Revision as of 15:33, 4 October 2018

Use cases

  • Linux kernel update when adding/developing a driver
  • When an application needs to be included into the firmware image archive
  • Update Elphel's PHP extension
  • C/C++ applications if developed on PC require a cross-compiler and require Yocto installation or some other alternative.

Other projects that use Python, PHP, Javascript, HTML, C/C++ on hardware (compiler is included in the firmware image) do not require this SDK use but it makes the process more convenient, e.g. by copying the built packages straight to the target hardware.

Description

  • Building embedded Linux image for Zynq ARMv7 platform - Elphel 10393 board
  • Yocto Poky revision = 2.0 (Jethro), recently updated to 2.4 (Rocko)

Features

  • Once everything is built it supports updating software projects (files and binaries) on the target system
    • access is set up in yocto's local.conf (see setup.py output) + ssh-copy-id
    • bitbake some-app -c target_scp from the command line or Eclipse IDE - see examples in elphel-apps-... at Git

Supported OSes

  • Kubuntu 14.04.3 LTS x64 (until June 2016)
  • Kubuntu 16.04 x64 (as of June 2016)

Required packages

Other dependencies

sudo apt-get install python-numpy

Output files

The names are listed as they appear in the u-boot configuration header file - actual output files have different names:

File(s) Description
boot.bin u-boot as the first stage bootloader = Secondary Program Loader (SPL) that boots u-boot-dtb.img
u-boot-dtb.img full size u-boot with a stripped device tree (cat u-boot.img some_stripped_devicetree.dtb > u-boot-dtb.img)
devicetree.dtb device tree with listed interfaces, zynq registers, interrupts and drivers
  • elphel393/bootable-images/mmc/devicetree.dtb - mount rootfs from mmc partition
  • elphel393/bootable-images/nand/devicetree.dtb - mount rootfs from NAND flash
uImage kernel, drivers
rootfs.ubifs, rootfs.ubi, rootfs.tar.gz rootfs in different formats - *.ubi* for NAND, *.tar.gz for mmc

The file are located at elphel393/bootable-images/, which is a link to poky's deploy directory elphel393/poky/build/tmp/deploy/images/elphel393/

  • complete set of files for rootfs in NAND Flash: elphel393/bootable-images/nand/
  • complete set of files for rootfs on MMC (micro SD card): elphel393/bootable-images/mmc/

Write files to media and boot

Boot from micro SD card

  • Use recovery or regular μSD card
  • EXT4 partition mounted as /

Detailed instructions

Boot from NAND flash

  • The default boot option - power on.
  • A UBIFS image is written to /dev/mtd4 - is mounted as /

Detailed instructions

Notes

Setup

  • Poky 2.4 Rocko

git clone -b rocko https://git.elphel.com/Elphel/elphel393.git
cd elphel393
./setup.py
cd poky
. ./oe-init-build-env
bitbake u-boot device-tree linux-xlnx core-image-elphel393

  • Poky 2.0 Jethro

git clone -b jethro https://git.elphel.com/Elphel/elphel393.git # or git clone git@git.elphel.com:Elphel/elphel393.git # if ssh public key is uploaded
# then follow the same steps as for Rocko

Notes:

  • The last line builds all targets.
  • If python-numpy was not installed

x393.h will not be generated > bitbake linux-xnlx will fail.
To recover:
1. sudo apt install python-numpy
2. run bitbake linux-xlnx -c link -f

  • if rerun setup.py updates all repositories and reruns other procedures.

$ ./setup.py
if you notice the kernel got updated then you might need to restart with bitbake linux-xlnx -c link -f

Compare built vs deployed software versions

cd elphel393
./check_versions.py root@192.168.0.9

Notes:

  • deployed = running on the target system
check_versions.py output in terminal

Build

All targets

bitbake u-boot device-tree linux-xlnx core-image-elphel393

Bootloader

bitbake u-boot

Output

  • boot.bin
  • u-boot-dtb.img

Notes

  • Since Poky 1.5.1: switched from u-boot-xlnx to u-boot - some of the u-boot-xlnx reached the upstream
  • Since Poky 1.5.1: u-boot introduced Kconfig and currently (as of 2016/01/22) is still migrating from autoconf - keeping both build methods working together.
  • Current u-boot uses the board's device tree blob to make a stripped version for itself - uncompiled device tree files are present in the u-boot sources

Device tree

bitbake device-tree

Output

  • devicetree.dtb

Kernel

bitbake linux-xlnx

Output

  • uImage

Notes

  • yocto jethro: Kernel version is 4.0, linux-xlnx
  • yocto rocko: Kernel version is 4.9.0, linux-xlnx
  • Device Tree Blob is compiled separately in linux-xlnx
  • Uncompiled device tree files are present in the linux sources provided by linux-xlnx

Rootfs

bitbake core-image-elphel393

Output

  • rootfs.tar.gz
  • rootfs.ubi,rootfs.ubifs

Details for development

Development for 10393

Notes

  • [FIXED] lighttpd-1.4.39, mod-cgi

compile warning:

implicit declaration of function 'chunkqueue_written'

results in lighttpd failing to start if mod-cgi is enabled:

lighttpd.

Note: why 1.4.36?!!

solution: exclude the 0001-mod_cgi-buffers-data-without-bound.patch from the file list that comes with the poky/meta/recipes-extended/lighttpd_1.4.39.bb

  • Invalidate chache/checksum on package code changes
    • SRCREV = "${AUTOREV}" - updates the checksum but the cache is not cleared/invalidated?

SRCREV <- AUTOREV <- AUTOREV <- "${@bb.fetch2.get_autorev(d)}" (bitbake/lib/bb/__init__.py)

def get_autorev(d):
   #  only not cache src rev in autorev case
   if d.getVar('BB_SRCREV_POLICY', True) != "cache":
       d.setVar('__BB_DONT_CACHE', '1')
   return "AUTOINC"

BB_DONT_CACHE ?!!!!!!!

Force to always execute recipe starting from a certain task:

recipe-outside-of-task: do_compile[nostamp]="1"
or
recipe-class-inside-task: d.setVarFlag('do_compile', 'nostamp', '1')

  • clone git repo over https in a recipe

SRC_URI = "git://git.elphel.com/project.git;protocol=https;branch=master"

Errors

  • Aborted, core dumped
    • Got when tried to build gstreamer1.0-plugins-base - error in one of the packages it depends on.
    • Possible reason - Kubuntu 14.04 - the system libraries are too old? The up-to-date Kubuntu release is 16.04.
    • Command (example):

bitbake libxau-native

    • log:
