Hello, I miss a l4/env/errno.h when I try to compile the logserver in l4/pkg/log. I'm using the l4v2-API on i586 May this different on the remote cvs ? Greeting Rudolf Weber ...

on page 57. lipc conditions - use when it's clear that destination thread runs on the same CPU. does this mean scheduler will traverse the per CPU queue and look for idle destination thread?

You have to compile your own version of Hazelnut specifically for the iPaq. The Brutus board is not compatible (the memory layout is different). - Volkmar

L4 on iPAQ
by Dominik Gummel 02 Apr '03

02 Apr '03

Hello, I'm trying to install L4 on the iPAQ (3870). So far, my iPAQ has the "bootldr" bootloader and Linux installed. I tried to load the precompiled hazelnut rc2 evaluation suite for the brutus evaluation board over serial cable to ram (to address 0xC1000000) und jumped to this address (as Volkmar described in nov 2002 on this list). This didn't work. The iPAQ wrote some digits on the serial line and crashed. Has anyone who sucessfully installed L4 on the iPAQ some hints for me? Must I compile my own custom L4 for the iPAQ? Or must I use angelboot (I didn't find docs about it in google)? We need L4 on the iPAQ because we are going to port PERSEUS to it. My part will be the port of Linux 2.4 to L4/ARM (it will be my master thesis).

Hello!

Is it "our" version from CVS? Hmm I just took the newest from apha.gnu.org 0.93. I read that you have an own but I thought that is only needed if you have overlapping modules. > How did you configure Fiasco? Could you supply your configuration > (globalconfig.out)!? Sure. I followed the manual and did a make menuconfig in the build directory. I now also tried with the assertions compiled in but none gets triggered so far.

problems running hello in fiasco
by Fabian Sturm 26 Mar '03

26 Mar '03

Hello! I have a problem running the hello world example on fiasco. I downloaded the latest CVS version from 25.4 of fiasco and compiled it like it is described on the web. Except that the sigma0/rmgr binaries were in l4/bin/x86_586/l4v2 and not directly in l4/bin as described. I then created the following grub entry: title Fiasco, hello world root (hd0,4) kernel=/fiasco/rmgr -sigma0 module=/fiasco/main -nokdb module=/fiasco/sigma0 module=/fiasco/hello When I then boot into it I see some messages of the RMGR but then the system is frozen. Maybe someone knows what I should try next to track this down? Thanks a lot, Fabian Sturm My system is a P3 800Mhz 256MB ram notebook with the Intel i815 chipset. (Vaio vx88) The build environment was Debian Linux 3.0 with gcc 2.95.4. The boot messages were: RMGR: Loading /fiasco/sigma0 RMGR: Loading Kernel fiasco main -nokdb RMGR: check_l4_version 0x00300000 to 0x0044a244 RMGR: detected new_style DD-L4(v2)/Fiasco RMGR: configuring s0: (0x00070000, 0x00096000), start: 0x00070000 RMGR: reserve modules memory range: 0x00200000 to 0x0021053c RMGR: starting kernel /fiasco/main -nokdb proto=0x101ba0 @ 0x00300220 Booting kernel image at 0x302000 entry 0xf0001000 Enabling fully serial nested mode for pic Using the RTC on IRQ 8 (1khz) for scheduling (I hope I don't have introduced errors while copying that down)
