Does a RX have to be connected for it to stat logging?
The board came with firmware loaded that allowed me to do static calibration.
After re loading firmware it now does nothing.
Only a solid red light after power up.
I did remove J4 after flashing.
I will get the PWM>PPM converter going while I wait.
Back in business.
The uSD card that worked before now does not after the firmware update.
It boots with no card installed.
The card works fine the PC
Fortunately I had a few cards around so got another that the AQ was happy with.
