Today i got the RTEMS ticker sample executable working as expected for the
first time. I'll clean up the code a bit and commit it to my public git repo
next week i hope.
whats working:
+ translation lm32 asm -> tcg
+ interrupts (well, in some way ;)
+ basic lm32 timer and uart
+ basic lm32-evr board support
Todo:
+ optimized translation (?)
+ proper debug/hw exception handling
(someone should check the interrupt processing)
+ single stepping
+ lm32_dis.c / print_insn_lm32()
btw. nice lecture at 26c3 :)
