I just recently purchased a pocket beagle 2 industrial version and wanted to develop some code for execution on the R5F real time MCU running in parallel to the DM functionality. I have found plenty of example code for such projects in TI CCS so I have a good starting point. I went through the startup for my board and got it all set up with a debian minimal image so all was good until I tried to do basic connection from CCS via Tag Connect and my XDS100v3 olimex debugger. No matter what I do I cannot seem to get even the most basic connectivity check from the debugger tools to say anything other that the -233 error, all bits stuck high. Just to point out what I have checked and tried:
- I have the the TC2050-ARM2010 adapter and soldered the nTRST jumper
- I have the TC2050-INC-NL and have the tag clip connectors for retention.
- Again using olimex xds100v3 and made sure to set the jumper to use the ARM connector
- I have tried many different boot methods with primary being hold down user button while powering up board to prevent uboot running.
As a side note I have used this debugger for C2000 projects so I know it works for those (as in hopefully not broken). I have done a lot of searching and checking for possible known issues or ways I am setting things up wrong but at this point I have hit a total road block. I am not a novice at this by any means, I have done quite a few projects for real time MCU operation, however this is my first foray into the TI ARM SoC space so I am hoping I am just missing something basic.
