Hello!
Current U-Boot master has broken booting of Linux kernel over UART on A38x.
After transferring image over UART it just prints:
CACHE: Misaligned operation at range [01000000, 014e5d96] ## Total Size = 0x004e5d96 = 5135766 Bytes ## Start Addr = 0x01000000 Kernel image @ 0x1000000 [ 0x000000 - 0x4e0e60 ] FDT and ATAGS support not compiled in
resetting ...
It resets board and does not boot kernel. Note that I'm trying to boot recent 5.15 kernel image, not something old.
I did git bisect and it found following commit which broke booting:
9774462e34faaa64a91eb9c68b438a52d22bba6a is the first bad commit commit 9774462e34faaa64a91eb9c68b438a52d22bba6a Author: Tom Rini trini@konsulko.com Date: Mon Aug 30 09:16:30 2021 -0400
arm: Disable ATAGs supportPrior this commit booting working fine.
Do you have any idea what is with above commit? Or any hints?
Can you provide the full log of what you're doing? And what's in that image you're passing, exactly? Thanks.

OK, and is /tmp/kernel something with an appended dtb then?
Yes, single image suitable for single kermit UART transfer: cat arch/arm/boot/zImage arch/arm/boot/dts/armada-385-turris-omnia.dtb > /tmp/kernel
