Hi yj L,

have you found a solution for the problem?

I'm also having trouble to get the 5775K into debug mode and read/write with Nexus after entering debug mode.

Regards

Are you creating you own JTAG debug tool?

Did you follow AN4365?

yes

When reset is assert ,micro  need waite for a long time and shift-ir "211"(bypass) before Set the OCR[DR] and OCR[WKUP] bits.

after entering debug mode,read-write sram will go wrong
