Hi,
I'm facing an CPU hang issue while testing U-boot/ATF 5.4.47 on iMX8M Nano EVK.
(It happens every time I reset)
I confirmed it boots up all the way to Linux prompt with U-boot/ATF 4.19.35).
I just switched "flash.bin" with everything other unchanged.
Please give some clues if any.
Log(CPU hang?)

How did you solve this problem?
Are there any technical details regarding kernel or uboot jumps
Hi kyungjun
uboot and linux versions should be aligned, as described in linux release note document on link
So for U-boot 5.4.47_2.2.0 recommended to use L5.4.47_2.2.0
https://source.codeaurora.org/external/imx/linux-imx/tree/?h=imx_5.4.47_2.2.0
Best regards
igor
Hi Igor!
Can you please explain the technical details for why u-boot is particular about what kernel version it boots?
Kind regards
Simon
I would appreciate any help from you and Igor
Thanks
did you fix the problem after change to L5.4.47_2.2.0?
