Hi, I'm new to this SDK, and I'm facing the error "BFLB LOAD HELP BIN FAIL" when attempting to flash the 'helloworld' example.

I've downloaded both the SDK and the toolchain, installed them, and finally imported the SDK into Eclipse CDT. It seems that I can successfully compile the examples (both 'helloworld' and 'freertos'). However, when I try to flash the 'helloworld' example onto two BL616 devices (two Sipeed M0S modules with docks), I encounter the error: "BFLB LOAD HELP BIN FAIL." The captured log displays the error message along with the corresponding command line used.

I also attempted the flashing with Flashcube GUI but the result is a different error code (google translation):

It seems like the error may be related to a connection issue, although the (USB) serial port appears to be correctly installed in the Windows peripherals.

I already searched between the other issues with similar error, but this not helped me. Might the devices be defective? An sdk issue ? Or am I probably doing something wrong? I'm stuck with this problem, so any suggestions would be greatly appreciated. Thank you.

My bad. I didn't realize that with "boot", windows allocates a new serial port. The flashing operation appear to work correctly now.
