Hi all,
I'm having issues programming a TMS470R1B1M
I have four identical boards each withthe same microcontroller and batch code CA-41C91W. One programmes without a problem the other 3 fail with the same error "CPU-failed to stop".
I have checked the cloack 7.5MHz, 1.8V is good 3.3Volts is good.
Jtag data is going to and from the uP
Osc out is also working
TRSTn is pulled low with 10k
RTclk is pulled low with 10k
RSTn is pulled high with 10k
There is nothing else on the Jtag bus
The IAR software log is as follows

Any suggestions I'm a bit stuck having not used TI processors before?
many thanks in advance..
