espflash detects wrong flash size

[brookman]

I have an esp-c3-32s-kit-v1.0 (version a) see PDF page 11 .

When flashing with espflash it prints this:

Chip type:         esp32c3 (revision v0.3)
Crystal frequency: 40MHz
Flash size:        2MB
Features:          WiFi, BLE
MAC address:       [redacted]
App/part. size:    1,071,792/2,031,616 bytes, 52.76%

[2024-02-11T09:46:00Z INFO ] Flashing has completed!

It says 2MB, however the board is supposed to have 4MB.

I also have the issue that I can only flash and run it by this process:

• unplug the USB cable
• press and hold both buttons
• plug in the USB
• release the buttons
• flash
• unplug the USB cable
• plug in the USB

This only started happening recently. Before I could flash it without this workaround. I suspect something went wrong with the flash size or layout at some point.

The datasheet for the board also says there is a 2MB verison. Could you check what esptool.py detects?

Dear @MabezDev, I checked again and it is indeed the 2MB version. 🫢
I'm terribly sorry!
