I am using Eval boards for the TMS320F28388D and CCS v10.4. All four that I have get this -2131 error. I have gone through the process described here: https://e2e.ti.com/support/c2000-microcontrollers-forum/310311/error-connecting-target-2131-0x00-unable-to-access-device-register to no avail. Is there another way to get this target to talk to CCS again?
