This is a host (i.e. x86) compiler crash. Without additional information (e.g. build log) my guess would be that there's not enough memory on the host.

I guess the same way you run it on ESP32. You'd need to figure the address where the kernel goes and FLASH/PSRAM caches setup. Take [this branch](https://github.com/jcmvbkbc/linux-xtensa/commits/xtensa-6.1-esp32) for a template,...

> the bootloader needs to be rewritten because it uses functions that are only available on the ESP32, not the ESP32-S3 Yeah, it looks like it could use spi_flash_mmap or...
