Use a different IQ source for testing UIboard

Hello,
I want to test my UI board receiver side with IQ signals
Is it possible to take IQ from a different receiver to test the board ?
I want to take the IQ output from my KX3 and feed this to the UI OVI board
What are the pitfalls and can this work ?
Cheers Frans PE0F

Hallo Andreas
I have tried and i did see some data in the waterfall display (used IQ from the PX3/KX3)
Then the display started flashing en turned white
If i connect it i only see a white screen ;-(
I can get in the mode to connect is a a STM in order to reload the boot loader or firmware
It looks like the processors is bricked clock and power i measure are normal as before
Any Tips ?

Hallo Andreas,
I have not mounted them because i want to make sure they where at the right hight if you fit in the housing
In the mean time i have tried with the ilink interface and the cpu is still intact
In the next few days i will try to reload bootloader and firmware via the I link interface

Hi Frans,
yes. 0x8000000 is correct for the bootloader.
Firmware has to be loaded at 0x80010000
