Troubleshooting Checklist
Before contacting Zymbit with troubleshooting related questions, please read through the following troubleshooting checklist.
- Power supply. Most of the problems we see are from a poor power source. Start with a good power supply from the PI foundation or Canakit, not a phone charger. The recommended power for the PI4 is 5V and 3 amps. For a PI5, the recommended power supply should provide 5V, 5 amps.
- (For Zymkey, HSM4, HSM6) I2C enabled. Double check that you have enabled the I2C bus. An easy way to check is “ls -l /dev/i2c-1”. If /dev/i2c-1 exists, the I2C bus is enabled.
- apt update and upgrade. Be sure that your software is up to date.
- Installation. The curl script will reboot your system once completed. After the reboot, the blue LED on your Zymbit device should blink once every 3 seconds. You must get to this step before proceeding to encryption, etc.
