Week 7 – Update MMDVM HS Duplex Firmware

To start this week, I updated the firmware on the duplex MMDVM hot spot board. Follow the steps below to do that.

From where I left off previously, I still needed to select the board/modem in the configuration first.

Selecting the Board

  1. Login to the Pi-Star dashboard and click on the configuration page.
  2. Under “General Configuration” find the option that says “Radio/Modem Type.” and select the MMDVM board that you’re using. In my case I selected the MMDVM_HS_DUAL_HAT for Pi (GPIO).
  3. After making your selection, don’t forget to click “Apply.”

Update MMDVM HS Duplex firmware

Next we’ll update the firmware.

  1. First open the “expert” tab and then click “SSH Access.”
  2. Login with the pi-star user.
  3. Run the following command:
    sudo pistar-update
  4. When the update is complete you should see the following:
  5. Next, restart the Raspberry Pi by going to the “Admin” tab and clicking “Power,” then click “Restart/reboot.”
  6. For the MMDVM_HS_DUAL_HAT board with the 14.7456 TXCO like I’m using, you will want to run the following command:
    sudo pistar-mmdvmhshatflash hs_dual_hat
