Dear list,
I have an i.MX35PDK (mx35_3stack) with one U-Boot running within the NAND flash and one U-Boot running within the parallel NOR flash.
I am now trying to get another one running in a serial NOR flash (S25FL064K) I soldered to the CSPI1 lines with CSPI1_SS1 as chip select line.
Then I changed the bootstrap switches as follows:
BOOT_MODE[1:0]: 00 Internal boot
BT_MEM_CTL[1:0]: 11 Expansion device (... , serial ROM)
BT_BUS_WIDTH: 1 3-byte address SPI device (serial Flash)
BT_MEM_TYPE[1:0] 11 Serial ROM via SPI
According to my oscilloscope (SPI decoder included), the hardware setup behaves as it should do. The processor clocks, it activates the SS1 line,
it sends read commands (0x03) following an address and the serial flash sends answers with bytes matching the u-boot.bin file.
I tried the following to build the u-boot binary:
1. $ make mx35pdk
Then I burned u-boot.bin to the serial flash starting at address 0x00
2. See 1. but burning the u-boot.bin file to the serial flash starting at address 0x400 (doc/README.imximage)
3. $ make mx35pdk
$ cp board/freescale/mx51evk/imximage.cfg board/freescale/mx35pdk/
$ ./tools/mkimage -n ./board/freescale/mx35pdk/imximage.cfg -T imximage -e 0xA0000000 -d u-boot.bin u-boot.imx
Then I burned u-boot.imx to the serial flash starting at address 0x00
4. See 3. but burning the u-boot.imx file to the serial flash starting at address 0x400 (doc/README.imximage)
As you might guess, none of the above attempts works. I get no serial output from U-Boot.
Has anyone a short description how to compile U-Boot in order to run from serial NOR flash?
Thank you very much in advance.
With best regards
Michael Hornung

This is not correct. You can not use the DDR settings from mx51evk
directly into mx35pdk.
You would need to create a imximage.cfg for mx35pdk.
Take a look at Freescale U-boot as a reference:
http://opensource.freescale.com/git?p=imx/uboot-imx.git;a=blob;f=board/freescale/mx35_3stack/flash_header.S;h=b662669f80061be18787eafea6eb3668786b6224;hb=329240314138de1fb8d3d08531e0c3408482972f
With these values you can create a correct imximage.cfg file for mx35pdk.
Currently mx35pdk does not support internal boot mode and that is the
reason you don't find a imximage currently.
So my suggestion for you is to try to boot from internal boot mode
first. Try booting from SD card first as this would be easier.
Once you managed to boot from SD card, you will be also able to boot
it from SPI NOR.

Just to clarify: this file has the RAM settings for two versions of
the board. Earlier mx35pdk came with mDDR and the more recent boards
have DDR2. Most likely your mx35pdk has DDR2 populated, do the values
you need to use are:
//DDR2 init
DCDGEN(2, 4, 0xB8001010, 0x00000304)
DCDGEN(3, 4, 0xB8001010, 0x0000030C)
DCDGEN(4, 4, 0xB8001004, 0x007ffc3f)
DCDGEN(5, 4, 0xB8001000, 0x92220000)
DCDGEN(6, 4, 0x80000400, 0x12345678)
DCDGEN(7, 4, 0xB8001000, 0xA2220000)
DCDGEN(8, 4, 0x80000000, 0x87654321)
DCDGEN(9, 4, 0x80000000, 0x87654321)
DCDGEN(10, 4, 0xB8001000, 0xB2220000)
DCDGEN(11, 1, 0x80000233, 0xda)
DCDGEN(12, 1, 0x82000780, 0xda)
DCDGEN(13, 1, 0x82000400, 0xda)
DCDGEN(14, 4, 0xB8001000, 0x82226080)
DCDGEN(15, 4, 0xB8001004, 0x007ffc3f)
DCDGEN(16, 4, 0xB800100C, 0x007ffc3f)
DCDGEN(17, 4, 0xB8001010, 0x00000304)
DCDGEN(18, 4, 0xB8001008, 0x00002000)
You just need to convert these values into the proper syntax for imximage.cfg.

The best way to generate 'u-boot.imx' is to simply do 'make
u-boot.imx' and then you don't need to pass the above line manually.

In internal mode you should do:
#define CONFIG_LOADADDR 0x80800000
#define CONFIG_SYS_TEXT_BASE 0x87800000
for mx35.
You probably will need to skip the RAM init in
board/freescale/mx35pdk/lowlevel_init.S
For a quick test I would remove the call to 'setup_sdram' there,
because RAM will be inited by the values from your created
imximage.cfg file.
After you managed to boot from internal mode, then we can think on how
to properly handle both internal and external boot modes. Maybe we
will need to create another mx35pdk target so that we can handle the
internal mode.

Well, I don't have SPI NOR populated on my board ;-)
Besides that, flashing an SD card is much simpler. Please read
doc/README.imximage
Booting from SD is the mode we support by default on other
mx25/mx51/mx53/mx6 boards.

Please see the Freescale U-boot, you missed the initialization of the CS5:

Most likely it is because it will try to access the network, but you
missed to setup the CS5 as per the Freescale U-boot init sequence.

Sorry for that, I really missed it. So here what I did:

+BOOT_FROM sd
According to your advise I burned the image to a SD card and changed
BT_MEM_TYPE[1:0] to 00 (SD, MMC, eMMC, or eSD). You are so right, flashing
a SD card is a lot easier.
Then compiled a debugging version of U-Boot:
tools/mkimage -n "board/freescale/mx35pdk/imximage.cfg" -T imximage \
-e 0x87800000 -d u-boot.bin u-boot.imx

and here is the visible ouput to the serial line:

After some trial and error I came up with the follwing:

After those changes, U-Boot is going a little further:

Maybe you have another idea what to do next?
By the way: Do you use a BDI3000 for debugging and if so, could you please
send your board configuration file (.cfg) and your register definitions (.def).

Hmmm... it doesn't sound like a good idea to remove such lines.
Have you had any progress on this?
I am back to the office and can try to help you on this.

Unfortunately I had no time to look into the matter any further, but
I'll try again this week.

Hi Fabio,

I had some progress on my issue, here a summary of what I did:
- I configured a SD-Card as described in doc/README.imximage
- I did the following changes to the U-Boot sources:
+++ b/board/freescale/mx35pdk/imximage.cfg

This ended up as described earlier, with an U-Boot promp stoppping
with the following output:
> CPU: Freescale i.MX35 rev 2.1 at 532 MHz.
> Reset cause: POR
> I2C: ready
Then I did the following change:
+++ b/board/freescale/mx35pdk/mx35pdk.c
size1 = get_ram_size((void *)PHYS_SDRAM_1, PHYS_SDRAM_1_SIZE);
- size2 = get_ram_size((void *)PHYS_SDRAM_2, PHYS_SDRAM_2_SIZE);
+ size2 = 0;
+ /*size2 = get_ram_size((void *)PHYS_SDRAM_2, PHYS_SDRAM_2_SIZE);*/
gd->ram_size = size1 + size2;
And here the result:
U-Boot 2012.07-00024-g181e4a3 (Aug 02 2012 - 09:49:35)

Can you please try to remove #define CONFIG_ENV_IS_IN_FLASH and insert:
#define CONFIG_SYS_NO_FLASH
#define CONFIG_ENV_OFFSET (6 * 64 * 1024)
#define CONFIG_ENV_SIZE (8 * 1024)
#define CONFIG_ENV_IS_IN_MMC
#define CONFIG_SYS_MMC_ENV_DEV
Cced Stefano in case he has any suggestions.

At this point, there is no difference for u-boot starting the kernel if
it has booted in external or internal mode. It seems an unrelated issue.
On mx35pdk you can reset the board without powerd off. You should check
the address in kernel for the log buffer (__log_buf in System.map) and
then check it after a reset in u-boot with the "md" command. If we are
lucky, the RAM does not lose its values. Better will be if you have a
JTAG debugger and can you check inside memory directly when the kernel
hangs without rebooting.

Depending on the kernel version, ttymxc0 could be wrong. Have you
checked it ?

No, I didn't change it since it seems not to make any difference. Hope
we're talking about the same, I changed the following and it did not
make any difference whether it was commented or not:
+++ b/board/freescale/mx35pdk/lowlevel_init.S
init_sdram_start:
/*init_sdram*/
- setup_sdram

A first quick try ended up with the following (I'll try harder today:

Because the RAM is already set up via the imximage.

It depends on your mx35pdk. The board can be equipped with one or two
banks. If it works commenting these lines, it means that in your
imximage.cfg you set only one bank. The setup_sdram() sets both banks.

Mmhh...you had already a running u-boot - your problem is moved, because
the kernel is not correctly started.
I think you should start from this condition (the running u-boot) and
try to understand where the kernel hangs. This can be of course
something related to u-boot and in u-boot code, but trying to disable
things that worked can be completelky unrelated.
By the way, if you set CONFIG_SYS_NO_FLASH, you should also set that the
environment is embedded (that means, you have only the default) and
deactivate the flash driver (CONFIG_CFI).

Hi Fabio,
thank you very much for your reply.
> With these values you can create a correct imximage.cfg file for mx35pdk.
Thank you, I'll try my best.
>> $ ./tools/mkimage -n ./board/freescale/mx35pdk/imximage.cfg -T
>> imximage -e 0xA0000000 -d u-boot.bin u-boot.imx
Can you tell me which address I have to append to the -e switch of the mkimage program? I think that my choice (0xA0000000) is incorrect since it is /CS0 memory region of the WEIM. Is it 0x10000000 for internal RAM? And if so, do I have to change the following define within "include/configs/mx35pdk.h", too?
/* Set TEXT at the beginning of the NOR flash */
#define CONFIG_SYS_TEXT_BASE 0xA0000000
> So my suggestion for you is to try to boot from internal boot mode first. Try booting from SD card first as this would be easier.
Could you please give a short explanation, why it is easier to boot from SD than from serial NOR?
