Hello,
I'm a l4 beginner. So I have 2 questions to standard issues (guess) .
1.:
I followed the Building & Using Fiasco html to the debugging point. - I removed the -nowait Kerneloption - I edited the .gdbinit file with > file ../build_x862/kernel.image (current compiled kernel) > target remote /dev/ttyS0 (debugging on COM1) - When fiasco comes up, I start gdb and immediatly after that my testmachine reboots, when it comes back up everytime i type c in my host debugger it reboots again. - When I use > file ../build_x86/kernel.image, a kernelimage I built some time ago, gdb says > 0x00000000 in ?? () and again, when I press c it reboots. - There was no KDB::Init- Message at all. - I expected the kernel to continue normal operation like with the "nowait" option after pressing c in the debugger..., Am I wrong ? - Kernelconfiguration in globalconfig.out - My menu.lst: 38 title fiasco 39 kernel $(P)/bootstrap 40 modaddr 0x02000000 41 module $(PF)/fiasco-o -comport 1 -comspeed 115200 42 module $(P)/sigma0 43 module $(P)/roottask
2.:
My testmachine is an Advantech PCM 5820. It shares the video mem with normal RAM. When I boot up DOpE I get several error messages (see file error.txt) The following lines put L4io about my video:
io | 40800000-40ffffff : Cyrix Corporation 5530 Video [Kahlua] io | WARNING: Cannot handle memory 40800000-40ffffff for device 1078:0104
So I guess it couldn't get the RAM it wanted to ?
When I tried to boot up with L4Con these messages appeared :
con | Mapping I/O video mem 40800000 => 00400000+000000 [4096kB] con | [8.2] l4con/server/src/con_hw/iomem.c:61:map_io_mem(): con | I/O video memory address is below 2GB (0x80000000), con | don't know how to map it as device super I/O page.
So I guess my video mem is mapped to 0x00400000 via Hardware ?
DM_Phys has allocated this AREA (0x00400000-0x00800000). So I tried to reserve this area with its --reserve option. Plus I dissabled L4log for the moment because it was mapped into the AREA by the roottask. But it didn't help, maybe already sigma0 has this area, so i cannot be remapped ?!
So I read a little along the source of sigma0, but didn't find anything yet...
Hopefully you can help me ?!
Thanks, Marcus
