Hi, I am a new user of RTEMS and I have a weird issue using it with Qemu. I am using RTEMS release 4.11.3. I am using Qemu v 2.5.0 I am running in a Linux Ubuntu VM (64 bits)
I can successfully launch various applications (.ralf) with qemu-system-ppc, like so for example: qemu-system-ppc -M prep -kernel ./hello.ralf -bios /home/qemu_fakerom/qemu_fakerom.bin -cpu 750cxe -nographic -no-reboot but if I specify an amount of available memory larger than 256Mb to Qemu (with the -m option) then the RTEMS kernel will not boot and I will have the following output (stuck at 'Now booting'): Model: Serial: Processor/Bus frequencies (Hz): 300000000/100000000 Time Base Divisor: 1000 Memory Size: 18000000 Residual: 102afd4 (length 27148) PCI: Probing PCI hardware RTEMS 4.x/PPC load: Uncompressing the kernel... Kernel at 0x00000000, size=0x495b0 Initrd at 0x00000000, size=0x0 Residual data at 0x0004a000 Command line at 0x00051000 done Now booting... I am wondering if I am hitting some sort of limit with the PowerPc PREP or is this an issue with the bootloader provided with RTEMS. Anyone ever has this kind of behavior? Any help will be greatly appreciated, Eric
