RE: nRF5340: BLE in PSA template

Dear Vidar,

Thanks for your response.

Found this ticket and it seems my plan of extending TF-M: PSA template with BLE and the further libraries needed in the project will result in a too big firmware size.

Will therefore have to rethink that approach.

Kind regards,

Patrick

Hi,

TF-M is included automatically if you select 'nrf5340dk_nrf5340_cpuapp_ns' as your build target, see Running applications with Trusted Firmware-M for details.

My guess is, that it is coming from the NET Core, as there is not enough space for the entire PSA code as well as the hci_rpmsg.

Now the question, where can I control, that for now only the hci_rpmsg goes on the NET core and then step by step include the further PSA components such as the b0n and the MCUboot?

The hci_rpmsg image will always go on the netcore if you build the LBS sample whileTF-M image will be on the app core.

Note that you can generate a memory report to see what the flash layout looks like for each core:

Kind regards,
