@jcmvbkbc I think I found the [missing headers](https://github.com/espressif/esp-idf/tree/master/components%2Fxtensa%2Fesp32s3%2Finclude%2Fxtensa%2Fconfig).

I don't think I need to change anything else besides the core variant headers. I'll try to build it and give it a test in QEMU. Please tell me if...

There were problems when compiling Linux, so I don't think it'll work for now.

I'm finally going to come back to this. So from what I understand so far, the Linux kernel was able to be compiled. However, the bootloader needs to be rewritten...

> @zap8600 You're right, AFAIK there is currently no working boot loader for the ESP32 S3. I've been busy with other things(and was somewhat held back by brocken openOCD, having...
