Yes, GCC/GAS generate 0xeafffffe (b 0x9098).
Can you tell me why? Can I left .word? Why is the jump offset 0x9098 ?
I figured out that 0xeafffffe is a loop (b -4)
ldr pc, pc, #-4
but I don't know why toolchain generate b -4 instead of b 0x1000 and I don't know how to fix it (without .word).
I don't follow, sorry. How did you even get to 0xeafffffe ?
My point is that GCC/GAS generate 0xeafffffe instead of 0xea0003fe when I use 'b 0x1000'.
How did you get to 0x1000 ?
That's why I use directive .word 0xea0003fe
Check some arm instruction quick ref for what 0xea0003fe really is and if it really is necessary or anything else work just fine as well.
instead of asm instruction 'b 0x1000'. But I don't know that: Can I leave that .word directive or I can not.
Another question: I asked in cover letter question about tools. Can I add them in h2200 directory or should I put them somwhere else?
I didn't receive the cover letter.
