Here it is: Please add this line of code as a part of board initialization before L1/L2 memory initialization and after GEM reset completion, file name is platform.asm.

Ivan – many thanks indeed for your hard work on this and your patches. We are reviewing and will get back to you. ~Roger _____ From: Steve Yeh [mailto:[EMAIL PROTECTED] Sent: 06 March 2007 02:33 To: Ivan Tonchev Cc: Monk, Roger; [email protected] Subject: Re: reboot fail when using nandflash Hi, Our embedded engineer has solved reboot problem by modifying UBL code. I am sorry that i am not allowed to share this part. Steve 2007/3/5, Ivan Tonchev < [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> >: 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. Ivan Steve Yeh wrote: 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 2007/3/2, Monk, Roger < [EMAIL PROTECTED]>: 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? ~roger _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Steve Yeh Sent: 02 March 2007 10:41 To: [email protected] <mailto:[email protected]> Subject: reboot fail when using nandflash 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. _____ _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
