How to USB-C cable?

[dingo35]

First of all: big thanks for this great project, love the hardware, love the software.

I have customized the firmware, and now finally got overconfident and messed up the firmware. I always used the wifi /update method, so as I understand ota1 now has my bricked firwmare, and ota0 still is supposed to have the original firmware.

My first problem is the USB-C connection: I see a 6 pin header marked P2, is this the header the USB-ftdi cable has to be connected to? What are the specs of the header-pins, or is there a standardized USB-cable that I can buy that has the header already in place?

I understand I can clear the ota partition with the esptool: python esptool.py --chip esp32 --port "COM7" --before default_reset --after hard_reset erase_region 0xe000 0x2000

Will this clear the ota0 (usb-programmable) partition or the ota1 (wifi /update partition) ?

Big thanks for your support!
