ST67W611M1 QConn_Flash failure
Dear all,
I have designed a custom board using the STM32H563ZIT6 as the host MCU and the ST67W611M1 as the NCP.
As part of the initial bring-up, I am attempting to flash the ST67W611M1 using the QConn_Flash_Cmd-ubuntu tool in standalone mode. For this, I have connected a USB-to-TTL converter directly to the NCP UART interface.
The BOOT and CHIP_EN pins of the ST67 are controlled by the host MCU, which toggles them in the required sequence to place the NCP into UART (flash) mode (see below code). I use the same sequence given in the NCP_Loader Example.
if (flash)
{
LL_GPIO_SetOutputPin(BOOT_GPIO_Port, BOOT_Pin);
}
else
{
LL_GPIO_ResetOutputPin(BOOT_GPIO_Port, BOOT_Pin);
}
/* RESET NCP CHIP */
LL_GPIO_ResetOutputPin(CHIP_EN_GPIO_Port, CHIP_EN_Pin);
HAL_Delay(100);
LL_GPIO_SetOutputPin(CHIP_EN_GPIO_Port, CHIP_EN_Pin);
if (flash)
{
/* CLEAR BOOT */
HAL_Delay(100);
LL_GPIO_ResetOutputPin(BOOT_GPIO_Port, BOOT_Pin);
}I verified the BOOT and CHIP_EN signals on an oscilloscope, and they appear to follow the expected sequence. However, when I run the QConn_Flash_Cmd-ubuntu tool to flash the Mission 1 or 2 binary, the process fails during the handshake phase with the NCP. The tool reports the following output:
❯ ./QConn_Flash/QConn_Flash_Cmd-ubuntu --port /dev/ttyUSB0 --config ./NCP_Binaries/mission_t02_flash_prog_cfg.ini --efuse NCP_Binaries/efusedata.bin
