Part Number: PGA900
Tool/software: Code Composer Studio
I recently upgraded my toolchain from CCSv6 to CCSv7. I created a new PGA900 project and used the default configuration. After a bit of work mucking about with includes I was able to get my old application code to compiler in the new project with the new toolchain, but I can't get the debugger to connect. The error message I get is:
CS_DAP_0: Error connecting to the target: (Error -1170 @ 0x0) Unable to access the DAP. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 6.0.576.0)
I tried lowering the JTAG speed from the default of 10 MHz to 1 MHz and it had no effect.
If I open PGA900.ccxml and try the "test connection" item, I get the following error message at the end of the output log:
-----[An error has occurred and this utility has aborted]--------------------
This error is generated by TI's USCIF driver or utilities.
The value is '-230' (0xffffff1a).
The title is 'SC_ERR_PATH_MEASURE'.
The explanation is:
The measured lengths of the JTAG IR and DR scan-paths are invalid.
This indicates that an error exists in the link-delay or scan-path.
