Uploading to SPIFFS: "invalid head of packet" error

[pauldupuyjr]

I can upload and monitor working code in PlatformIO and Arduino IDE (on Windows 11) but can't upload a small data file to a SPIFFS partition on an Unexpected Maker ProS3 (ESP32-S3).

PlatformIO 2.5.5 output from verbose "Upload Filesystem Image":

SPIFFS Upload failed!

In USBDeview, the device shows connected and enabled with COM8 drive letter and Microsoft USB Serial Device driver.

I've tried multiple short USB cables and get the same result on both a Windows 11 Pro 22H2 and Windows 10 Pro 21H2 computer.

Thanks in advance for your help.

I'm experiencing the exact same error with Unexpected Maker TinyS3 and Feather S3 boards.

I've attached a trace of the error.

We've narrowed down the issue to the partition tables and I've opened issues in the appropriate GitHub repos:
