Hi Naveen,
I fixed the missing .hex issue and I'm ready to send v3.
I also experimented with your last suggestion, i.e. building test cases
with MACHINE=96b-nitrogen and I observed the following:
It is possible to build when I provide IMGDEPLOYDIR variable somewhere,
e.g. in 96b-nitrogen.conf. However, for other platforms, this variable is
provided only in classes/zephyr-qemuboot.bbclass. I've also tried to build
test cases for arduino-101-ble and it failed with the following reason:
Error, the PACKAGE_ARCHS variable (all any noarch
${PACKAGE_EXTRA_ARCHS_tune-armv6m} cortexm0-vfp arduino_101_ble) for
DEFAULTTUNE (cortexm0) does not contain TUNE_PKGARCH (cortexm0t2-vfp).
Additionally, when I provided IMGDEPLOYDIR in 96b-nitrogen.conf, I tried to
execute test cases with -c testimage. It failed on running qemu.
According to my observations, my understanding is that the test cases are
currently designed for being verified on qemu. Do you expect the
96b-nitrogen support to contain automatic test cases execution on the
hardware, or just the possibility of building? If it just the matter of
building the .elf files (you can flash them manually), then I can push v3
today.
Best regards,
Wojciech
