new m5stack: Failed to write to target RAM (result was 01070000)



  • hello!
    just got a new (first) m5stack, and am stuck at:

    • Serial port /dev/cu.SLAB_USBtoUART
      Connecting........__
      Chip is ESP32D0WDQ6 (revision 1)
      Features: WiFi, BT, Dual Core, 240MHz, VRef calibration in efuse, Coding Scheme None
      MAC: 24:6f:28:8f:d1:54
      Uploading stub...
      A fatal error occurred: Failed to write to target RAM (result was 01070000)

    this happens with M5burner as well as Arduino configured with the ESP32 board specs. MacOS10.14.6 with the USB driver. tried all baud rates with the same result. (NB: had to un-quarantine M5burner with xattr, even though copied in /Applications).

    any thoughts?
