Thank you for providing the firmware for the PH-7 module. I am currently working with the PH-7 (C4-P02) Core Board based on the EG912U GL. However, when I connect the board via USB to my PC, no serial port is detected. I assume that a serial port must appear in order to properly flash the firmware using QFlash_V7.4, yet I have not found any information addressing this issue.
Could you please advise on the proper steps to detect a serial port and subsequently flash the firmware? Any detailed guidance or references to additional documentation would be greatly appreciated.
Hi,@ZCE_DEV
I’ve already sent you the USB driver. After installation, please check whether the corresponding serial port can be recognized. You can use the AT port to upgrade the firmware through the QFLASH tool.
