[ECOS] Wrong asserts in mpc5xx var_intr.h?

Hi Andreas,

I wrote this code a long time ago, so I can't say for sure without doing some tests. At first sight, It seems you are right and the Asserts should be the other way around.

I ordered the vectors in such way that all VECTORS < CYGNUM_HAL_INTERRUPT_IMB3_QUADCA_CI1 are from devices that are connected directly to the SIU controller, so they can only have priorities from 0-7. All others >= CYGNUM_HAL_INTERRUPT_IMB3_QUADCA_CI1 come from sources that are connected to the IMB3 controller, so there priorities from 0-31 are valid.

Could you try and see if it solves you problem ?

Bob
