Hello Georges,
I got my TinyPico board yesterday and followed your video guide. When I start compiling it does some progress, but end in this message:
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
exit status 1
Compilation error: exit status 1
I never worked with such tools before, do you have a clue, what goes wrong?
Thanks a lot,
Uli
Sorry, forgot some infos:
MacOS 14.2.1
Apple M1 MacbookPro
I guess I found the solution, just installed the developer tools and it worked so far. I hope I can finish it now. I will report.
Thanks,
Uli
Sorry to bother you again.
It started uploading now, but the TinyPico get's not in it's idle mode, the multicolor LED stays dark. Just the blue one en the small amber one is flashing. The serial window just shows a lot of Question marks. If I hit the small switch, there is some communication, though. Since I do not get an error message, I guess it is best to post the upload here, if I can provide any other information, please let me know. I am stuck now.
Thanks,
Uli

Hard resetting via RTS pin...
Set the serial console to 115200 bps, reset the board, what do you see?
Currently this, but I do not get the board to reset that the multicolor led lights up as at the start. I did not found the reset procedure in the EM help files anywhere.

Hi again,
I did what I was able to, but no luck. I am stuck currently, with no idea what to do, to get it running. Any help is very appreciated.

The question marks in the console output means you're not at the correct bit rate for the board. Try to setup the serial console to 115200 bps and hit the reset button on the TinyPICO.
This is what I get with the correct serial bps (I hope) The earlier is before trying to upload the firmware, the otherone after uploading it. After setting the right speed I hit the reset button as you said.
Thanks for your help!
From the look of it, you are flashing an empty sketch. You need to open the source code you want to flash in the IDE. Navigate to where you downloaded the source code, and double click on the .ino file. It will open the project in the IDE and then you can flash it.
Hi Georges,
you nailed it, thanks a lot! I do not know why I missed this step at first but anyway, it works flawless now. Radiomail and the aprs.fi iOS app do find the B.B. Link and communicate as intended with my TH-D75. Great project!

Uli
