Hi Naveen,
I investigated the arduino-101-ble problem and for me it's non trivial to fix.
It's not related to the same missing variable that I spotted in the Nitrogen
case, but rather there are some inconsistencies with architecture-related
variables i.e. PACKAGE_ARCHS and TUNE_xxx. I did not find any way to fix it.
For now I pushed v3 with Nitrogen support. If I find a way to straighten out
the Arduino case, I'll push a separate patch set for that.
BTW, I also have 96boards Avenger96 support patch set ready. It depends on one
commit from the Nitrogen patch set (Cortex-M4 tune), so I'll send it out right
after Nitrogen support is merged.
Regards,
Wojciech

Hi Wojciech,
Yes, testcases are currently being verified only on qemu, so if we can just
build testcases for now that should be sufficient. If you are able to flash and
execute tests manually on HW, that would work. Please send v3.
Can you fix for arduino-101-ble as well ?

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

Subject: [yocto] [meta-zephyr][PATCH 5/5] zephyr-flash-pyocd.bbclass: support
for flashing via pyocd
Flash boards supported via pyocd:
MACHINE=xxx bitbake yyy -c flash_usb
The only supported board for now is 96Boards Nitrogen. Modify its config
accordingly.
Modify helloworld and philosopers samples with adidtional .hex output file
deployment, as this format is required by pyocd.
Describe the feature in README.
