Tool/software:
Hello,
I have a custom board with a USB to UART connected to the ROM bootloader UART pins. There is no button for the bootloader backdoor.
I can flash the device the first time using Flash Programmer because the uC will boot into the bootloader when there is no valid image.
I want to use the ROM bootloader for firmware updates. To do so, my application will receive a custom UART command to enter flash mode.
How can I reboot into the ROM bootloader from my app (it uses TIRTOS) without using a bootloader backdoor pin?
Thanks.
