[U-Boot] boot.bin on SD Card for SAMA5D3 Xplained

[U-Boot] boot.bin on SD Card for SAMA5D3 Xplained

[Daniel Evans]

Trying to get uboot SPL boot.bin to run on an SD card for the sama5d3 xplained board.  All I get is RomBOOT and no other messages.  I have tried throwing in a couple test pins to toggle in board_early_init_f but still not getting any debug.  I can get at91bootstrap to produce a boot.bin that works on the sama5d3 xplained so I am assuming I don’t have a bad board.  My boot partition is FAT16.  To compile I just run the following on Debian Buster :

make mrproper
make sama5d3_xplained_mmc_defconfig
make

Cross Compiler is gcc-linaro-6.4.1-2018.05-x86_64_arm-linux-gnueabihf

When finished compiling I just copy the boot.bin to my BOOT partition.

Has to be something obvious that I am missing.  Any insight is appreciated…

Hello,

Check the datasheet for sama5d3 SoC section 11.4.3. - Valid code 
detection (my datasheet is dated 2 Feb 2016 if it helps)

Basically the vector 6 needs to have hardcoded the binary size. Are you 
doing that ? Otherwise the RomBOOT code will consider your binary as faulty.

PS. make sure endianess is right, use a good hexeditor...

Hope this helps,
Eugen

[U-Boot] boot.bin on SD Card for SAMA5D3 Xplained

[Daniel Evans]

Thanks,

That put me on the right path.  For some reason the nandheader is being added to the top of the boot.bin for the mmc/SD build.

$ ls -l boot.bin
-rw-r--r-- 1 nelson nelson 62686 Dec  5 12:25 boot.bin
$ hexdump boot.bin | head
0000000 2405 c090 2405 c090 2405 c090 2405 c090
*
00000d0 000f ea00 f014 e59f f014 e59f f014 e59f
00000e0 f014 e59f f40e 0000 f014 e59f f014 e59f
00000f0 0040 0030 0040 0030 0040 0030 0040 0030

0000120 001a e331 001f 13c0 0013 1380 00c0 e380
0000130 f000 e129 0f10 ee11 0a02 e3c0 0f10 ee01
0000140 0078 e59f 0f10 ee0c 0006 eb00 001a eb00

So I just removed it and then you can see the size is correct once removed (0x0000F40E):

$ dd bs=208 skip=1 if=boot.bin of=bootShort.bin
$ hexdump bootShort.bin | head
0000000 000f ea00 f014 e59f f014 e59f f014 e59f

0000020 0040 0030 0040 0030 0040 0030 0040 0030
0000030 0040 0030 0040 0030 0040 0030 beef dead
0000040 fffe eaff 002a ea00 0000 e10f 101f e200
0000050 001a e331 001f 13c0 0013 1380 00c0 e380
0000060 f000 e129 0f10 ee11 0a02 e3c0 0f10 ee01
0000070 0078 e59f 0f10 ee0c 0006 eb00 001a eb00
0000080 01b6 eb00 0f15 ee07 0f9a ee07 0f95 ee07
0000090 ff1e e12f ffeb eaff 0000 e3a0 0f17 ee08
$ ls -l bootShort.bin
-rw-r--r-- 1 nelson nelson 62478 Dec  5 12:54 bootShort.bin

Any insight into why that is being added at the beginning?  Is there a configuration that needs tweaking or to be removed?

Okay, just finished my git bisect, this turned out to be a miss-placed

Interesting find, is this wrongly done for all the boards in the commit 
or just sama5d3_xplained ?

Feel free to submit a patch if this fixes the issue, and we will review it.

Thanks !

Would this be an acceptable alternative?

It guards the modification of 'boot.bin'@the build location. Also, as
Kconfig items are cleaned-up, the guard will still hold.

I can submit a proper patch, if this is reasonable.

[U-Boot] [PATCH] ARM: at91: Fix 'boot.bin' generation when CONFIG_SD_BOOT is enabled

[Derald D. Woods]

On AT91 platforms configured for SD_BOOT, this commit avoids the
generation of the PMECC header used for booting from NAND flash. This
issue was found by attempting to boot the SAMA5D3-XPLD board with the
'sama5d3_xplained_mmc_defconfig'.

Hi Derald,

Thanks for your patch, however, I don't like that we do not use the 
CONFIG_SPL_GENERATE_ATMEL_PMECC_HEADER anymore... isn't this config 
supposed to say whether we are going to generate the header or not ?

Checking if "not sd-boot" doesn't look like a good option... we may use 
SPI boot or QSPI or some other type at some point and the issue will 
still be there.

I would rather fix the original patch by Wenyou, namely move the #ifdef 
below to not have the GENERATE_ATMEL_PMECC enabled for SDBOOT.

Does this sound good for you?

Thanks again,

Eugen

That is not what is happening with this patch. SPL_GENERATE_ATMEL_PMECC_HEADER
is not removed. The config still serves its orignal intent. If SD_BOOT
is configured, then NAND is not being used. In this non-NAND case, the
header is not needed.

This location and method would work for those nod-NAND cases also. See
below.

If this SPL_GENERATE_ATMEL_PMECC_HEADER only needs to be there for NAND,
why not guard the 'ifdef ($(CONFIG_NAND_BOOT,y))'? Would this be better?
Basically we could replace the 'ifneq ($(CONFIG_SD_BOOT),y)' with the
more appropriate 'ifeq ($(CONFIG_NAND_BOOT),y)'. This would actually
allow the future use-cases to be added as they become available and can
be shown to actually boot with the header applied.

I will put together a proper version 2 of my patch later today.

This would allow other configurations to 'opt-in' to applying the

Also, the SPL_GENERATE_ATMEL_PMECC_HEADER needs transitioning to
Kconfig. Having the logic in "Makefile.spl" would help with that work
too.

My questions are :

If we have configured CONFIG_SPL_GENERATE_ATMEL_PMECC_HEADER, then why 
the header is not being applied after your patch ?

And why do we configure CONFIG_SPL_GENERATE_ATMEL_PMECC_HEADER if we do 
not wish the PMECC header in the image ?

With your patch, why do we generate the PMECC header w.r.t. the 
configuration of NAND_BOOT and not CONFIG_SPL_GENERATE_ATMEL_PMECC_HEADER ?

Or perhaps I am missing something on the purpose of 
CONFIG_SPL_GENERATE_ATMEL_PMECC_HEADER ?

To quote from doc/README.atmel_pmecc :
<quote>
To enable the generation of atmel PMECC header for SPL one need to 
define
CONFIG_SPL_GENERATE_ATMEL_PMECC_HEADER. The required parameters are 
taken from
board configuration and compiled into the host tools atmel_pmecc_params. 
This
tool will be called in build process to parametrize mkimage for 
atmelimage
type. The mkimage tool has intentionally _not_ compiled in those parameters.
</quote>


So I would expect CONFIG_SPL_GENERATE_ATMEL_PMECC_HEADER to generate the 
PMECC header if configured, and if this flag is not present, the PMECC 
header is not generated.
I do expect that SD card booting configurations do not select this flag.

The patch does _not_ remove CONFIG_SPL_GENERATE_ATMEL_PMECC_HEADER or change
its purpose or overall role. Literally. It is a very simple patch that
solves
a "no-boot" issue for at least sama5d3-xpld. I read the documents before
my patch. This is a post-build tooling issue. Makefile.spl can leverage
configs as they are naturally selected.

I am simply working on a proper solution. I have the SAMA5D3-XPLD board
and use it occasionally. The original post to the mailing list simply
peaked my interest. I had the board pinned at v2017.09 in my personal
build environment for the same issue. I am just digging deeper this time
around.

I began looking into converting the following to Kconfig:

[scripts/config_whitelist.txt] (REMOVING ITEMS)
------------------------------------------------------------------------
CONFIG_ATMEL_NAND_HWECC
CONFIG_ATMEL_NAND_HW_PMECC
CONFIG_PMECC_CAP
CONFIG_PMECC_SECTOR_SIZE
CONFIG_SPL_GENERATE_ATMEL_PMECC_HEADER
------------------------------------------------------------------------

[arch/arm/mach-at91/Kconfig]
------------------------------------------------------------------------
config ATMEL_NAND_HWECC
	bool "Atmel Hardware ECC"
	default n

config ATMEL_NAND_HW_PMECC
	bool "Atmel Programmable Multibit ECC (PMECC)"
	select ATMEL_NAND_HWECC
	default n
	help
	  The Programmable Multibit ECC (PMECC) controller is a programmable
	  binary BCH(Bose, Chaudhuri and Hocquenghem) encoder and decoder.

config PMECC_CAP
	int "PMECC Correctable ECC Bits"
	depends on ATMEL_NAND_HW_PMECC
	default 2
	help
	  Correctable ECC bits, can be 2, 4, 8, 12, and 24.

config PMECC_SECTOR_SIZE
	int "PMECC Sector Size"
	depends on ATMEL_NAND_HW_PMECC
	default 512
	help
	  Sector size, in bytes, can be 512 or 1024.

config SPL_GENERATE_ATMEL_PMECC_HEADER
	bool "Atmel PMECC Header Generation"
	select ATMEL_NAND_HWECC
	select ATMEL_NAND_HW_PMECC
	default n
	help
	  Generate Programmable Multibit ECC (PMECC) header for SPL image.

------------------------------------------------------------------------

The issue is that the PMECC configuration items are used along with
other NAND configuration items outside of a NAND_BOOT scenario. I would
like to get the proper Kconfig selections up and running. This is just a
start. I will not have any more time until this weekend. I will send
another patch at that time.

Cheers,

Derald

[U-Boot] [PATCH] ARM: at91: Convert SPL_GENERATE_ATMEL_PMECC_HEADER to Kconfig

Sorry for the late response. Family and day job take priority.

The patch is the simplest technical conversion that I could produce with my
board (SAMA5D3-XPLD) as the test platform. I was very careful not to touch
anything unrelated. It is not intended to address permutations outside of
the PMECC Kconfig scope. I have submitted these type of conversions to
U-Boot in the past. Adding speculative things is risky when you only have
one development board. The patch works well, for me, and addresses the
original need. All items, in the patch, are currently in scope. If there
are additions and/or modifications, feel free to modify the patch. It is
complete from my perspective. I do not have any additional time to chase
this any further. I have been developing for some time now and can handle
an 'out of tree' patch, in my environment, until something better comes
along. This patch is just my contribution to the process.

Cheers,

Derald

Hello Derald,

 From my point of view the PMECC header generation for SPL should be 
done if and only if the SPL is being placed in NAND flash namely 
defconfigs having *nandflash* in the name.

Thus I disagree with enabling it on spiflash configurations (like you 
did for the *mmc* configurations looks OK)

If you have any reasons or arguments , or anyone else does, please 
correct me.

If you do not have time to change the patch, that is OK, I can take over 
at some point when I have the time or someone else can pick and rework a 
little bit on that specific point and make a v2.

Thanks again,

Eugen

The patch is about 'one' thing. Kconfig conversion. Things that you are

does its job in a provable manner with changing existing usage.

Ok, I understand your point.
Can you make the CONFIG_SPL_GENERATE_ATMEL_PMECC_HEADER depend on 
NAND_BOOT though ? This way the errors cannot happen again.

Also the other defconfigs need to depend on NAND if they are strict NAND 
related.

Maybe we can get more opinions from someone more familiar with the NAND 
subsystem ? Adding Miquel and Boris.

Thanks,

Eugen

I agree.

But are the existing configs that enable both SPL_GENERATE_ATMEL_PMECC_HEADER
and SPI_BOOT really valid?

It would appear that those entries may just be placeholders in the event
that an end-user enabled PMECC and NAND_BOOT for that particular board.

I could rework the patch to remove PMECC items from non-NAND_BOOT
configs. Comments could be used to preserve previous values. Does this sound
reasonable?

Additionally, I would make ATMEL_NAND_HW_PMECC dependent on ATMEL_NAND_HWECC
as it should be.

I can only test on the SAMA5D3-XPLD board.

[U-Boot] [PATCH 1/2] nand: atmel: Replace SYS_NAND_ECC_BASE with ATMEL_BASE_ECC

[Derald D. Woods]

This commit removes remaining uses of SYS_NAND_ECC_BASE. Including
"<asm/arch/hardware.h>" in "drivers/mtd/nand/raw/atmel_nand.c" provides
access to ATMEL_BASE_ECC.

[U-Boot] [PATCH 2/2] ARM: at91: Convert SPL_GENERATE_ATMEL_PMECC_HEADER to Kconfig

[Derald D. Woods]

This commit converts the following items to Kconfig:

CONFIG_ATMEL_NAND_HWECC
CONFIG_ATMEL_NAND_HW_PMECC
CONFIG_PMECC_CAP
CONFIG_PMECC_SECTOR_SIZE
CONFIG_SPL_GENERATE_ATMEL_PMECC_HEADER

Config files not explicitly containing the name *nandflash* will have
PMECC disabled. PMECC support requires that a header be applied to
"boot.bin". The generated PMECC "boot.bin" is intended for NAND media.

- Make ATMEL_NAND_HW_PMECC dependent on ATMEL_NAND_HWECC
- Make SPL_GENERATE_ATMEL_PMECC_HEADER dependent on NAND_BOOT
- Remove PMECC from non-NAND_BOOT configs

OK.  So this is likely due to patch 0001 only. I will drop it. And try a
few of these configs.

[U-Boot] [PATCH v3 1/1] ARM: at91: Convert SPL_GENERATE_ATMEL_PMECC_HEADER to Kconfig

[Derald D. Woods]

This commit converts the following items to Kconfig:

CONFIG_ATMEL_NAND_HWECC
CONFIG_ATMEL_NAND_HW_PMECC
CONFIG_PMECC_CAP
CONFIG_PMECC_SECTOR_SIZE
CONFIG_SPL_GENERATE_ATMEL_PMECC_HEADER

Config files not explicitly containing the name *nandflash* will have
PMECC disabled. PMECC support requires that a header be applied to
"boot.bin". The generated PMECC "boot.bin" is intended for NAND media.

So, this too has a bunch of problems:

v1 was actually pretty close to size neutral and nothing failed to
build.  I'm going to build that again and tweak it for neutrality.
Thanks again!

Sounds good to me. Sometimes you have to stick with your first thoughts.
The simple change is usually the best case.

Note that to make this more size neutral I had to tweak a few configs
and I hope I didn't inadvertently re-break some platforms.  However,
with them in Kconfig now a re-adjustment and removal of drivers that
shouldn't be there for a specific defconfig is easier, sorry about the
potential noise!

Also, I see but couldn't quite track down which option wasn't quite
right on sama5d2_ptc_ek_mmc and sama5d2_ptc_ek_nandflash as we're seeing
some size reduction in atmel_nand_chip_init() but non-obvious to me
which option is/isn't set and I re-checked the migration.

Applied to u-boot/master, thanks!
