Title: Audio codec WM8731 not detected
Post by: Co on 16. February 2019, 11:48:22
Good afternoon,
When I power-on my MCHF-OVI40 i sometimes get the error message as per above. I suspect a bad solder joint. It would be helpful to know when the error message is being generated in order to limit the problem search. I suspect at start up of I2C. Is this correct?

Hi Co,
yes. The problem must be located in I2C lines to codecs or (!!) power supply of codecs.
Good luck!

Hi all,
I got also this error at startup of my mchf/ovi40 transceiver, are you success to resolve it ?
Andreas, I found this old post https://github.com/df8oe/UHSDR/issues/961. In this post you wrote that the IC2 speed can be changed, I would like to test this, but I could't found the menu in the Configuration menu. I use the last version of the firmware, is it still possible to do this with this version ?
Regards.

Hi all,
for information, solved for me by the replacement of the 3v regulator KA78RM33RTF, there was no 3v but less than 1v.
