Sometimes the toolchain tries to put a relocation which is not suitable to access variables in a read-only section. The nds32 gcc uses GP-relative signed 17-bit relocation to access variables stored in .rodata (eg lwi.gp $r0, [ +gp ]) That's wrong since $gp is pointing in the middle of .data and .bss in the SRAM, while .rodata is sitting in flash. Since on IT8380, the flash is at 0x00000 and the SRAM is at 0x80000 (512kB further), the linker will fail trying to create the signed 17-bit relocation (it detect that it needs to truncate it) Force the compiler to put another relocation as a workaround for now.
