I found time to evaluate migration from ADSP2148x to ADSP2156x.
CrossCore Embedded Studio is 2.9.3.
I think I found error in line 150 of int_dispatcher_215XX.asm
register R8 didn't be initialization.
Line 150 of int_dispatcher_215XX.asm is impossible because always NUM_MAPPED_HANDLERS > 0
fixing line number
