Hi Everyone,
I am trying to flash image on QCA4020 through USB. I have followed the guide to install J34 Jumper on pins 1-2 to put the chip in EDL mode. When I connect micro USB cable to J6 the device manager shows device as QUSB_BULK. Does this means the device driver has not been installed correctly? Thank you.
Regards
Yifan

QUSB_BULK error is due to corrupted USB driver, you need to reinstalled the USB driver.
However, we suggest customers to follow JTAG flashing instructions.
Thank you
