problem while trying converting c program from rtems4 to rtems5

[Rotem Dror MTH]

Hello,

We have an old program (written in c language) running on RTEM 4.10
we are trying to run this program with new environment - RTEM5 with gcc v10.2.0.
we also updated the linkcmds file according to linkcmds.base

we have done compellation and loading grmon3 successfully.

When we start to debug/run the program we get an error in file malloc_initialize.c, line 79: "INTERNAL ERROR NO MEMORY FOR HEAP"
We understand (from guide file named: c-user.pdf) that the problem should be because of configuration error.
Please let us know, where (or how) can we update this configuration? Or maybe this problem caused by a different cause?

If we proceed and skip this error, we stopped on bus error according to file userextiterate.c line 192: iter.previous  pointed to 0x0 address.

Best Regards
Rotem
