My board using i.mx6ull hangs after kernel startup.

Latest reply on Sep 21, 2019 by Fumitaka Takahashi

Hi, everyone in the NXP community

 

I am building a new BSP with a new board using i.mx6ull.
I calibrated DDR, bitbake u-boot and Linux kernel and root FS, and wrote the image to the board with Mfgtoo.

 

However, there is a problem that the system hangs immediately after the kernel boot is finished.

 

This problem always occurs every time.
