EG915N-EU QuecPython flash problem

QuecPython
1

Hello,
I try to flash QuecPython image on Quectel EG15N-EUAG. The device is with the original AT firmware, I want to convert it to Python enabled firmware. I fail to do the update both with FOTA and with QFlasher/QPycom.

  1. On Windows 10 installed the latest driver QuecPython_USB_Driver_Win10_ASR.

  2. I see 3 COM ports: Quectel USB AT Port (COM7), Quectel USB Diag Port(COM4), Quectel USB NMEA Port (COM6)

  3. Test QFlash 7.3 by updating with ordinary firmware: EG915NEUAGR03A16M16_01.200.01.200.zip. It works - the device is updated, I can see that it boots with the new version.

  4. Download latest QuecPython for EG915N: QPY_OCPU_V0001_EG915N_EAAC_FW.bin

  5. Neither Pycom nor QFlash work. PyCom 3.6 hangs for a 2-3 min and exits with status failed. QFlash starts some process, several log messages blink quickly on the status bar. But after 2-3 seconds displays a red messge that Download failed.

hi,defun
May I ask if the module you use is EG915NEUAG? From your description, the python firmware you burned is QPY_OCPU_V0001_EG915N_EAAC_FW.bin, do I understand?
The problem may be caused by inconsistency with the firmware model and module model

Hi,
Yes the module is EG915NEUAG. This is the exact version, return from AT+QGMR

AT+QGMR
EG915NEUAGR03A16M16_01.200.01.200

  • I go to QuecPython downlod site: Resources Download | QuecPython
  • Select the checkbox EG915, EG915N Series
  • The only option for download that I see with that selection is QPY_OCPU_V0001_EG915N_EAAC_FW

Thank you very much! My email is: ptodorov@quint8.net

Is it possible to update to QuecPython using FOTA from stock AT firmware? Or the update is possible only with direct USB connection?

I have emailed it to you, please try it
Firmware needs to be downloaded via USB

I updated the module successfully and it works. Thank you very much for your support!
