Can't seem to flash the AI Thinker Audio Dev Board

[iroth]

On Mac, installed the latest IDF, but can't seem to connect to the ESP32 (I see the port as: /dev/cu.SLAB_USBtoUART). I get this error:
A fatal error occurred: Failed to connect to ESP32: Invalid head of packet (0x00)
anybody knows what might be wrong (I tried to change the baud to 115200):
idf.py -p /dev/cu.SLAB_USBtoUART -b 115200 flash
still the same error
I have the v4.1 of the ESP-IDF
