Hello dear forum,
In my F103RC project I need to connect USART inputs RX2 and RX1 to each other
( I have my PCB produced already, thats why )
I want use flash loader demo with USART1
my question ;
which usart is used other than USART1 during bootloader function
does RX2 have a function during bootload ? - ( I want it to be floating input without a function during bootload )
is this possible ?
