In the first sequence at the beginning of the capture right after running OpenOCD target responded with "WData 0x412FC230 reg RDBUFF", which is the pretty correct value for Cortex-M3 r2p0 according to the RM. In second and third sequences target responded with "WData 0x02010030 reg RDBUFF", which might be the problem reported by the OpenOCD, bc "0x003" isn't a valid value for PARTNO. In the last sequence target responded with "WData 0x05FA0030 reg RDBUFF", but I'm not sure if this request really refers to the actual problem. However, I'm actually not really deep in the OpenOCD and trying to understand what is wrong with my setup and why is the target responding with at least 2 different values after reading a RO register value.
