Hi Alex,
Are you able to make your images available for me to download? Has this worked
before for you and has recently stopped working? Do the images work in Qemu
(you may have to rebuild with -DSIMULATION=ON)? We do most of our development
using PXELINUX with the following configuration:
SERIAL 0 115200
default sel4
label sel4
kernel mboot.c32
append sel4kernel --- sel4rootserver
Kind regards,
Kent

Subject: [seL4] Booting seL4test on x86 hardware
Hello,
We are having issues being able to get the seL4test userland image to boot on
x86 hardware. We have attempted to boot with syslinux off a USB, with PXELINUX,
and with grub and see the same userland image loading issue across boot methods.
Build steps:
- Following https://docs.sel4.systems/Hardware/IA32
- Using “-DPLATFORM=x86_64”
o Does not appear to boot (no serial output)
- Using “-DPLATFORM=ia32”
o Kernel boots but is unable to load userland image
The manifest commit hash is:
01c11cfcd881c1da5b7520162fae40f6eae1c16b
Hardware:
- DELL Optiplex 980 with an Intel Core i7 860 processor
We are seeing the following serial output:
