Firmware update over uart I/O pin config

[42bytes]

Hello together

Actual I use the systembootloader to update the device over uart.

Is there a way to reconfigure the unused I/O pin for the system bootloader? Or must this be done via a self-written bootloader?

The problem is that some I/O pins take on a different status as soon as the application for the firmware update jumps into the system bootloader.

Thank you and br

Systembootloader can be used only with pins defined in AN2606
