Hi Björn
I have the same issue with the SES 4.42 with the nRF9160. Is there a fix available for this issue or is it still pending?

Thanks Adrian

Hi Bjorn,

I am having a similar problem using SEGGER Embedded Studio for ARM
Release 4.12 Build 2018112601.37855
Windows x64

When I select a Group under Registers, GPIO is not shown. So far, the only way I have found to display the GPIO configuration registers is by directly looking at their memory locations, which is not easy.

Is there a newer configuration file to support viewing the GPIO registers for the nRF52832? I am currently using the nRF52-DK, although we may move to the nRF52840 in the future.

Thanks for your help,

Scott

Hi Bjorn,

The GPIOTE registers are also not showing correctly. I've downloaded your ZIP file, but they are still not showing.

I've tested SDK 15.0 and 15.2 using SES V4.10a. I'm using nRF52840.svd.

I've checked the .svd file using Ozone debugger from Segger, and the GPIOTE registers show correctly.

Here are the registers shown in debug mode:

Faced a similar problem. They looked for differences between files and nrf52832.vvd and for nrf52840.dvd. Found the difference in the description of multichannel registers described like this:

<register>
          <dim>0x8</dim>
          <dimIncrement>0x4</dimIncrement>
        ...
</register>

if the description is changed to this (not to delete 0x, but to represent the numbers in decimal encoding.):

<register>
          <dim>8</dim>
          <dimIncrement>4</dimIncrement>
        ...
        </register>

then the registers are displayed correctly.

P.S. CMSIS wizard has a similar problem. It also does not correctly work out the values specified in the hexadecimal system.

P.P.S My file with changes: devzone.nordicsemi.com/.../nrf52840.rar

replace your file in directory: nRF5_SDK_15.2.0\modules\nrfx\mdk

Hello Hurley,

Just use the file attached to bjorn-spockeli's message above. This solves the issue.

HurleyResearch — Tue, 13 Nov 2018 21:01:26 GMT

confirmed that with latest SES (4.10a), and tried both nrf52840.svd files, and still cannot see psereset reg in uicr.

Perhaps a similar issue, I cannot see several of the regs in NRF_UICR in SES, for instance PSELRESET is missing. I am using SES 3.34 and SDK 15.2. I will try to update SES. Same issue with nrf52840.svd that ships with 15.2, and the above posed svd file. Any help appreciated... I've got an issue with not being able to set the reset pin selection! Thanks!

Hi Bjorn,

I confirm that this solves the issue. I can now see all the GPIO registers even after DETECTMODE.

Thank you very much.

I will close the question.

It should be visible now, I had to zip it in order to get the upload to finish properly.

Hi Bjorn,

Thanks for coming back. I cannot see yout attachement.

RE: Segger Embedded Studio Pin Configuration Registers View

bjorn-spockeli — Tue, 26 Jun 2018 08:40:30 GMT

Sebastian : I sincerely apologize for the very late reply.

I did some changes to the nRF52840.svd file and I am now able to see the Pin Configuration registers during debugging. Could you try to use the attached .svd file and see if that resolves the issue?

Thanks bjorn. Let me know when you have something.

RE: Segger Embedded Studio Pin Configuration Registers View

bjorn-spockeli — Thu, 07 Jun 2018 14:06:38 GMT

Ah, I was using the nRF52832 DK when testing this. I am seeing the same issue as you when I am using the nRF52840 DK and the nrf52840.svd register definition file when debugging in SES. I am not seeing the same issue when using Keil, so there has to be something with how SES is interpreting the .svd file. I will investigate this internally.

One above is usbd_cdc_acm but I saw the problem even in blinky.

Thanks.

bjorn-spockeli — Thu, 07 Jun 2018 13:23:40 GMT

Hmm, then I do not know why the Pin Configuration registers are not shown? Which example from the SDK are you using?

RE: Segger Embedded Studio Pin Configuration Registers View

Sebastian — Thu, 07 Jun 2018 08:54:56 GMT

I am running SES 3.40 64 bit.

RE: Segger Embedded Studio Pin Configuration Registers View

bjorn-spockeli — Thu, 07 Jun 2018 08:41:02 GMT

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

RE: Segger Embedded Studio Pin Configuration Registers View

Sebastian — Thu, 07 Jun 2018 07:53:00 GMT

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.

RE: Segger Embedded Studio Pin Configuration Registers View

bjorn-spockeli — Thu, 07 Jun 2018 06:37:28 GMT

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,

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.

RE: Segger Embedded Studio Pin Configuration Registers View

bjorn-spockeli — Wed, 06 Jun 2018 14:14:23 GMT

Hi Vasileios,

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

Best regards

Bjørn
