Apologies if this has been addressed, but my searches didn’t turn up anything.
There are a couple of threads out there that brush on the subject of not seeing the ROCC bit of the EJTAG CONTROL register clearing:
but no resolution. I’m currently using a BusBlaster v3 with OpenOCD and am probing the JTAG signals with a Saelae Logic 16 as a sanity check. No matter what I scan into the DR after selecting the ECR, I always subsequently scan out 0xC0000000.
I’d really like to make use of this combo of OpenOCD and BusBlaster for low level JTAG access. Can anyone point me in a direction to move? I’m happy to read docs, look at examples, hack some code.
