Hi guys, Thanks for the suggestion.
I followed your instructions and tried updating the driver manually. However, even after selecting “USB Serial Device” from the list, it still shows up as “USB JTAG/serial debug unit” in Device Manager.
I also tried flashing the official factory firmware using EspRFTestTool, following Seeed’s guide. I held the BOOT button while connecting the board to USB, and then attempted to load the official .bin file but unfortunately I still get this error.
ERROR:Write timeout
WARNING:Sync fail…
At this point, I’ve tried multiple cables, different USB ports, and even different PCs, I updated the Driver per @nblanch 's suggestion but the issue remains.
Any other ideas would be greatly appreciated!
