1  Hardware and U-Boot firmware / U-Boot stuff / Re: SheevaPlug: no boot from SDHC after u-boot upgrade to DENX 2012.04.01-2 on: September 08, 2012, 11:00:46 AM
ruidc I have 3.5.2 working on my sheevaplug booted with 2011.12-3

Looked at the patches that were in 2011.12-3 and it seems the kirkwood-disable-l2c.diff is there as well so I'm guessing that 2011.12-3  which works well for me with SDHC/MMC will boot the latest kernels. I'll give that a whirl.

Thanks TBM my efforts got me a u-boot that can get the kernel CRC checked, but I found that it was failing to saveenv properly. ruidc I don't think the kernel version is any kind of problem as it works fine with older u-boots. The reason this is of interest is the l2 cache bug that prevents older u-boot from booting kernels > 3.2.

Well I have had at least some success. I applied just one of the patches from 2012.04.01-2 (kerma-sheevaplug-mvsdio.diff) which adds in the SD related stuff to the very latest denx uboot code. Using the openocd and the u-boot.elf from that build I do get the SD boot to work.

If you want to try more bravery you can inhibit the crc check that causes the failure by using the environment variable verify (use setenv verify no). Of course that assumes the problem is only in the crc check. If that's not the case and the kernel has been offset loaded or something then all bets are off and you could trash the plug.

I have also tried the http://people.debian.org/~tbm/u-boot/2012.04.01-2/sheevaplug/u-boot.kwb uboot and had exactly the same result. I guess there is some error in the patches as applied there. You can revert to pingtoo 3.4.27 and that should get you back to where you were before. I have looked at the patches from here http://people.debian.org/~tbm/u-boot/2012.04.01-2/u-boot_2012.04.01-2.debian.tar.gz and will attempt to patch the latest denx code and rebuild. Did you try and contact tbm?
