Hi,

I'm trying to compile the u-boot for arm-1026 architecture after adding the support for a new board. I'm facing the issue in accessing the global data "gd" (which is declared in "include/asm-arm/global_data.h" as #define DECLARE_GLOBAL_DATA_PTR register volatile gd_t *gd __asm__ ("r8") ).

As per the declaration "gd" is assigned the register "r8", however in the generated code this never happens, mostly it is the r6 register that is used for it. I checked that the -ffixed-r8 is getting used as a compile option. Can somebody point what might be going wrong?

Thanks, Pawan

Just to make sure: did you check for -ffixed-r8 in (some of) the makefiles or by looking at the actual compile command lines applied?

Amicalement,
