Can't run this linux build on a ESP32S3 N16R8

[arashsaifi]

Hey so I made a sort of a diy esp32 board using this tutorial -> https://www.youtube.com/watch?v=tQ0dL_9M1wI&pp=ygULZGl5IGVzcCBcMzI%3D

I was successful in my attempt and I could see this as a COM serial port in my terminal.

I built the linux for it and flashed it (accordingly for the USB serial to work with some modification to a file in the etc partition)

The problem is that when I try to use the "idf.py monitor" command it gets stuck at the following line.

linux ptr = 0x42120000
vectors ptr = 0x4037c000

am I missing something or is this a bug which needs to be fixed

am I missing something or is this a bug which needs to be fixed

I don't know. I don't have N16R8, and by default the build is configured for N8R8. I'm not sure what happens if you flash it into N16R8 without first reconfiguring it, I imagine that there may be issues with FLASH/PSRAM voltage.

[arashsaifi]

That's what I thought and then went ahead and tried it with N8R8 and had the same results. The output on your wiki shows that it boots to a console but mine is stucked at the first two lines.

Can you share the images that were flashed? Specifically build/build-buildroot-esp32s3/images/*

[arashsaifi]

Sure, currently I am outside once I reach home I'll upload them

build.tar.gz
These were the files generated by the build script

[jcmvbkbc]

These were the files generated by the build script
I built the linux for it and flashed it (accordingly for the USB serial to work with some modification to a file in the etc partition)

There's no /etc/cmdline in the etc.jffs2 from that archive, so default console is on the UART. And if I flash the kernel and etc from the archive to a devkit board I get the expected kernel boot log.
So I wonder what modifications exactly did you do?

[arashsaifi]

I might have done something wrong. Can you send me your image with the /etc/cmdline then I can test that out.

etc.jffs2.txt

Also while testing it I've noticed that the jffs2 parser has been ignoring the first file on the file system, which happened to be the cmdline. I've pushed a fix here: jcmvbkbc/esp-hosted@ceab9c2
I made sure that cmdline is not the first file in the attached image, but if you build your own etc.jffs2 with that file, please also update the bootloader.

[arashsaifi]

Okay, I will try it as soon as I reach home

I changed that file with your etc and now it shows a bunch of output but is stuck at some other stage. Here is the output of my board.

It's about the time when the kernel should start accessing flash. Let me take a look at that.

[arashsaifi]

Any luck ?

Could you try flashing the following kernel image and post its output:
xipImage.txt
That kernel has debug logging in the flash partition table parser and ipc code.
