How to view FPU registers in Debug mode?

kavehfirouzi — Tue, 05 May 2015 21:53:52 GMT

I am working with a M4f processor and I need to look at FPU registers while I am debugging. The description for the General Registers says general purpose and fpu register group but I can only see the general purpose registers. What should I do?

Regards,

Hi Kaveh,

Do you sue KDS ?

If yes , it only shows the core registers on KDS 2.0 and also the before KDS version , and you can refer to here to add register detail view.

Hope it helps

Hi,

I am using KDS 2.0. It doesn't show me FPU registers. I have also already installed EmbSysRegView, it also doesn't include FPU registers.

Hi K,

The EmbSysRegView only shows what is present in the CMSIS-SVD files. Usually, the CMSIS-SVD files (according to ARM Inc.) do not include the core registers. However, the new Kinetis Design Studio v3.0.0 (see New Kinetis Design Studio V3.0.0 available ) comes with extended CMSIS-SVD files which now include core registers:

(you might use these SVD files from v3.0.0 in your v2.0.0 too).

As you can see from above, it shows now the system control, NVIC, Systick.

I notice that things like FPCCR, FPCAR, FPDSCR are somehow missing (I have filed a ticket about this).

I hope this helps,

Erich

Bump - has there been any action on this? The embsysregview extension is missing views for many registers on the K22F: UART4, UART5, etc.
