I followed instructions for updating firmware and rtl8720 shown at
Using Windows Powershell
ran ambd_flash_tool.exe erase >>success!
ran ambd_flash_tool.exe flash >>success!
downloaded 20210519-seeed-ambd-firmware-rpc-v2.1.3.zip
ambd_flash_tool.exe flash -d c:\rtl8720 >>success!
but in WIO LCD, it says “Burn RTL8720 fw”
what did I do wrong?
thanks
