Steve,

 

Would you be able to confirm that this soft-reboot failure still occurs
when using the UBL supplied in the SPRAAI4 app note?  Or if not just
provide some details on your EVM setup where you did have the problem?
You were booting from NAND, your kernel was in NAND, your filesystem
image was in NAND?  Any other details?

 

Thanks,

Daniel

Hi, 

Our embedded engineer has solved reboot problem by modifying UBL code.
I am sorry that i am not allowed to share this part.

Hi Steve,

I reproduced your soft reset problem on our boards and on evm. 

In the mean time TI provided us UBL source code, so I did some patching.
I implemented workarounds for both soft reset and STM NAND flash. Code
works OK at least for me. I submitted patches to Roger.

Hi Roger,

This situation is happened on standard evm and it works fine when using
NOR boot.
We use the kernel from dvevm 1.10 but elder u-boot.

Currently, we manufacture our own board and use STM flash.
So we face the same problem as Ivan faced. The flashwriter from TI can
not work on our flash.
Our hardware engineer is working on this issue now.

Steve - some more questions to help us track this down :-

 

Is this on standard evm or custom hardware?

Which version of Uboot are you using? - Is it the latest from the ti
extranet?

Which version of linux kernel? - the one that comes with dvevm v1.10?

Does reboot work successfully from NOR or is it also failing from NOR?

Does reboot work successfully when using the MV filesystem, rather than
your ramdisk?

Hi, 

Does anybody face the following problem? Any comment?

Thanks a lot.

Steve


  I storage kernel and ramdisk on nandflash and boot evm form it, but I
can't reboot my system by submit "shutdown -f -r now" or "halt -f" both
and system will show "system is reboot now" or "Booting PSP Boot Loader"
and then no any response. As I know, "Booting PSP Boot Loader" was
printed by boot loader, but I don't know why it's not go on. Any
commands?

P.S "halt" and "shutdown" were copy form evm hard disk (under /sbin) not
soft link to busybox, any I copy all /etc form evm hard disk to my
ramdisk.
