Hi Anish,

Thanks for pointing that out. I ran menuconfig and that fixed the compilation issue however, now I'm getting this error when I try to run it:

spl_load_image_fat_os: error reading image args, err - -1

I guess I'll fool around with menuconfig see if there is something that should be enabled and isn't. (maybe you have a suggestion on this?)

Anyway, I'll post updated defconfigs when I figure it out. Hopefully this is just a config issue.

Thanks, Gilles .

Hi Gilles,

This u-boot version is having lot of changes , they have enabled Kconfig similar to Kernel and having GUI support ( make menuconfig) . so if you are gettting error as you mentioned , try to add Device model configurations and SYS malloc() as :

Steps 1 make <birdland_bav335x config> Step 2 make menuconfig Step 3 Device driver -> Enable driver model, enable Driver model for serial) Step 4 malloc() pool , General setup --> Enable malloc() pool.

Please try this , I think it will work.

Thanks, Anish

Folks,

I posted a patch to add support for bav335x boards (a322aad99de4). The patch was tested against v2015.04-rc1 and worked perfectly but somehow, something was introduced since then which breaks the board support.

There are two main errors I need to fix before posting another patch but need help with the second error.

The first error is easy. Compilation throws: #error "Please define NS16550 registers size." which I can simply fix by defining CONFIG_SYS_NS16550_REG_SIZE in include/configs/bav335x.h ((( Altough I am stil puzzled as to why this was defined as -4 (where?) on v2015.04-rc1 )))

After adding the define, everything compiles up to failing on the final link with:

drivers/serial/built-in.o: In function `get_current': /home/gilles/bbdev/u-boot/drivers/serial/serial.c:389: undefined reference to `default_serial_console' drivers/serial/built-in.o: In function `serial_initialize':

Can anyone please explain what changed between 2015.04-rc1 and 2015.04-rc2 which could cause such a behavior? I have spent the last couple hours re-basing a branch to see where it breaks as to maybe get a clue on what changed but no luck so far. Any tips would be appreciated.

Thanks, Gilles .

Hi Anish,

Yes, actually my board support is based on an older sitara patch and it works when applied to v2015.01. But I was mistaken about the problem. I went back to my original patch applied to v2015.01 and it gives the same error but then moves on to SPL and boots ok.

So I guess it's safe to say that the "fat" error is not the problem. The problem when I compile a74ef40a471d9d4bffb36a8c89744cf6fd631e6f is that it restarts over and over.

Do you have any suggestions how how to find the cause of the constant restart? I actually don't have a debugger for this hardware :-(

Cheers, Gilles .

Hi Giles,

I was browsing the code and it seems it is failing in spl_fat.c file in function spl_load_image_fat_os() and internally calls do_fat_read_at() function. Also I noticed that configuration is very near to am335x( ti sitara) architecture, so probably can try some more configure similar to am335x .

Thanks, Anish
