Bare metal application for nRF53

[Semiory]

Hi,

could some one inform me how to create a bare metal project for nRF5340 (Network Core/Application Code)?
The specification gives everything to create an own stack on the chip.

It was simple to create a bare meal App for nRF52, but for nRF53 there is any driver lib given.

The examples given in a Tutorials (nRF Connect SDK Tutorial - Part 0-1-2 | NCS v1.4.0) are extremely restricted.

There is no sufficient tutorial with the description how to create a project from scratch with or without OS (Zephyr). Better without OS...

Simple Projects created directly in SES are not working at all.

Best regards

Hi, 

First I think there is no option to go "bare-metal" or without RTOS. nRF53 supports only zephyr based projects from Nordic as far as I know. 
I would suggest moving to NCS1.5.0 and going through samples in NCS and zephyr and try them out on nRF53.
Also instead of using SES, I would recommend going with the CLI interface and using the zephyr tool west for building and flashing since it is more convenient with this dual code chip.

Best of luck!

Vojislav.

Is the recommendation against using SES for the nrf53 still true?  

And is there any plan to resolve this?

[Vojislav]

Frankly, I have not used SES for nRF53. I use west CLI in combination with VSCode. Regarding this, I recommend moving to the latest on the NCS since there were some flashing issues when rebuilding the project, but that is now resolved. 

For SES support I would open a new ticket to get a clear answer from nordic. 

Best regards,
Vojislav.

Vojislav Do you have any tips on VSCode setup for the 5340?  I currently use the cli and make/flash from the vsc terminal and have no debugging support.  Pretty new to Zephyr and west so I have avoided both for the moment ... yet another build system always makes me cringe.

there are several plugins for vs code that works with zephyr. Otherwise, you can add tasks to vs code to execute things you would otherwise do by hand in the terminal.

I know that zephyr contributors are working on providing more helpful vs code tutorials, but until that comes you can use these:
