Hi,
I want to build linux kernel with minimal features from sources and simple file system to run on Juno.
Please let me know from where I can download linux kernel sources and simple root file system ?
I tried building Linaro kernel base for Juno and facing issue while running during the fixed map setup.
I wanted to turn off this fixed map and most of peripherals and build my own customized Linux kernel in order to run on my Hypervisor.
Please advice from where I can get Linux source code and also build simple file system ?
Thanks
Hi armdev,
The kernel sources we recommend using for Juno are those hosted here: http://releases.linaro.org/latest/members/arm/platforms
Either the LSK or Tracking kernel. Linaro also provide a simple busybox filesystem.
If you are customising the setup and encountering problems, obviously this as an "open source engineering activity" and not something we can officially support you with. However if you can be more specific about exactly what you are doing and what goes wrong, someone may be able to offer some helpful comments.

I want to disable fixed map feature from linux kernel as I understand it is for UEFI compatibility and as I am not using UEFI I am facing issues.
Please let me know how I can achieve it ?
Have you tried editing the device tree to reduce the memory available to Linux? This might provide a workaround.
Try to run mainline defconfig to check if it's an issue with old kernel.
Sometimes it could be fixed in mainline but not in LSK/tracking kernel
since it is based on older kernel.
