Problem. Booting RTEMS exmaple application Hello World with MVME2304-0141 CPU

[Ziaulhaque Qazi]

Hi All

 

While trying to boot MVME2304-0141 CPU with RTEMS-10.2, first it was noticed that the RTEMS was not recognizing the CPU board. Getting into detail, it was found that the processor PPC-604e was not listed in the Motorola.c file. I changed just one line for mvme-23xx boards to indicate this processor rather than simple PPC-604 which was listed there originally.

 

The earlier message of "Unknown Board" was no more there. However the boot was still not successful wit following response noticed before system halted.

 

RTEMS 4.x/PPC load:
Uncompressing the kernel...
done
Now booting...

Welcome to rtems-4.10.2(PowerPC/Generic (classic FPU)/mvme2304) on MVME 2300
-----------------------------------------
idreg 0 = 0x48011057
OpenPIC found at C1000000.
pci : Configuring interrupt routing for 'MVME 2300'
pci : No bridge from bus 0 towards root found
pci : Unable to match device 0:0x0B:1 with an int routing table entry
pci : No bridge from bus 0 towards root found
pci : No bridge from bus 0 towards root found
Cleared PCI errors: pci_stat was 0x2280

 

I need the guidance that which of the files may be modified (and how) to overcome the differences.

 

Best Regards
