I have updated the firmware for EC200U as per document for experimenting with logicrom firmware and system. I am not getting device information on waybyte website. Now I wanted to flash OEM firmware to the same module. I am unable to do so using QFlash or Logicrom flasher.

  • With QFlash Unisoc USB serial port selected it fails with timeout.
  • With Logicrom flasher I do not get option for port.

Can you please suggest a solution or point me towards any document?

You need to put device in flash mode again. There are two ways to do that:

  1. Connect USB_BOOT with VDD_EXT/1.8V
  2. Send force boot AT command: AT^FORCEDNLD

You can send at command from serial or USB AT port.

Can you please suggest a solution or point me towards any document?

We will update our documentation for this topic.
