SPU NRF53 not run non secure app

[Roberto Cortez]

No available samples initiate the non-secure CPU (CONFIG_SPM = y)
the secure cpu is loop!

Zephyr master
NRF master

Help me please!

The test consists of running a simple hello world on cpuns nrf5340pdk.

Thank you.

That is strange. Eariler I told you to run rfjprog --eraseall first. Could you instead run nrfjprog -f NRF53 --eraseall, to specify that the flash in the application core should get erasesd.

Could you test this file?

merged.hex

Then run the following commands:

nrfjprog -f NRF53 --eraseall
nrfjprog -f NRF53 --program merged.hex

nrfjprog --pinreset

If that doesn't work, could you upload the file zephyr\samples\hello_world\build\zephyr\merged.hex, and I can test it on my board.

Best regards,

Simon

Hi Simon! tks for the answer!

FYI nrfjprog -f NRF53 --eraseall no effect, I have been using --recover to clear the flash and the UCR!

Your merged.hex doesn't work either!

I found a flaw in the jump to the correct block of the flash, to get around this in this case I am changing the file spm.c line 38 from:
((NON_SECURE_APP_ADDRESS) / (FLASH_SECURE_ATTRIBUTION_REGION_SIZE))
for:
((NON_SECURE_APP_ADDRESS) / (FLASH_SECURE_ATTRIBUTION_REGION_SIZE) -1)

but it gives me problems when I start MCUBOOT!

I need to implement FOTA and I need MCUBOOT to work!

another test I did was with the NCS V1.2.0 version, it seems to work, but the development of my sw depends on some features already implemented in the latest version!

This ticket was marked as "Verified" and it was removed from my queue, and that is the reson I haven't answered you. I will look into this.

[Simon]

What version of the nRF53 PDK do you have?
