advice about esp32-c6 pcb design

[rotebd]

I'm designing a pcb to use a esp32-c6-wroom ; I tested my code on a dev-board and it works fine.

I started to do a simple breakout board to bake the module on a pcb ang get each of it's pins. I connected 3,3v and EN to a power supply v+, gnd to gnd, usb_d+ to io13, usb_d- to io 12 : good news, it seems to connect and gets a com port.

Bad news (would not write here if everything was working), it seems to continually reboot : I did read the module's datasheet (https://espressif.com/documentation/esp ... eet_en.pdf) section 8 (peripheral schematics) and would like to have advice about what to add to make it work and keep the connection alive.

Bootstrapping pins? I don't what else could hepl.

Thanks in advance for any advice ; will give infos if needed (just ask).

It does that when there's no valid code in flash. Pull GPIO9 low, reboot the chip, upload new code and reboot it again and it should work.
