4 years ago Conneсt pl2303 usb-to-rs232 to router, setup access, forward remote port to linux host via socat - socat PTY,link=/dev/nc0,echo=0,waitslave TCP:10.9.9.98:333, and try flush - stm32loader -e -w -v -p /dev/nc0 cmp-wiz.bin
and setup jumper boot0 and reset button as need manual..
chines stm32f103c8t6, communicate work in "normal" mode, i can connect to mcu and read/write via minicom -D /dev/nc0

4 years ago I have no experience using socat.
What is the output of the stm32loader command?
Also add the -V option to make it verbose.

2 years ago Looking at the stack trace, this crashes when stm32loader is trying to toggle the BOOT0 pin.
This uses the RTS pin of the UART adapter. It seems your setup does not allow to toggle RTS.
You'll have to control BOOT0 and RESET manually, and remove the functions enable_reset() and enable_boot0() (in file uart.py).

2 years ago You can append "-M" option for skip this functions automatic ?

2 years ago I can add --no-rts-dtr... But first I would like to know if this really works for your use case.
Did you try it already?
hi.
Why flushing not work via network and socat?
