[U-Boot] u-boot.img size limit for spl fat load ?

[U-Boot] u-boot.img size limit for spl fat load ?

[Ayoub Zaki]

Hello list,

I'm using u-boot-2014.10 and trying to build it with LCD support for the
Beaglebone black to include a Boot logo image.
It seems that spl hangs while fat loading  a 2.8MB sized u-boot.img  !
I reduced the the logo header file and rebuild u-boot, that worked for a
1.6MB sized u-boot.img.
Is there any size limit for u-boot ? how to increase the memory allocated
by spl ?

Thanks you.

There should not be a size limit for SPL fat load.

What may happen is that SPL code is overwritten before it exits, or
U-Boot itself is corrupted after being loaded.

I assume you've seen the SPL banner and not the U-Boot one; that alone
does not tell us whether SPL or U-Boot did hang. Can you build U-boot
with debug enabled? If this results in too big an SPL image, then try
and at least enable debug for the image chainloading parts, so that you
can see how far SPL code gets run.

No problem.

[U-Boot] Fwd: u-boot.img size limit for spl fat load ?

  Hello Albert,

  First tank you so much for inversting your time for replying.

  I put some printf in the code and SPL is hanging in spl_load_image_fat
function.

  I also enable the DEBUG messages here the complete log file :

  http://pastebin.com/raw.php?i=BwUJXDDb
  So I suspect that SPL is not allocating enough memory to load u-boot.img
  but I can't find where this size limit is set and where I can change it.

  Cheers,

  Ayoub

This could be an explanation, but so could be loading the U-Boot image
over SPL BSS if it resides in DDR, or SPL malloc'ed data; and I guess
that if the U-Boot image file size was smaller than a hard-coded limit,
there would be a warning or even an error.

Can you check CONFIG_SPL_BSS_* and CONFIG_SYS_SPL_MALLOC_* definitions
against CONFIG_SYS_TEXT_BASE and file size?

Same goes for SPL stack if it is placed in DDR.

[U-Boot] Fwd: u-boot.img size limit for spl fat load ?

[Ayoub Zaki]

I checked the SPL Memory allocations :

CONFIG_SYS_SPL_MALLOC_START="(CONFIG_SPL_BSS_START_ADDR +
CONFIG_SPL_BSS_MAX_SIZE)"
CONFIG_SPL_TEXT_BASE=0x402F0400
CONFIG_SPL_BSS_MAX_SIZE=0x80000
CONFIG_SPL_BSS_START_ADDR=0x80a00000

My U-boot.img is arround 2.8MB

I increased the CONFIG_SPL_BSS_MAX_SIZE to 0x400000 but it did not improve
the result, for me is not clear how to play/adjust those values ?

CONFIG_SYS_TEXT_BASE=0x80800000
and
CONFIG_SPL_BSS_START_ADDR=0x80a00000
So the maximal size of u-boot to avoid a memory address colision is
0x200000 = 2MB !

I set TEXT_BASE to :

#define CONFIG_SYS_TEXT_BASE            0x80600000

Now u-boot.img can be up to 4MB sized and it solved my problem :)

Thank you very much for your help.
