Hi Quectel Support Team,
We are experiencing an issue with some of our EC800MCN modules. After power-on, the affected modules do not return the expected RDY indication. Instead, we receive the following boot log:

The firmware version reported by the module is:

Could you please help us determine the root cause of this behavior and advise on the recommended troubleshooting or corrective action?
Best regards,
