I’m sorry to bother, again… But I keep getting problems hope you can give me some advice.
I’m trying to test out L4re +L4Linux on X86 and ARM i.MX6. I downloaded the newest l4re-snapshot-2006082114. I built Fiasco with Intel Pentium Pro and Virtualization (did not change anything else). I built L4re with Pentium Pro type CPU (everything else are default settings). Then I built L4Linux with the L4re builddir. I turned off 64-bit kernel, CPU selected Pentium-Pro, turned off most of the settings as the warning instructed.
These are the settings of L4Linux that I enabled:
Processor type and features:
- DMA memory allocation support
- Processor feature human-readable name
- Fast CPU feature tests
- Support for extended X86 platform
- Single-depth WCHAN output
- High memory support is OFF
- Enable bounce buffers
- X86 architectural random number generator
- Enable seccomp to safety compute untrusted bytecode
- Enable the LDT
Power Management and ACPI options:
- Suspend to RAM and standby
- device power management core functionality
- CPU Frequency scaling is OFF
Bus Options:
- PCI support
- PCI access mode is Direct
That's ok. You can also use one of the defconfigs, e.g. x86_32-mp_vPCI_defconfig.
I was able to compile all three parts and build both iso image (for vmware fusion on macOS) and qemu simulator. I first tested hello, hello-cfg, hello-shared, frame buffer-example-x86, all of those works as expected.
Ok, good.
However when I tried to build L4Linux-basic and L4Linux-mag-x86. Not of them works.
for L4Linux-mag-x86 the system shows a diagram “system is booting” then hang forever.
In such a case it is essential to have the serial output to see what's going on as we won't see anything on the graphical screen in this case.
for L4Linux-basic the image boot but freeze soon. The screen shows:

That actually looks good. It finished booting as it is supposed to do. Is input not working, i.e. pressing enter?
