I'm having trouble getting my Bela and CTAG Beast setup to upload anything from the IDE. Initially, attempted uploads returned:
audio frame 1267552, errorCode: 3
McASP unexpected transmit frame sync occurred)

I found this discussion on the forum
https://forum.bela.io/d/4657-mcasp-unexpected-transmit-frame-sync-occurred

I double checked my stack and everything is setup correctly according to this page:
https://learn.bela.io/using-bela/technical-explainers/configuring-ctag/

Now, when I try to run the code from the IDE, the upload process never ends and no error codes are returned. Instead, a solid red light appears on the Bela Cape (D6).
Very new to Bela. Any links or suggestions would be helpful, thanks.

Can you try swapping the two capes and reconfiguring the two sets of jumpers?

  • kmg replied to this.

    giuliomoro I could, but I have no experience soldering and I don't have my own tools for that. Are there other options besides swapping capes, or is that the first thing to do?

      There's no soldering involved. You can remove each cape as shown here:

      I separated the capes and ensured that the configuration had one leader and one follower. I double checked that the Bela Cape is working when attached to the BeagleBone Black (no FACE Capes attached) and it definitely is. When I have the Bela Cape on top of the stacked FACE Capes (bottom-top: BeagleBone Black, FACE (follower), FACE (master), Bela Cape), the code does not upload and the Bela Cape displays a solid red light.

      I just tried stacking the bela cape on top of the face capes and noticed the bela had the blinking blue light. ran the code and it worked for about two seconds. I readjusted the bela cape to see if it was just not connected securely, and the red light came back on and audio stopped. it's been displaying the solid red light since. any thoughts?

      When you get a red light, what do you get printed on the IDE console?

      Try updating your board to the latest dev branch (see here) and see if that works for you.


      I updated the board with this dev branch through the IDE. The red light still comes on and this is the new error.

      can you run this in the console at the bottom of the IDE?

      grep REG_ADC_CONTROL_2 core/Spi_Codec.cpp

      and show the result here
      ?

      since reconnecting bela after updating the board to the latest dev branch, i have not been able to access the IDE.
      i reflashed my sd card and updated my board with the latest master branch through terminal.
      after this point, still no IDE access despite macbook recognizing Bela board.

      That's weird. Can you run this from a terminal on your computer ? curl bela.local : what do you get? Also show the output of ifconfig.

      curl bela.local output:

      curl shows that the board can be reached, the IDE works and is up and running. ifconfig shows that you can use either bela.local or 192.168.7.2 .

      Good. Try accessing the board making explicit the http protocol: http://192.168.7.2 or http://bela.local

      okay. tried both explicit addresses again and still yields site as unreachable

      Is it possible that you have some extensions in your browser that prevent you from accessing http pages? Can you try a different browser, e.g.: Safari?

      yes, browser was preventing access. odd because i had access through chrome before and didn't change settings, but IDE comes up in safari.
      i ran "grep REG_ADC_CONTROL_2 core/Spi_Codec.cpp" in IDE console and received the same output as before (after latest dev upload)

      updating Bela with master zip file through IDE to test again
