Hi Bean,

Please find the attached boot logs,

I will check internally.
Could you login in the debug uart of the modem?
The username is root.
You might see quectel-ID and please provide it to me and I could provide you the passwd.

29

Please check it and provide the waveform.

If you login in the modem, you could use the “dmesg” cmd to provide the kernel log for the Quectel modem.

When I give root, it always goes for password; it is not showing ID Bean

If you could not see the Quectel ID, just try the passwd as:
Quectel123 or onelinux123 or Quectel
