Posted on May 17, 2011 at 12:59Hello,
is it possible to use standard bootloader in the system memory via a half duplex interface RS485 transmitter, connected to Uart1 of the STM32 microcontroller STM32F101C8T6?
During sending data from the STM32 bootloader at TxD, the same data will receieved on the RxD pin, in consequence of the loop in the RS485 transmitter. This seems a problem for the bootloader to be since he reacts to it.
The URAT RxD input should be not active during sending or a GPIO output should be active in order to disable the receiver of the RS485 transmitter.
Is it possible with the help of a USB <-> RS485 interface converter to use the standard PC loader from your web site?
