How to control the SPNIDEN signal in iMX53 qsb?

[zhenyuning]

Hi,

The ARM architecture manual refers different debug authentication signals like DBGEN, SPNIDEN, SPIDEN, and NIDEN. However, from the iMX53 reference manual, I can only find description of how to control the DBGEN signal. Is there anyway we can control the other signals from the board?

Thanks for any help and discussion!

Best,

Zhenyu
