I've swapped the VTX in my original Crusader from an SP1 to an SP3. The original crusader runs on a naze32 and I'm using a spektrum serial receiver so uart2 is permanently occupied. I could use uart1 and unplug when I want to plug the USB into the naze but I would prefer to use one of the softserial ports at 19200 baud.
I think I will need to re-flash the SP3 OSD to change the baud rate but I've not found any discussions about this online. So, three questions:
Has anyone tried to flash the SP3 OSD?
Can it be done over the USB interface or would I need to run an FTDI adapter into serial leads?
Will the OSD run OK over a 19200 serial link?
