I have manually verified the FLASH bytes are correct after programming, but the -v option results in "Error: Data mismatch found at address 0x10000000 (byte = 0x21 instead of 0x00)" and the process stops.
Isn't 0x10000000 a CCM address and why is it being tested and failing? See terminal output below:
"C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\STM32_Programmer_CLI.exe" -c port=USB1 -d "fw.hex" -v -g 0x08000000
