Hi Maurizio,

Can you test with this fix: spm: kconfig: use SYSTICK as system clock driver instead of RTC1 by hakonfam · Pull Request #6359 · nrfconnect/sdk-nrf (github.com)?

NCS1.8.0 is close to release, you may see this fix released with a later version of NCS, anyway you can use this directly to your current NCS now.

Best regards,

Charlie

Hi Maurizio,

Our development team has decided to fix this bug in the next sprint and it is going to be fixed in a few weeks. I will keep you updated on this page.

Best regards,

Hi Maurizio,

Based on the current roadmap, I do not suggest you continue using SPM with this issue since you can hardly get further support on your development. It would be quite a risk to develop a new product base on a component that is going to be deprecated.

Instead, I can help you if you have any concerns about TF-M. TF-M only requires a dedicated UART port for debugging purposes and it is disabled by default.

Best regards,

Charlie

Hi Charlie,

I am very sad that there is no solution to correct the problem using SPM. The solution you propose to use TF-M has negative implications for my project. In my project only one UART is available and TF-M requires a dedicated uart, besides there are many other differences.

Don't have any suggestions for using SMP with serial speeds other than 115200?
Please help me.

Maurizio

Hi Marurizio,

Sorry for the late follow-up. It is a bit hard to find proper help for the current SPM because we have decided to deprecate SPM shortly. It will be replaced by TF-M so I think this should be resolved using TF-M as the secure component instead of SPM. You can find more useful information about TF-M from the following pages:

Running applications with Trusted Firmware-M

Trusted Firmware-M Documentation

Hi Marurizio,

Thanks for the feedback. I can repeat this issue. Need a bit more time to investigate the cause.

Best regards,

Charlie
