How does the UART bootloader responds feedback?

We are designing a project where we would like to use the default bootloader on a LIN connection.


The MCU we plan on using is the STM32F030RC, with external LIN-driver.

The LIN-driver merges Tx & Rx, so everything send will be visible on the Rx.

How does the UART bootloader respond to its own ack/nack or data?

Does it get in a loop where it nack's its own data because it is not a known command?


Thanks in advance!
