Hi John,

?

Hallelujah, praise the Lord worked! The only thing I found different was you said that you checked the universal serial bus controllers for the boot loader. It was in the universal serial bus devices not controllers.. That may be computer specific.

Anyway thank you very very much. If I get the chance I'll document that with pictures, a little bit more than what you did. If it's worth sharing I'll share it.

?

Kind Regards,

Dave

Purchased from Mirfield Electronics so it should be good. Downloaded the TinySA app which works well and connects to the device successfully. So far so good.

When I put the TinySA into DFU mode to initiate a firmware update it promptly loses connection with the PC so firmware upload is not therefore possible.

So I guess I am doing something wrong but cant figure out what. I have watched Youtube videos but they have not replicated the problem I am having.
