boot fail (illegal instruction)

[FransM]

First try to boot linux on esp32-s3 (ESP32-S3-WROOM-1 N16R8) fails. build was done with rebuild-esp32s3-linux.sh

Seems to be address related. At the end of the boot it says: ptr = 0x42830000 ptr = 0x42b30000 Guru Meditation Error: Core 0 panic'ed (IllegalInstruction). Exception was unhandled. Memory dump at 0x4282fffc: d5557555 ffffffff ffffffff So apparently there is nothing at the first ptr address

Rebooting...

build was done with rebuild-esp32s3-linux.sh

It's outdated and is likely broken by now. Please try rebuild-esp32s3-linux-wifi.sh instead.

I have rebuild with rebuild-esp32s3-linux-wifi.sh and flashed it and it works!

Seems indeed that the non wifi version is broken; maybe some code in the non-wifi version that wants to start or access the wifi core.

I'm also not sure if the non-s3 version still works. tried that first, of course on an esp32 (ESP32-WROOM-32 on a DOIT ESP32 DevKit V1 Wi-Fi Development Board ) but that was not successful. I seem to recall that failed because upon booting the system complained that there was no PSRAM

Leaving this for you to decide on closing now or keeping open until the non wifi version is fixed or removed.

I've rebuilt and re-flashed it just now, works for me on the freenove esp32-wrover-dev board with 4M PSRAM.

Leaving this for you to decide on closing now or keeping open until the non wifi version is fixed or removed.

Thanks. I'll take a closer look in a few days.
