Anton. Thanks for the info you provide.

The code I have actually works fine on MPC8568. It does NOT work on MPC8360.

The value of following register are correct based on the manual. And
the RxBD flag changed as well. I shall see the bit of UCCE changes,
Right? Do I miss provision anything? Is there any other register shall
I check in order to get the interrupt bit in UCCE?

gumr  : addr - 0xfdf02000, val - 0x4000000c
ucce  : addr - 0xfdf02010, val - 0x00000000
uccm  : addr - 0xfdf02014, val - 0x7f010001

Hi All,

Anyone know the difference of QE between MPC8360 and MPC8568?

I am using the QE code working for MPC8568 on a MPC8360MDS board.
However there is no interrupt generated by UCC0. I set the QE working
under loopback mode. The flag of TxBD got changed, but the UCCE
remains the same value. Here is the logs and register value.

I recalling these differences:

QEIC to MPIC vs. IPIC cascading (may be the cause of interrupts
issues).

QE ParIO layout (you may have pins misconfigured):
