Hi,
I have a problem while debugging M3 core of F28M35H52 device.
I have a custom board and I use XDS100v2 to connect the device. My program is very simple: it is a modified Blinky example with minor modifications, primarily - more pins are assigned to C28x core.
So, I could load th program several times and the debugging worked allright. At some piont the load failed with the following message:
Cortex_M3_0: Flash operation timed out waiting for the algorithm to complete. Operation cancelled.
Cortex_M3_0: Error during Flash verification (Flash algorithm returned error condition). Operation cancelled.
Cortex_M3_0: Flash verification returned error condition. Operation cancelled.
Cortex_M3_0: Please make sure the memory location you are programming have not already been programmed.
Cortex_M3_0: Error during Flash verification (Flash algorithm returned error condition). Operation cancelled.
Cortex_M3_0: Flash verification returned error condition. Operation cancelled.
Cortex_M3_0: Please make sure the memory location you are programming have not already been programmed.
Also, when I connected to the core (after the problem appeared, but before I closed the debugging session), I could check the contents of core and ADC_result registers, but not of GPIO, CAN etc.
I tried to use Uniflash and it helped: I can erase the device and load a program to it (LED blinks), but I cannot access it from CCS. I use CodeComposer v. 5.5.0.00077 and I did not update or modify any CCS components between the successful and unsuccessful device loads.
