Gary,

When I compile the following is output:

For the code in var_mk_defs.c:
HAL_UCACHE_SIZE = 0, HAL_UCACHE_WAYS = 0, HAL_UCACHE_LINE_SIZE = 0, CYGNUM_HAL_ISR_MAX = 62 and so on.

As for my port, the processor it is for has a much larger vector table. The SH2 7044 variant I based this on has exception vectors for the custom interrupt layout going up to 93 in var_intr.h whereas the SH2 7145 hash exception vectors going up to 129. Could the size of the vector table be causing a problem.

The 7145 also has no cache so I have used another cache definition file mod_regs_cac_3.h which specifies cache sizes as 0 and all addresses. Could this also be contributing. I am pretty new to eCos and there is some funky stuff which I don't as yet understand. It has been quite hard work performing a variant and platform port for board.

   Any help greatfully received. Many thanks.
