odroidxu3-v2012.07: f7055b383cf349058b0a1e286905c27f9d67cd7f introduced regression: Only one CPU is inicialized

[ynezz]

Hi,

I've compiled my custom u-boot today and noticed slowdown of the whole system as there's only one CPU correctly initialized. This lead me to revert of f7055b3 which fixes the issue and all 8 CPUs are correctly initialized now.

Thanks.

What BL2 did you fuse with the problem. I think you used an older BL2 with your newer u-boot.bin. If you use the HYP enabled BL2 with the re compiled u-boot (without reverting any commit) you should be fine. Use the ones from https://github.com/hardkernel/u-boot/tree/odroidxu3-v2012.07/sd_fuse/hardkernel and please update comment.
