[Ql-Users] Errors with uQLx on Raspberry Pi
Hi All, Is anyone able to assit or at least start me off on a general direction. I am trying to get the uQLx running on a slow (MK.all takes 160 seconds), memory restricted Raspberry Pi with the Armel architecture. Following Javier's instructions from a message sent 10:17 27/11/2009 I edited the config file to the gcc version I was using and commented out the line in unixstuff.c for RTOP. I used gcc 4.1.3 although 4.4 gives an identical error. The install appears to run without throwing up errors although there are plenty of warnings. When I try to start the emulator, the outline of the QL screen briefly flashes up on screen before I get the followinf error message pi@raspberrypi:~/bin$ ./qm problem, stat failed : No such file or directory - MountPoint /dev/fd0 for device FLP1_ may not be accessible *** QL Emulator v0.81 *** release 2010-02-25 Terminate on signal 11 This may be due to an internal error, a feature not emulated or an 68000 exception that typically occurs only when QDOS is unrecoverably out of control FATAL error, PC may not be displayed correctly DebugInfo: PC=16c, code=adc7, SupervisorMode: yes USP=0 SSp=3 A7=3 Register Dump: Dn An 0 0 0 1 0 0 2 0 0 3 0 0 4 0 0 5 0 0 6 0 0 7 0 3 pi@raspberrypi:~/bin$ Regards John ___ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm

Re: [Ql-Users] Errors with uQLx on Raspberry Pi
John, if you have defined USE_VM, be aware that ARM-Linux uses a signal stack different from that of x86 Linux. I don't have the sources at hand here, but it should be within vm_linux.c where the signal handler picks up information from the sigcontext in order to find where an instruction that needs patching occured. Linux x86 has the offending address in a different field than Linux ARM. Will try and come back to you with more details in the evening when I'm home.

John, My Raspberry PI shipped today, so I hope to be trying this myself over the weekend. I am interested to hear if you resolve this issue, and if not I may be looking at it myself.

Yes, just received mine. Odd thing is its got a Samsung CPU. On 24/05/2012 15:10, Dave Walker wrote: John, My Raspberry PI shipped today, so I hope to be trying this myself over the weekend.

Re: [Ql-Users] Errors with uQLx on Raspberry Pi
Well if they are piggy backed that would explain it, rather unusual but a good idea. On 24/05/2012 16:25, Norman Dunbar wrote: On 24/05/12 15:38, Malcolm Lear wrote: Yes, just received mine.

Re: [Ql-Users] Errors with uQLx on Raspberry Pi
John, back at home, I can't seem to find the ARM sources right now, but from memory: I had to initialize the sigsegv signal handler differently (putting the handler into sac.sa_sigaction instead of sac.sa_handler (in unixstuff.c) in order to get a siginfo_t as second argument instead of a struct sigcontext to the SIGSEGV signal handler. In the signal handler, I could then get the fault address from the siginfo_t (the sigcontext doesn't seem to have it on ARM Linux). I think the correct member was siginfo_t-fault_address. What happens in your code seems to be that you're not getting the correct fault address, the code finds out this is not within the QL's address space and bails out. If I remember right, those were the only changes to make it work. (Not on a RPI, but on a Genesi ARM Smartbook, but that shouldn't matter) If you need more help, just come back on me.
