Re: U3S fw 3.12 no heartbeat no cal


1PPS Signal is there at the mcu. Connecting the QLG only to the clock its allright. Connecting the QLG to the Ultimate 3, there is nothing. 1PPS ant DATA are at the MCU.


I decided to flash the mcu.


I have the firmware downloaded and i have a isp programmer.


Which software ca i use to get the firmware on the chip ?
