Unable to verify firmware updater utility for MKR1010

[thomas_simpson68]

I'm having problems configuring the MKR1010 for the IOT cloud, so I attempted to update the firmware version to the latest revision. I followed the instructions I found on this forum and downloaded the arduino-nightly-windows .zip file, unzipped the files, and ran the arduino.exe file. The library update ran without errors, so I ran the firmware updater utility. The utility fails to verify, so I am unable to update the firmware. Is this a known error? How should I proceed? This is getting very frustrating, please help!

Here is the error message:

Hi @thomas_simpson68. The error is caused by you having the wrong board selected from the Arduino IDE's Tools > Board menu. You need to select Tools > Board > Arduino SAMD (32-bits ARM Cortex-M0+) Boards > Arduino MKR WiFi 1010 and then try uploading the firmware updater sketch again.

---

If you don't see that menu selection, that means you don't have the Arduino SAMD Boards platform installed. You can install it by following these instructions:

• Tools > Board > Boards Manager
• Wait for the update to finish.
• Scroll down through the list of available boards platforms until you see "Arduino SAMD Boards (32-bits ARM Cortex-M0+)". Click on it.
• Click the "Install" button.
• Wait for the installation to finish.
• Click the "Close" button.

After doing that, you'll be able to select Tools > Board > Arduino SAMD (32-bits ARM Cortex-M0+) Boards > Arduino MKR WiFi 1010 and upload the firmware updater sketch to your MKR WiFi 1010.

That was the problem. Update complete. Thanks! I missed that step.

You're welcome. I'm glad to hear it's working now. Enjoy!
