Using OpenBK7231T_App on BK7231 Chip of QFN56 C-3031 Module: Successful Application Guide

Hello, I have a BK7231 module with a 56-pin BK7231 chip on it.
Can I apply OBK to it?
I tried but didn't succeed, thank you!

The BK7231 module (C-3031) information:

Details of this module:


Following the normal flashing steps,
I connected Tx, Rx, Gnd to the USB-TTL device and provided an additional 3.3V power supply.
Then, I turned off and on the power supply,
But it has been unable to enter the flashing state.

When power off and on, the Uart2 prints those messages:

Hello, first of all, just to be sure - have you used your setup (USB to UART dongle, flasher, etc) successfully on other BK7231 devices?

I don't have any other BK7231 devices on hand,
but this USB-TTL is okay. I have used it to flash other devices before.

SMD code is BK7231QN56B, does this belong to BK7231T or BK7231N?

Interesting, a C-Chip BK7231Q chip module. Hadn't spotted this thread yet. You've probably realised by now Q is not supported
