      SOLVED:

      I found the upload speed setting, and sure enough, that fixed it. Thanks!

      @teastain Thanks for the reply.

      I've tried multiple cables. Some high-end ones. No change.

      The default sketch that ships on the Core was giving me this error, so I wiped with esptool, and same error.

      How do I slow the upload speed?

      Thanks again.

    • Unable to verify flash chip connection

      Hi, everyone. I'm getting the following when I try to upload a sketch to my m5Stack Core Basic:

      Sketch uses 230493 bytes (17%) of program storage space. Maximum is 1310720 bytes.
      Global variables use 20968 bytes (6%) of dynamic memory, leaving 306712 bytes for local variables. Maximum is 327680 bytes.
      esptool.py v4.5.1
      Serial port /dev/cu.usbserial-556E0263581
      Connecting.....
      Chip is ESP32-D0WDQ6-V3 (revision v3.0)
      Features: WiFi, BT, Dual Core, 240MHz, VRef calibration in efuse, Coding Scheme None
      Crystal is 40MHz
      MAC: b0:b2:1c:51:83:80
      Uploading stub...
      Running stub...
      Stub running...
      Changing baud rate to 921600
      Changed.

      A fatal error occurred: Unable to verify flash chip connection (Invalid head of packet (0xE0): Possible serial noise or corruption.).
      Failed uploading: uploading error: exit status 2

      I searched this forum for this, and I'm not optimistic this will be an easy fix, since I don't see anyone else running into this.

      This is just a blank sketch.

      Any thoughts on how to get around this? I'm on a Mac. Thanks!
