In my project, I exclude the .cinit section from the linker's auto-generated .cmd file, using the .cfg. I then place the .cinit section using my own .cmd file. Up to this point, everything builds and links. Here is the .map file that gets generated:

Next, I try to create a symbol in my .cmd pointing to END of .cinit. This results in the error:
"../IcscTestApplication.cmd", line 65: error #10099-D: program will not fit into available memory. placement with alignment fails for section ".cinit" size 0x6afec . Available memory ranges:
L2SRAM size: 0xfffc0 unused: 0x47af7 max hole: 0x47aec
error #10010: errors encountered during linking; "Core0.out" not built
So basically this works:
SECTIONS // part of checksum
{
.cinit: load > L2SRAM, START(_CinitStart)//, END(_CinitEnd)
}
And this does not work:
SECTIONS // part of checksum
{
.cinit: load > L2SRAM, START(_CinitStart), END(_CinitEnd)
}
