Hi,
I am attempting to use U-Boot on a radxa rock2 board, and noticed that the latest release of u-boot doesn't allow the kernel to boot. I am including a boot log below.
I was able to get a working u-boot which boots my kernel by compiling v2016.03. (git://git.denx.de/u-boot.git)
I traced a bit and found two commits which seem to break things, but I stopped there.
1) ed980b8c62fbe17052ec6151a68b5b0be3809485 after this commit I am able to get a working uboot with this patch:
diff --git a/configs/rock2_defconfig b/configs/rock2_defconfig index fd32fb5..c2780c4 100644 --- a/configs/rock2_defconfig +++ b/configs/rock2_defconfig @@ -67,3 +67,4 @@ CONFIG_USE_PRIVATE_LIBGCC=y CONFIG_USE_TINY_PRINTF=y CONFIG_CMD_DHRYSTONE=y CONFIG_ERRNO_STR=y +CONFIG_EFI_LOADER=n
2) c09d29057ab0b04db0857d319c6bff74de31b9c3
I wasn't able to find a solution here.
I am using this toolchain: android-platform-prebuilts-gcc-linux-x86-arm-arm-eabi-4.6 Is there a better option for u-boot in general?
I'm able to test and do some limited troubleshooting, but I don't think I can delve into dram init assembly code. I believe that v2016.03 is sufficient for our purposes, so this isn't critical for us. Just a friendly bug report.
Good luck, Sandy Patterson
