Hello,
This patch set adds support for the Nitrogen board by 96Boards.
The support consists of:
- adding configs for Cortex-M4, nRF52832 SoC and Nitrogen board,
- adding bbclass with pyocd-based do_flash_usb() implementation.
Tested on Nitrogen and on QEMU so I hope I didn't accidentally
break anything.
Verification:
1. Install pyocd.
2. Connect Nitrogen and make sure you can see Bus 001 Device 004: ID 0d28:0204 NXP ARM mbed
in lsusb.
3. Build a sample app:
$ MACHINE=96b_nitrogen DISTRO=zephyr bitbake zephyr-philosophers
4. Flash app to the board:
$ MACHINE=96b_nitrogen DISTRO=zephyr bitbake zephyr-philosophers -c flash_usb

HAL for Nordic chipsets is one of Zephyr subprojects. It is downloaded
by default by west. Clone the HAL repository so it can be used for
building images for boards with Nordic chips.

Add include for Cortex-M4 tunes and nRF52832. The nRF config
appends 'nordic' to MACHINEOVERRIDES, so the kernel recipe
can include Nordic HAL when this override is detected.

The board is based on Nordic nRF52832 Cortex-M4 chip.
The support depends on Nordic HAL. It has been verified
with zephyr-philosophers and zephyr-shell sample applications.

Depending on the target board and/or flashing method, it may be desirable
to have access to .bin or .hex files instead of .elf. Remove .elf extension
from ZEPHYR_MAKE_OUTPUT and let users of that variable specify the extension.
Append .elf to all identified users, since they worked with .elf so far.

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.

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

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 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

Flash boards supported via pyocd:

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.
