- christina_b 10y agoYeah, I saw, I haven't looked at it in detail but I think yours probably works better than mine since you did comprehensive testing. My only tests involved compiling my own firmware code, but from what I can tell, it works well, I haven't ran into any bugs yet aside from what I outlined in the README. The assembler/linker I'm using is not ideal, I want to get MC code emission working eventually. I saw that you mentioned limitations on ld/st, why not use lea for data? For example: BB1_12: # %sdram_clkman_update_end.exit2 mov r0, 2114982312 # long ld r2, (r0) lea r0, .str8(pc) # PCrel load lea r1, __FUNCTION__.sdram_init_late(pc) # PCrel load bl xprintf
- puppeh 10y agoNo reason I guess, except it means an extra instruction. I thought about adding a flag for "large model" compilation, but it's not been a priority so far.
