@jiewei.ye , I need an apology to you. I was eager to answer about the port and I did it wrong. Thanks for your help. I was able to upload FW via XMOS port. That part is solved.
However, I am still not able to upload FW from ESPHome (Home Assistant).
Manual reads “Connect the XIAO ESP32S3 to your PC via a USB Type-C cable.”. So, this is now the other USB port as before. On the very top from the picture above. When connected, it reads COM 5. In Zadig, “USB Serial” driver is used. If I try “WinUSB”, then the device will not show up in the ports list or in the list of available devices in ESPHome.
Attempts to upload FW from ESPHome to device “USB JTAG/serial debug unit (COM5) - paired” fail with a message “Failed to initialize. Try resetting your device or holding the BOOT button while selecting your serial port until it starts preparing the installation.”. Following instructions from the message gives the same results. Before the fail message appears, device sounds with scratch sounds a few times.
Is the way I am doing it correct?
Is there a better way to upload FW to the XIAO ESP?
Thanks a lot!
