BF609 SWU doesn't work

Category: Software
Product Number: ADSP-BF609
Software Version: CCES

I am trying to set-up SWU0 (match block #0) to generate interrupt on write access within specified address space (in L3 cached memory).

I followed the programming sequence specified in ADSP-BF60X BLACKFIN PROCESSOR HARDWARE REFERENCE but memeory write access doesn't trigger any event. I checked in debugger wheter all registers are set-up correctly, but SWU is still not working

Maybe somebody knows how to solve the issue.

  • Hi,

    I am trying to use SWU in Watchpoint Mode, match on address within range, count disabled, interrupt enabled.

    Everything seems to be programmed correctly (registers content verified in debug mode), but memory access within defined range doesn't change status and doesn't invoke any interrupt.
