TAMPC on the nRF54L15-DK

Sorry for the late reply.

Currently, using DTS or Kconfig in this way is not supported for TAMPC, so it must be done through direct register writes and by working with the MDK.

We found an issue where Channel 3 is not resolved correctly in nrf_tampc.h. Specifically, NRF_TAMPC_ACTIVESHIELD_CHANNEL_COUNT is not being resolved as expected. This is caused by incorrect symbols being used in the following conditional statements:

Following symbols defined by MDK in nrf54l15_types.h should be used instead:

TAMPC_ACTIVESHIELD_CHEN_CH3_Msk
TAMPC_ACTIVESHIELD_CHEN_CH2_Msk
TAMPC_ACTIVESHIELD_CHEN_CH1_Msk

As a temporary software workaround, you can either:

Manually correct the definition in nrf_tampc.h, or
Avoid using the nrf_tampc_activeshield_mask_t enumerators and instead use the MDK symbols directly (e.g., TAMPC_ACTIVESHIELD_CHEN_CHxxx_Msk).

What is the error log? Could you provide it?

After that update completed, I get build errors if either one of these symbols are in the prj.conf file:

CONFIG_TAMPC=y
CONFIG_NRFX_TAMPC=y

Try this way:
In the Welcome View: the Run west update action under Manage SDKs > Manage West Workspace.

Please ensure to use the nRF Connect SDK Command Prompt and run "python -m west update".

Could you run "west update" under C:\NCS\v3.2.1? Let me know wether it can help or not.

Hi Amanda. I'm building using the nRF extensions in VS Code. NCS version 3.2.1.
Build log attached.

Hi,

What NCS version are you using?

[quote user=""] I can compile this code for channel 0, but if I change the reference to channel 3 it doesn't compile.[/quote]

How does it not compile? Could you elaborate further or provide the log?

Regards,
