Custom board shows Error and reset loop after "sucessfull" flashing

[Knochi]

So i build a board with an ESP32-S3-Wroom-2 module.

Boot strapping pins
GPIO0 - testpoint/button
GPIO46 - NC

Arduino IDE Setup
Arduino IDE 1.8.19
official espressif "ESP32 Arduino" 2.0.11
the only things i changed was CDC on boot and reduced speed to 115200

Arduino IDE board settings

after resetting the board i can see this on COM6

Googling that 'assert failed' seems to indicate you selected a larger amount of flash than your board has. Can you check that?

[lbernstone]

ESP32-S3-WROOM-2 should use OPI flash (and OPI PSRAM if 8MB).

[Knochi]

Module is marked with M0M32R8V which is the 32 MB (Octal SPI) version with 8MB (Octal SPI) PSRAM

I changed the settings accordingly and now it works! Thanks!
