Other Parts Discussed in Thread: UNIFLASH, HALCOGEN
So, I have a custom board with the TMS570LS1114ZWT on it. It is being operated in conjuction with the TPS65381A, which generates the I/O and core supply voltages, which I have verified. I use an XDS200 debug probe for connecting to the target board using a 10-pin JTAG interface.
I am using CCS v7 (as per customer requirements) to compile and debug my code. At present, I have just a minimal test code, generated using HALCoGen, which does not use any periphery modules. Unfortunately, I can't start a debug session, nor can I upload data to the flash memory (using the UniFlash tool), or perform an Erase Flash cmd.
I have previously tried running the code on the TMS570LS12x dev kit (obviously having selected the correct target chip). This works just fine. To rule out the JTAG interface, I soldered an adapter cable, which turns the 10-pin JTAG connector back into a 20-pin ARM connector, as found on the dev board. This also works without problems, so I don't think the JTAG interface is the culprit.
I have tried testing the connection from within the CCS (from within the target config editor), which works ok.
When I try to launch a debug session, however, I get the following messages in the console window in CCS:
| Texas Instruments XDS2xx USB Debug Probe/IcePick : Target must be connected before loading program. Texas Instruments XDS2xx USB Debug Probe/Dap : Target must be connected before loading program. CortexR4: GEL Output: Memory Map Setup for Flash @ Address 0x0CortexR4: GEL Output: Memory Map Setup for Flash @ Address 0x0 due to System Reset |
Also, a window pops up:
It stays stuck in this state for a while, until finally the CCS gives up with another bunch of messages:
| Texas Instruments XDS2xx USB Debug Probe/IcePick : Target must be connected before loading program. Texas Instruments XDS2xx USB Debug Probe/Dap : Target must be connected before loading program. CortexR4: GEL Output: Memory Map Setup for Flash @ Address 0x0CortexR4: GEL Output: Memory Map Setup for Flash @ Address 0x0 due to System Reset CortexR4: Error: (Error -1141 @ 0x3E418) Device is not responding to the request.

And I get a final popup window:
Edit: Not sure if this helps, but I get different error outputs on the console from time to time:

Edit2: Uniflash seems to work now, if somewhat inconsistently. I can upload the .out file of my project, read memory and perform a chip erase. I only made one real change: I severed the cold reset line, running from Pin 6 of the TPS65381A (NRES) to ball W7 (NPORRST) of the TMS570. However, the operations in the Uniflash seem somewhat unreliable and I can't do step-by-step debugging...
I'll continue to investigate any potential hardware problems. But maybe somebody has encountered this problem before and could give me some pointers?
Any help is appreciated.
Thanks!
