Porting i.MX6 FEC ethernet device driver to L4Linux (l4re-snapshot-2014092821)
by Mahdi Aichouch 29 Oct '15

Hello, Starting from a previous work [1] , I ported the i.MX6 FEC ethernet device driver to L4Linux (l4re-snapshot-2014092821). There is no compilation error, but when I tested on the Freescale i.MX6 Sabre SDB, it seems that L4Linux does not start the device. Below are the boot messages of L4 Fiasco + L4Linux. Does someone have an idea of what might be missing or wrong. To reproduce the test case using l4re-snapshot-2014092821, all configuration files and patches are given below. Thank you very much in advance.

Sharing one ethernet network device between two L4Linux instances
by Mahdi Aichouch 27 Oct '15

27 Oct '15

Hello, I was able to run two L4linux instances on top of L4 Fiasco OC using a Qemu emulator of a versatile express-a9 board . I would like to make these two instances share one ethernet network device. I would like also to switch between the two L4Linux shell, because in Qemu only one shell is accessible. I followed this guide[1] to connect two L4Linux instances using "l4shmnet", and this thread [2] to get access to the shell when testing on Qemu. However, the "l4shmnet" is not working correctly, both L4Linux display this message: shmns: Requesting, Shmsize 1024 Kbytes shmns: Failed to establish communication Could someone help me building such a working configuration. Is it possible to share a working Qemu command with the right option for the network? This is my Qemu command $> qemu-system-arm -cpu cortex-a9 -M vexpress-a9 -smp 1 -no-reboot -m 1024M -kernel bin/arm_armv7a/bootstrap_L4Linux_ARM.elf -nographic -net nic,model=lan9118 -net user Is it also possible to share a working lua configuration file? This is my lua l4lx.cfg file: -- vim:set ft=lua: local lxname = "vmlinuz"; if L4.Info.arch() == "arm" then lxname = "vmlinuz.arm"; end local shmns = L4.default_loader:create_namespace({ shm = "placeholder" }); L4.default_loader:start( { { ldr_flags = L4.Ldr_flags.eager_map }, caps = { log = L4.Env.log:m("rws"), }, l4re_dbg = L4.Dbg.Warn, log = { "l4linux", "yellow" }, shmns = shmns:mode("rw"), }, "rom/" .. lxname ..

Hi, Are there any relative complex and non-trivial applications on top of Fiasco and l4Re? If so, where can I get the source code? Thanks a lot. Yuxin

make clean (really!)
by ba_f 12 Oct '15

12 Oct '15

Hello, i try to build the newest snapshot while still having an old one on the disk. Unfortunately, 'make setup' crashes when looking for Cross Tools. Anyway, i don't think it has something to do with the new snapshot, but some hidden setup files storing my old config. Because, when i rename my old snapshot and then try to rebuild it, it crashes as well. So, how do i make the setup really clean? 'make clean' seems not enough, since it still knows some old configs. Where are those hidden files, and how to remove them? Thanks.
