[elxr] (error #465) read-only small data overflow: 0xfa7960 (signed) didn't fit in 23 bits while performing relocation type R_V800_ROSDA23 (37) at address 0x100053a

Question

The ApplRomC2 is code flash extended user, I would like to allocate the object file (.rosdata) 
 Now, I am using for both code flash to store (.rosdata) 
 I am using GHS compiler and facing the above attached linker error. 
 Please suggest me what might be the issue.

JimB · Answer

The address where the section is being placed (e.g. 0x10005xx) is 25-bits, which is incompatible with the 23-bit restriction imposed on the data in the section. 
 You will need to understand the addressing modes of the device, and how the tools use them. There is lots of info about section placement and addressing mode in the "build_v800.pdf" compiler manual.

It appears that you are using the F1KM-S1 device. Looking at the GHS device file package, the linker file provides sections already for the extended user arear: 
 
 Unfortunately I do not have a GHS license so I cannot test my suggestion, but I believe the easiest way to accomplish what you are wanting is to change the default behavior of the compiler to put constants into the ".bconst" section using the "-section .rodata=.bconst" option:

If you are still not able to relocate the constants to the extended user area, I might suggest that you contact GHS support for help in doing this.
