Other Parts Discussed in Thread: UNIFLASH
Hi,
I am running into an inconvenience that I hope I can get some help with.
I am using the TMS320F280039 MCU with the XDS200 USB Debugger.
When I start a debugging session in CCS 12.7.0.00007 the system will hang at the OnTargetConnect() Gel Step. If I hit cancel the connection session continues and I can start debugging. I've added prints to the Gel Script and it appears that the following line is never evaluating to true.
while(!(*(int *) (MEMCFG_BASE + MEMCFG_O_DXINITDONE) == 0x3)); /* Wait for InitDone Status */
Can someone explain why the M0/M1 RAM initialization would not occur successfully? It is also worth nothing that I do have the JTAGLock enabled as well and the SecureFlash Configured.
I've attached the entire OnTargetConnect function from the f280039.gel file.
Thanks,
-Colin
