Re: [U-Boot] Same U-Boot for smdk6400 and smdk6410...?

Dear Minkyu Kang & Naveen Krishna Ch, Thank you both for your quick responses. Having looked at include/configs/smdk6400.h, it seems that there is indeed a little work to be done before the SMDK6410 is fully supported. :-( May I please ask if either of you have access to the source for the version of U-Boot (based on 1.1.6) currently used for the SMDK6410? Starting from working code is usually a good idea. :-) Thanks again, ....Nick Pelling....

[U-Boot] [RESEND:PATCH-V4] OMAP3EVM: Added NAND support
by hvaibhav＠ti.com 06 May '10

06 May '10

From: Vaibhav Hiremath <hvaibhav(a)ti.com> The EVMS have been shipping with NAND (instead of OneNAND) as default. So, this patch sets NAND as default. To choose OneNAND, define CMD_ONENAND instead of CMD_NAND in the config file omap3_evm.h, Changes from V3 :- - Added undef statement for CMD_ONENAND.

[U-Boot] Same U-Boot for smdk6400 and smdk6410...?
by Nick Pelling 06 May '10

06 May '10

Hi everyone, Can anyone please tell me if the smdk6400_config / smdk_noUSB_config is suitable for using on the smdk6410 (i.e. for the S3C6410, Samsung's heavily updated version of the S3C6400)? While I can see patches related to the S3C6410 going in, I can only see the S3C6400 target in the u-boot-samsung git, wondered if I was missing something obvious. :-) Thanks, ....Nick Pelling.... // Surbiton, Surrey, UK

[U-Boot] change root password
by Nuno Cardoso 06 May '10

06 May '10

hi, How can I change root password?? I try this: 1) stop u-boot and add "init=/bin/sh" to the bootargs variable; 2) boot 3) passwd -d root (inside shell) but this doesn't work!!!! When I reboot the machine, I cannot login with a new password. Thanks, Nuno Cardoso.
