines has external pullups according to the datasheet.

Like a sd card. I have emmc to sd adapter, so

dd if=u-boot-sunxi-with-spl.bin of=/dev/sdb bs=1024 seek=8

and then just solder emmc to my board.

Need few more info, how exactly you wrote SPL on emmc, could you provide
that.

Hi!

I am trying to boot my A20 board from eMMC KLM4G1FE3B-B001, but has no success. 
Commenting mmc_change_freq has no effect. 
U-Boot 2016.03 just says Could not determine boot source

I have found, that it stucks in sunxi_mmc_has_egon_boot_signature. 

int sunxi_mmc_has_egon_boot_signature(struct mmc *mmc)
{
	char *buf = malloc(512);
	int valid_signature = 0;

	if (buf == NULL)
		panic("Failed to allocate memory\n");

	if (mmc_getcd(mmc) && mmc_init(mmc) == 0 &&
	    mmc->block_dev.block_read(&mmc->block_dev, 16, 1, buf) == 1 &&
	    strncmp(&buf[4], "eGON.BT0", 8) == 0)
		valid_signature = 1;

	free(buf);
	return valid_signature;
}

mmc_init(mmc) return no errors, seems good, but
block_read returns 0, seems it cant read emmc.
