Question
CLI fails to mass-erase the flash memory
Hi
The command to download our firmware is as follow (with the option bytes display to show that protection is disabled):
STM32_Programmer_CLI.exe -c port=SWD mode=HOTPLUG -ob displ -e all -d C:\Temp\cu.hex -d C:\Temp\data.hex -v -rstThe result always gives an error for the flash mass-erase:

MCU Reset
Software reset is performedWhen I replace the mass-erase with the request to only erase the sectors of interest (-e [0 15], I got no error but also no guarantee of the operation done:
Existing specified sectors are erased successfully
Protected sectors are not erasedAdditional info: if the erase step is not provided, the failure happens while attempting erasing sectors before the first download.
Why this error ?
Many thanks in advance.
