BF609 SWU doesn't work

Hi,

To assist you better, please let us know which mode you are trying. Watchpoint Mode or Bandwidth Mode?

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.

Regards

Michał

Hi Michał,

Please find the attached example to configure SWU to monitor access to an external memory region.

Hi Divya,

Thank you for solving my issue. It works but only on SWU6 as in your example.

Have you checked your code on SWU0 or SWU1? In my opinion it still not working on SWU other than SWU6.

Michał

Hi Michał,

Could you please confirm the below points are taken care:
1. Modify the Lower and Upper Address Register in SWU0 and SWU1.
2. Change the interrupt iid in the adi_int_InstallHandler API.

Hi Divya,

I confirm that I modified Lower and Upper Address Registers in SWU0 and SWU1 and I changed interrupt iid

Hi Michal,

 To assist you better on this, could you please share your project to simulate the issue.

Hi Divya,

As the whole project is very big, I extracted only relevant procedure (see attached file).

Changing the SWU_IDX value you can select SWU unit number. In my project it works only for SWU6, but for other SWU units it doesn't work.

Hi Michal,

Please find the attached code which uses SWU5 on ADSP-BF609 EZ-kit. It's working fine for us and you can use this as a reference to develop your application.3666.SWU.zip

Please refer the above tabular column. Each SWU is dedicated to the specific peripheral for transaction monitoring.

Hi Divya,

Now everything is absolutely clear for me.

The key information is that "Each SWU is dedicated to the specific peripheral for transaction monitoring".

I haven't found such a information (including the above table) in any document provided by AD.

Hi Divya,

I have implemented SWU services for different peripherals. Generally it works, but I cannot succeed with L1 memory watchpoints. According to the SWU assignment given in your previous message, the SWU3 should be dedicated for L1 memory associated with Core0. Unfortunately, it doesn't work. Could you check whether it works or not.

Michał
