Hi all,
do you know how to flash the ESP8685­-WROOM­-03 without using testpad IO9?
JTAG signals are disabled and is not possible to program using ESP-PROG.

Thanks

You could try to use the built-in USB-serial-JTAG converter.

I have developed a clip-on device for flashing this chip, which can connect to a standard usb-serial device. It includes a push button for boot mode.
If you're interested I can sell you one for $20, let me know.
