C3 rev correction

[lure23]

This is the only place in the awesome book that had me doubting.. Perhaps what is written as "revision 3" should be "revision 0.3"?

In the book itself, this line lists a C3 revision as "0.3".

I have a 0.4:

$ cargo espflash board-info
[2024-01-07T21:06:35Z INFO ] Serial port: '/dev/ttyUSB0'
[2024-01-07T21:06:35Z INFO ] Connecting...
[2024-01-07T21:06:35Z INFO ] Using flash stub
Chip type:         esp32c3 (revision v0.4)       <<-----
Crystal frequency: 40MHz
[...]

Please verify. I am not in the position to know, where the JTAG became built-in, but I do hope my 0.4 board has it.

Found a source to back up my gut feel:

Debugging through the USB interface implemented in ESP32-C3 requires to have a chip with revision 0.3 or newer.

Lgtm! Thanks for the clarification. You are completely right, 0.3 is the correct way to name the version.
