enable to flash OEM firmware after updating with Logicrom firware #6

Closed swapniltx closed 9 months ago

swapniltx commented 9 months ago

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?

May I know what information are you trying to check? You can email us separately for website related issues.

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

Connect USB_BOOT with VDD_EXT/1.8V
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.
