Segger Embedded Studio Pin Configuration Registers View

[Sebastian]

Hello All,

Is there an explanation why the Pin Configuration Registers are not available for viewing in the Registers view of Segger Embedded Studio?

If there is can someone explain how to show them or it is only possible via the memory view?

Thanks.

Hi  Vasileios, 

you should be able to see the GPIO pin configuration under the P0 group in the Registers window, i.e.

 

Best regards

Hi Bjorn,

Thanks for coming up:

I don't get the CONF registers. I only get up to DETECTMODE.

I am running Segger studio v3.40 (64-bit) on Windows 10 if this helps.

Which SDK version are you using? Could you check if the nrf52.svd file you're using has the following register section after the entry for the DETECTMODE register?

Hi bjorn,

I am using SDK 15.0.0.

Both nrf52.svd and nrf52840.svd that I am using do have the PIN_CNF definition in them.

Still registers do not appear.

Thanks for your help.

Could you try updating to SES v3.34 or 3.40( latest i think) and see if that resolves the issue?
