I need some help to re flash my A9G module as it do not respond over over UART1 (TX1/TX2), I already did burn weeks ago a micropython firmware on the module. I think yesterday i used the usb 2serial at 5v not 3v3 and perhaps I broke the UART1. ?? the point is that only host tx/rx port works with coolwatcher/or fw burner,

I had both windows CoolWatcher burner / ubuntu toolchain enviroments ready but im not sure where output directory.

I need some help to re flash my A9G module as it do not respond over over UART1 (TX1/TX2) thanks in advance.

Thanks Pulkin! my module after a successful Host UART does no respond at UART1. any way to compile a new .lod firmware redirecting repl to lets say IO2/IO3 as I do not need CTS/RT or other at IO20-IO30? Im from Argentina an have a new pudding take like 2 months to more.

thanks in advance.

You may try first UART2. Otherwise one needs to implement software UART.

Thanks, but UART2 doesnt connected to GPS port? actual micropython port does support SW UARTs in other pins?

Nope.
