Dear RTEMS Users and Developers, I have built RTEMS 5 with EPICS 7 and tried to boot my application on mcp750 cPCI board. The first thing that I have encountered is that the boot file is in the elf format so I have converted it to the binary one.: powerpc-rtems5-objcopy -I elf32-powerpc -O binary myApp.boot myApp.boot.bin So far so good Next, I booted the system with my app and it fails in the *bsp_early* function in bsps/powerpc/motorola_powerpc/start/bspstart.c
The boot sequence: Network Boot File load in progress... To abort hit <BREAK> Bytes Received =&1270208, Bytes Loaded =&1270208 Bytes/Second =&635104, Elapsed Time =2 Second(s) Residual-Data Located at: $01F88000 Model: (e2) Serial: MOT0000000 Processor/Bus frequencies (Hz): 366680480/66671508 Time Base Divisor: 4000 Memory Size: 2000000 Residual: 1f88000 (length 27148) PCI: Probing PCI hardware RTEMS 5.0.0/PPC load: Uncompressing the kernel... done Now booting... ----------------------------------------- Welcome to rtems-5.0.0 (PowerPC/Generic (classic FPU)/mcp750) on Mesquite cPCI (MCP750) ----------------------------------------- idreg 0 = 0x1208029271 OpenPIC found at 0xc1000000. pci : Configuring interrupt routing for 'Mesquite cPCI (MCP750)' pci : No bridge from bus 0 towards root found pci : No bridge from bus 0 towards root found pci : Device 1:0x0b:0 routed to interrupt_line 27 pci : Device 1:0x0d:0 routed to interrupt_line 25 Cleared PCI errors: pci_stat was 0x2280 OpenPIC Version ?

The mcp750 has 32MB of RAM. How to detect what is the real cause of INTERNAL_ERROR_TOO_LITTLE_WORKSPACE ? Would it be the problem with the linker script ppcboot.lds?
