Hello,
I’m trying to flash the ST67W611 Wi-Fi module directly through UART, without using the NUCLEO host board.
For hardware setup, I soldered simple tactile switches and 0.1 µF capacitors on the CHIP_EN and BOOT pins.
When powering up:
I press both switches to pull CHIP_EN and BOOT low (to GND).
Then I release the BOOT button so that the pin is pulled up to 3.3 V through a 10 kΩ resistor.
Finally, I release the CHIP_EN button, which is also pulled up to 3.3 V through another 10 kΩ resistor.
After this sequence, I run the following command in Windows PowerShell, but the handshake fails:
PS D:\Backup\STM32_Project\ST67W611M1\Resource\x-cube-st67w61\Projects\ST67W6X_Utilities\Binaries> QConn_Flash\QConn_Flash_Cmd.exe --port COM8 --config NCP_Binaries\mission_t02_flash_prog_cfg.ini --efuse=NCP_Binaries\efusedata.bin
Here is the full output log:

Has anyone experienced the same issue or knows how to handle this handshake failure when flashing ST67W611 directly over UART?
Any suggestions for timing, baud rate, or pin control would be greatly appreciated.
