From my testing no--it wouldn't be a good idea.

My plan is to do it from the STM32F factory bootloader.

I know the write protection can be done.

Can the STM32 factory bootloader be customized?

The STM32F1xxx factory boot-loader can not be customized by users, However STMicroelectronics is maintaining it and may modify /enhance by adding new features.

Yes, you can set the read protection from your custom bootloader, However you can not remove it since it will erase also your custom bootloader. In general usage, the Read protection feature should be set in the final stage just before shipping your end-product and should be always active during the product life.

I enabled the read protection in my boot loader, then I could not program the MCU via SWD using the Jlink, is this normal?

do I have to disable the read protection, so I can continue developing my firmware?

for my case, i can only use the factory bootloader to disable the RDP, is there any other way cause my UART1 is using by other device?

I'm using STM32F103VCT.

thanks,
