Hi Peng,
Where do you get the kernel source code and which version? NXP release or Linux kernel upstream? Also ATF/U-Boot version?
- Kernel: Mainline (5.4.66-rt37) + PREEMPT_RT + your power domain patches - U-Boot: NXP (2020.07) - ATF: NXP (v2.0) https://source.codeaurora.org/external/imx/imx-atf/
Do you have a debugger to see where it hangs?
Unfortunately not.
If you point me your version, and source, I could give a try in my side.
Thanks, let me know if you need anything else. Regards, Aaron
