Posted on March 18, 2012 at 22:01I am downloading my application to the F103 with flash loader demo software via uart1 can I also use uart 2 or 3 or 4 for downloading ?
Well, not on the STM32F103, the STM32F2 and STM32F4 offer other alternatives, as do some of the connectivity series as I recall. For the F1's the USART1 should be committed to programming/debug/telemetry output to provide you the most flexibility.
If you build your own loader you can use any port you want.
