i try to modify linker.lds to make enough memory range , than i got the map files, in the map files the size of .cinit section is very big, maybe this is why the error in last post,

but i have no idea why this section size is big like this.

please give some advice for solving this errors.

any helps would be grateful!

Regards!

Hi Yan,

This seems to be a different issue. Can you try do below commands:

cd $PSDKRA/vision_apps
make sdk
cd $PSDKRA/pdk/packages/ti/build
make keywriter_img_clean
make keywriter_img

Best Regards,
Keerthy

Hi Keerthy,

I tried those commands, but it makes no difference from the previous results.

I also found there are a difference between normal bootloader(tiboot3.bin) and keywriter for loading the sys_fw(tifs.bin or tifs-hs-enc.bin),

1) normal bootloader

From POR, the loading sequence is like below:

RBL will load sbl(tiboot3.bin) from storage(ie. sd card), and then sbl will load sysfw from sd card(like the following function call sequence)

void SBL_SciClientInit(void)

-> SBL_ReadSysfwImage(&sysfw_ptr, SBL_SYSFW_MAX_SIZE);

-> Sciclient_loadFirmware((const uint32_t *) sysfw_ptr);

2) keywriter

I read keywriter boot process from keywriter source code, the sequence is like below:

At first, RBL load keywriter image from sd card, and then the difference emerges, keywriter will load sysfw through an array(variables)

I guess this array was been declared for storage sysfw binary(maybe it's size is about 0x447dd),

so if the version of linker.lds script is not matched with the keywriter installer(PDK_OTP_KEYWRITER_ADD_ON_07_01_00-linux-installer.run)

please help to confirm if this mismatch issues exists.

Best regards,

Yan

Hi Yan,

I believe this was due to VPP not enabled correctly. I learned that the issue is fixed & hence closing the issue.
