Perhaps the script needs to be modified slightly to match the latest image. I used Latest Debian 11 (bullseye) from "debian-11.3.0-mipsel-netinst.iso" as a base.
- Run
build.sh, it will download cd image from debian server, build qcow virtual hard disk image and run debian installer.
- Ready to use. Run
run.shthen raise up debian 11 mipsel on qemu!
ssh localhost -p 2222Have fun!
It's completely off-topic, and probably a strange nerd story :)
I am developing a .NET library for video capture. I thought this library should be tested in a variety of environments in order to be truly multi-platform. So, I was looking for a somewhat minor environment in which .NET (actually mono) would work, and "Imagination Creator Ci20" was found.
The Ci20 is a MIPS 32-bit architecture that is still barely available and can operate as a USB host. It seemed feasible to perform video capture via V4L2, supporting USB Video Class. So, we quickly obtained this board and found that only supports Debian 8 (jessie) and Moreover, it seemed to have been removed from the supported list as a beta release.
After some information and trial and error, I succeeded in applying the latest binary packages for Debian 8. Apparently there is still an eMMC access bug in the kernel, which causes the system to stop with UBIFS-derived panic when I/O is under high load. Also, I need a relatively new version of Clang, but Debian 8 only has an older version, and If I try to build it on my own, I get the above panic and am out of luck.
I wish I could fix this kernel fundamentally, but unfortunately, I do not have that much knowledge. So I have decided to take other steps.
I realized that building the code on a modern Debian 11 using qemu's mipsel emulation would work fine, so I created this script by trial and error from my sources.
