Re: TX53: Not Bootable from next tree

[Peter Wippich]

Hi,

got the same problem here. Double checked Board Version (8030) and
that I have the right binary (compressed with flash header). After 
flashing and reset nothing happens....

Used default config tx53stk5_defconfig.

Swiched back to old u-boot for now.

Regards,

Peter

I'll recheck when I'm back in the office next week. I have no idea what
is going wrong atm.

I'm back in the office now and realized that we have the 1011
revision in our remotelab. That at least explains why I can't reproduce
this issue. Unfortunately I can't find the 8030 revision anywhere in the
office, I'll wait for my collegue.
In the meantime, could you try removing the call to
imx53_init_lowlevel() and try booting 2nd stage (from U-Boot or
redboot)?

Hi Sascha,

bad enough my test board is out for some customer tests. I'll try a second 
stage boot as soon as it is back.

Best regards,

Peter

Hi,

> redboot)?

2nd stage booting TX83-8030 from redboot works with and without call to
imx53_init_lowlevel (boards/karo-tx53/lowlevel.c)

I've also looked at the DCD sequence at the beginning of the redboot and
bb (CONFIG_PBL=y) binaries and saw, that what set's them appart is:

flash_header.entry RB: 0x8FFC0000
flash_header.entry BB: 0x71000000

flash_header.boot_data_size = 0x1fd87;
flash_header.boot_data_size = 0x40000;


Barebox has an additional DCD Item compared to redboot:

arch/arm/boards/karo-tx53/dcd-data-xx30.h line 15:
DCD_NAME_XX30[] = {
	DCD_WR_CMD(0x21c),
	DCD_ITEM(0x53fd4068, 0xffcc0fff),
	DCD_ITEM(0x53fd406c, 0x000fffc3),


The DCD_WR_CMD(0x21c) duplicates the the last entries of the
flash_header_section structure:

arch/arm/boards/karo-tx53/flash_header.h line 68:
	.dcd.command.tag	= DCD_COMMAND_WRITE_TAG,
#ifdef CONFIG_TX53_REV_1011
	.dcd.command.length	= cpu_to_be16(sizeof(struct imx_dcd_command) +
sizeof(dcd_entry)),
#elif defined(CONFIG_TX53_REV_XX30)
	.dcd.command.length	= cpu_to_be16(0x21c),

So the DCD_WR_CMD(0x21c) seems to be superfluous.



I've adjusted entry address, the boot_data_size, and removed the
DCD_WR_CMD entry, to match the flash header to that of redboot, and
flashed that. That didn't show any improvement.

Also here the situation is the same with and without imx53_init_lowlevel.


Cheers,
Christian

[TX53: boot fixes 0/2] Make TX53 bootable again

[Christian Kapeller]

Currently KaRo TX53-8030 soc module support is present in next branch, but
compiling the default config tx53stk5_defconfig results in an unbootable image.

This series 
 * makes the TX53-8030 board boot again [1/2]
 * fixes compilation of the TX53 board with PBL_IMAGE=n and DO_LOWLEVEL_RESET=n [2/2]

  tx53: Fix unbootable TX53-8030.
  tx53: remove reset() when not doing lowlevel init.

[TX53: boot fixes 1/2] tx53: Fix unbootable TX53-8030.

[Christian Kapeller]

This patch remove a superfluous DCD command in TX53-xx30 flash header.
The entry DCD_WR_CMD(0x21c) just duplicates the contents of the last
imx_flash_header_v2 struct member dcd.

Removal of this DCD entry is needed to make the TX53 board boot again
from NAND.

[TX53: boot fixes 2/2] tx53: remove reset() when not doing lowlevel init.

[Christian Kapeller]

This patch fixes a linker error when PBL_IMAGE=n and DO_LOW_LEVEL_INIT=n.
In this configuration the symbol reset() was present multiple times,
and prevented the barebox image to be linked.

You're welcome. After all, I am happy to enable others to use hot piece of
boot software on the Karo hardware. Also it is good to see, that other
people are using it.

Cheers,
Christian

Until now I've used bb in a 2nd stage configuration on top of the supplied
Redboot, and it worked without any problem.

Additionally I had CONFIG_MACH_DO_LOW_LEVEL_INIT disabled which skips
another pll setup step, that was already done by Redboot.

Yes, I did check for the correct board revision, and am using the
correct one: CONFIG_TX53_REV_XX30=y

I've noticed, that the link target changes depending on build
configuration. So I've flashed the file pointed to by barebox-flash-image.

Just tried that, but without changed result.

Currently I am trying to get my PEEDI JTAG probe working with the
board, but until then I stay in the dark.

Christian

I just tested that it works for me as second stage. I can't test 1st
stage atm as I currently have no physical access to the board.

Some guesses: Have you checked the correct the correct board revision in
the config? It's the default, so I assume it's correct.

Are you using the barebox-flash-image link or barebox.bin? You have to
use the former because it's a compressed image.

You might want to disable compressed image support in
 General settings ->
  memory layout ->
   [ ] pre-bootoloader image

And see if that works.

Sascha

TX53: Not Bootable from next tree

[Christian Kapeller]

Hi,

I've just flashed barebox from the next tree onto a TX53-8030 module,
and have to report, that the board won't boot.

Currently I've tried to run it with MMU off and setting the text-base
to 0x71000000, with no positive results.

I'll do further investigation, but meanwhile does anyone have barebox
running on a TX53 board?

Cheers,
Christian
