Newer SDK samples do not compile/run on old 9160DK hardware (without onboard flash)

[Thanos]

Hi,

What is the correct way to build an application (say asset_tracker_v2) included in a newer SDK (2.6.1 for example), using a nRF9160 DK without on-board SPI flash device?

I have an old 0.9.0 DK and several compilation and run-time errors pop-up now that I switched to 2.6.1 SDK while trying to compile a multi-image application. Disabling mx25r64 in several 0.14.0 overlay files did not fix the problem. Specifing board revision number in VCS extension did not solve the problem either.

Any clean solution?

Thank you!

External flash is required for Asset Tracker V2.

Also, Board Controller Firmware version must be >=v2.0.1 to enable pin routing to the external flash.

Moreover, only Modem Firmware version 1.3.6 is compatible with NCS 2.6.1: Modem firmware (nordicsemi.com)

So those who have an older 9160DK that does not have an external flash mounted, cannot test Asset Tracker v2 any more?  

It used to run fine on my 0.9.0 DK until recently..

which SDK version you were using?

ATV2 NCS SDK V2.6.1 clearly mentions external flash as a requirement

Hi,

It turns-out that all you need to do is to specify the correct board revision number (i.e. "0.9.0") in VCS. Then all samples run smoothly, even Asset Tracker v2, as tested in SDK 2.6.1.  The trick was to delete all previous builds/trials, deselect any 0_14_0 .conf files from the build, and start from scratch, after setting the correct revision number.

Thank you
