Other Parts Discussed in Thread: UNIFLASH
When programming the LRPC demo into an ISK board the new board programs as expected first time around. The latest UniFlash 5.0.0.2289 is used. Boost Board with ISK mounted is powered up with SOP2 closed and the reset button cycled for 2-3 seconds. The binary is chosen (LRPC_lab_xwr68xx.bin), the com port selected (XDS110 used as USB to serial) and the device programs.
If that process is repeated on the same board with the same procedure the process hangs UniFlash with 2mm of the progress bar green instead of the usual 20mm and advancing with the programming progress. This seems to indicate that once programmed the ISK can not be re-programmed.
Other threads have reported similar issues but their fix was to close and reopen fixing the issue. That does not work In my case.
What DID work was to remove the SOP2 jumper and allow the LRPC demo code to boot. Verification of the running of the code can be monitored by looking at the UART channel on the radar at 115.2Kb. You should see the following output after SOP2=0 and a NRST. NOW if you go back and repeat the process above with SOP2 closed the part will again program.
Can you explain why it works like this? Very important for those that want to design field upgrade utilities into this part.
