Hi, I have been trying to get interrupts working on my B32 board for a couple of days now and am really stuck. My problem is with the @interrupt qualifier. Whenever I use it I get a linking error "unexpected bank location" The manual clarifies this as, "an interrupt function or a function accessing the PPAGE register is located in a bank" ???? My link file is as follows; # Link command file for MC68HC12B32 +seg .text -b 0x8000 -n .code # program start address +seg .const -a .code # constants follow program +seg .data -b 0x800 -m 0x400 # data start address +seg .eeprom -b 0xd00 -m0x300 # eeprom start address if needed +def __sbss=@.bss # start address of bss /cosmic/cx12/lib/crtsi.h12 # startup file (or crts.h12) # enter object files here /cosmic/cx12/ujet/porta.o /cosmic/cx12/lib/libi.h12 # C library (if needed) /cosmic/cx12/lib/libm.h12 # machine library +seg .vector -b 0xffd0 # vectors start address /cosmic/cx12/ujet/vector.o # interrupt vectors +def __memory=@.bss # symbol used by library +def __stack=0xc00 # stack pointer initial value Would appreciate some help. What am I doing wrong??? |

I think I've solved this? If I use the -bs0 option my code will link OK. Can anybody confirm that I'm right? |

Hi, You simply need to link with option -bs0 to disable the linker banking mechanism which is not relevant for a B32.
