Update OpenLRSng to FW 3.8
Problem: Trying to update the OpenLRSng firmware to version 3.8 failed to due error message "PSP Command Not recognised" after trying to connect the USB to serial adapter to the Tx module
Solution: Flashed the Tx module with the bootloader via the Arduino IDE and USBasp. On doing this I was getting another error message "AVRDUDE: Warning: cannot set SCK period". After trying driver / firmware updates to the USBasp and not being able to solve this error message, i found it didn't really matter after trying a firmware update to 3.8 and it worked anyway!
