Title: Use a different IQ source for testing UIboard
Post by: pe0f on 17. February 2018, 14:32:49
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 |

Hi Frans,
evey I/Q audio stream should work. Maybe you have to reduce levels (of course symmetrical). But if levels are <3V nothing will be damaged and you can test it out...

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

Hi Frans,
there is no "close" function. The threadstarter can edit his first post and add a [solved] to the front of the topic - that is all which is neccessary.
