I’m fixing mc1322x/redbee-econotag port. (vtimers, hwtimers make RIOT crash)
I was suspecting the ISR not beeing executed, as timer’s callbacks never happened.
I found that piece of code that may be wrong (cpu/arm7_common/common.s)
.if (CPU != mc1322x) /* jump into vic interrupt / mov r0, #0xffffff00 / lpc23xx */ ldr r0, [r0] add lr,pc,#4 .else
/* mc1322x seems to lack a VIC, distinction of IRQ has to be done in SW / ldr r0, =isr / mc1322x */ .endif
I’m not really skilled in ARM assembly files, but I think CPU is not a defined variable/macro in .s files.
So, the mc1322x hack is never compiled, and that makes RIOT crash each time we use interrupts. .
How would you correct that ? I read somewhere we could use GCC instead of AS to use macros and pre-processing.
Thx for your help
