since appr. 2 Months we have the problem, that we cannot program our product anymore. Nothing changed on the setup. We even replaced the programmer but still having the same issue.
For programming the device we use a Signum JTAGJET-C2000F-ISO programmer and the software used to program is the "TMS320C28xx On-Chip Flash Programmer". We tried to replace the programmer with a different one, which worked, be due to the controller is in a medical device we try to avoid to change the programming sequence.
