Hi, Martin
Sorry for late answer. I was very busy because of my company.

Hi, Martin
Great to see again :-)
Yeah :-)
The reason of that I disabled 'L4_CLK_NOOP' is as below. When I added SD/MMC device driver and etc options in menuconfig, I met error message as below.
So, in order to solve this problem, I modified source code at first and amended Kconfig file thereafter.
Ok, that makes sense.
What about your progress with fiasco?
I've succeeded in loading two L4Linux and running MPI program in each. And I've succeeded in getting Ethernet which can connect external network.
Did you manage to get everything running you need? Interesting to hear that SD/MMC is running on your system.
But I've failed in getting SD/MMC despite loading MMC driver and registering MMC device in IO server. I guess that there is problems in mach-setup.c (about PHY?) like previous a problem of Ethernet. Somehow I guess that some modification in mach-setup.c is needed.
I use it only temporary for booting U-Boot and will be removed later.
Me,too I can't use SD card in L4 Linux yet.
What I am missing is support for NAND and NOR (via SPI), but next week I will start this task.
Currently I am stumbling with IPC. I have about 12 different Linux processes communicating via Unix Sockets in each direction. Now I want to have 6 on one l4linux an 6 on another l4linux. I got it working by using the l4shmnet driver and TCP-Sockets, but IP is not allowed and the Linux IP-Stack must be removed, so I have to use something else. Unfortunately I don't know of any ready-to-use alternative, so I have to do it on my own.
I haven't try to do IPC in two L4 Linux. Did you make sure you enable it as below?
