LEON3, RTEMS 5.1 and NASA cFS - EXE Crash

[KM-AL]

Hello,

I have been trying to get NASA's cFS to run on RTEMS on top of SPARC LEON3.

I use gaisler's RCC (RTEMS Cross Compiler) 1.3.1 and TSIM3. I can build and test RTEMS applications just fine.

This thread has been very helpful so far: #314

I created my own toolchain and generic RTEMS OSAL and PSP layers based of PC-RTEMS as discussed in that thread. I can successfully create an exe, however, my issues start when I try to run it. The program runs and exits when it shouldn't. It seems to crash early on in "_Workspace_Handler_initialization" due to an "_Internal_error".

Here's a screenshot of the simulator's output:

Unfortunately, I can't figure out why that happens exactly. I tried changing a lot of options and defines in both OSAL and PSP folders as well as the toolchain itself with no success, I always get the same error. I have a feeling it's not from the PSP or OSAL files but maybe the way the exe file is linked and generated.

Here is my toolchain file for reference:
toolchain-sparc-rtems5.cmake.txt

Could the params in RTEMS_BSP_C_FLAGS be relevant to the issue? I tested different combinations yet nothing seems to change.

I feel like it be a minor thing I need to change or I probably missed something big... In any case, any help or guidance will be appreciated!

I figured out the issue, I had to modify the define CONFIGURE_EXECUTIVE_RAM_SIZE found in the cFS/osal/src/bsp/generic-rtems/src/bsp_start.c file. Increasing it made the executable run properly. Keeping this thread in hopes it'll help somebody that might face the same issue in the future.
