Problem uploading FFAT partition to ESP32 (solved)

[wrybread]

I have a project that used to work for me, but that I now can't upload. I wonder if anyone has any advice?

The project uses a FFAT partition, and I have the files that will go to the FFAT files in my script's /data partition. Here's a screenshot of my settings in the Arduino IDE:

However when I select ESP32 Sketch Data Upload, I get the error:

"SPIFFS Error: partition size could not be found!"

Everything works fine if I change the partition type to SPIFFS (Tools -> Parititon Scheme -> Default 4mb with SPIFFS), but I can't get FFAT working.

After changing the partition type to FFAT (Tools -> Partition Scheme -> 4mb with FFAT) I upload my script, then do the sketch data upload, and every time I get that error.

Looking at my partition table for FFAT (ffat.csv) it looks like this:

# Name,   Type, SubType, Offset,  Size, Flags
nvs,      data, nvs,     0x9000,  0x5000,
otadata,  data, ota,     0xe000,  0x2000,
app0,     app,  ota_0,   0x10000, 0x200000,
app1,     app,  ota_1,   0x210000,0x200000,
ffat,     data, fat,     0x410000,0xBF0000,
# to create/use ffat, see https://github.com/marcmerlin/esp32_fatfsimage

I wonder if I'm forgetting some step I need to do before uploading a FFAT partition?

Any ideas by chance?

Oops, please disregard, the data upload tool only works with SPIFFS.
