MPC8306 Ethernet initialization problem

We are developing custom boards based on the MPC8306 and are having ethernet issues on some of the boards.

MPC8306 boot process is suspended during ethernet initialization in the u-boot process.

It seems that the CECR flag bit of QE is set by the core processor, but QE failed to clear this bit, causing the processor failed to continue executing.

Only one of the 6 boards has this problem, the MPC8306 has been replaced with a new one, and the PHY we use is DP83848K.

Sincerely hope to get your help.


Thanks in advance.
