Hi to all,
I made a custom pcb for the AM02 module with recommended circuit. I want to make another PCB but not including Usb port/user reset button and circuitry and using an FT232 externally.
On my first PCB I put external header pins for GND CTS 5VTXD RXD DTR but when I try to upload code I got the “Initialising bootloader.
Unhandled error: Timed out waiting for Bootloader response.” error with any combination of Reset and User button.
Using the usb and CP2102 chip normaly, I am able to upload code without pressing any buttons.
What is the minimal configuration for flashing an AM02 with an USB UART FT232 based? Did someone make a PCB based on a AM0x module AND not using CP2102/User/Reset buttons ?
