Do you have any update for using latest ATF + uboot? :)
The lastest U-Boot code which incorporates my latest patches is v2015.10-rc4 from upstream U-Boot tree here http://git.denx.de/u-boot.git .
I was running with that patch series OK on top of v2015.10-rc3 (so I've not actually tried -rc4, but -rc4 incorporates my latest series).
I was running that in conjunction with the ATF which switched to UART3 which was commit 9f96699c5b62ff1381d8b8838a66329eff2914ce. That setup was working OK for me.
I tried two ATF versions, one version is to follow up u-boot-readme.txt to checkout commit log:
git checkout 9a97502e8b3247dee95d4f0b48fc5d7154f40609
Finally i saw ATF will trap into exception, so this very likely with memory barrier issues we found before (Or caused by DDR init).
That could be U-Boot relocating itself into the 16Mb TrustZone secured area of RAM. A patch in -rc4 fixes that (05e682d46799de7be0ed3200ae2543d47a35fe7b).
- Also tried latest ATF + uboot but cannot boot up; do you have some extra patches to fix this issue?
Are you using the mainline U-Boot, v2015.10-rc4?
i found the memory node in DTB will be overwritten in uboot, so want to build uboot to debug this issue.
Ok, sounds good :)
regards,
Peter
