That worked perfectly! Thanks.

Hi Rod,
I am sorry for the confusion.
I was able to replicate the issue. There is an issue in the adc sample, but it is a quick fix.

Please change in main.c line 19 to:

CONFIG_BOARD_NRF9160_PCA10090NS

and in prj.conf file add:

CONFIG_MAIN_STACK_SIZE=4096

Then you should be able to run the sample.

Hi Martin, I am pretty sure I have this set up OK, I cant be sure as Im away on business away from my development machine at this minute but will check on my return. If not, I will reinstall

Regards,

Rod

Hi Rod,

Have you sourced the zephyr-env.sh in the https://github.com/NordicPlayground/fw-nrfconnect-zephyr repo, since it looks like compiler struggles with finding the definitions which are in https://github.com/NordicPlayground/fw-nrfconnect-zephyr/tree/master/ext/hal/nordic/nrfx/mdk file.

You should have this structure:

Hi Martin,

Sorry, Im missing something obvious here, so obvious I can't see it!

I have copied the source for the secure boot as above, and try to compile using..

cmake -GNinja -DBOARD=nrf9160_pca10090 ..

then, when I run ninja, I get...

I guess I'm pointing to an old .h file somewhere?

So, then I tried using your .hex file.I was able to program the board successfully with secure boot.

When I try to build the ads code, I get more errors

Again, looks like eIm pointing to an incorrect .h file?

I went through the errors and replaced the definitions .n the adc code, for example, replaced ADC_1ST_CHANNEL_INPUT with ADC_1ST_CHANNEL_ID. I can get the code to build but get the bus error again, but I guess Im just working round the main problem of my include files?

Sorry for being stupid here, Im a h/w guy trying to make it in a s/w world!

Martin Lesund — Mon, 25 Mar 2019 12:34:13 GMT

Hi Rod,

If you look in the commit for the secure_boot in that repo you can see that there has been added three lines.

	/* Configure SAADC as non-secure */
	secure_boot_config_peripheral(
		NRFX_PERIPHERAL_ID_GET(NRF_SAADC_S), 0);

If you add that and reflash you should be good.

Also adding the precompiled .hex if you have any issues: devzone.nordicsemi.com/.../secure_5F00_boot.hex

Use nrfjprog to flash the file, with the command: nrfjprog --program secure_boot.hex -f nrf91 --sectorerase -r --verify
