We use several operations with the CLI tool to configure and program our device. The final operation sets the RDP for code protection.
Following this, we see:
Warning: The core is locked up
This is confirmed by the code not executing (non responsive).
On the dev board, hitting a reset button doesn't seem to clear the problem.
In the product itself, the unit is sealed with battery permanently connected, so power cycle isn't possible.
Have tried adding -s option without success.
Everything works prior to the final step of setting RDP:
STM32_Programmer_CLI -c port=SWD reset=Hwrst freq=8000 -s -ob RDP=187
(187 is 0xBB)
Suggestions?
