Description

Build the firmware for Elphel 10393 series camera systems from scratch.

Prebuilt releases can be found here.

Use cases

Update Linux Kernel when developing a driver
Include application to the default firmware package
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 written in Python, PHP, Javascript, HTML, C/C++ (gcc is installed on the system board) can be developed on the camera. Installing the framework is not required but it can simplify the development process.

Description

Building embedded Linux image for Zynq ARMv7 platform - Elphel 10393 board
Yocto Poky revision = 2.7.1 (Warrior) - builds in Kubuntu 20.04. Older OSes are not supported. Roll back to get built in 16.04.
~~Yocto Poky revision = 2.4 (Rocko) - builds in Kubuntu 16.04. Won't build in 18.04 or 20.04.~~
~~Yocto Poky revision = 2.0 (Jethro)~~

Features

Environment is set up with a single script
All Elphel projects are configured for Eclipse IDE:
- fpga projects (verilog)
- kernel
- applications projects
All steps for fpga projects are run from Eclipse IDE
- Read about setting up Eclipse based FPGA development
- VDT Plugin repository

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

Requirements

Kubuntu 20.04 x64
~~Kubuntu 18.04 x64 (as of Dec 2018) - Poky: 2.7.1 Warrior (not tested but might build w/o problems)~~
~~Kubuntu 16.04 x64 (as of Dec 2018) - Poky: 2.4 Rocko, 2.7.1 Warrior~~

Output files

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

File(s)	Build Command	Description
boot.bin	bitbake u-boot	u-boot as the first stage bootloader = Secondary Program Loader (SPL) that boots u-boot-dtb.img
u-boot-dtb.img	bitbake u-boot	full size u-boot with a stripped device tree (cat u-boot.img some_stripped_devicetree.dtb > u-boot-dtb.img)
devicetree.dtb	bitbake device-tree	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	bitbake linux-xlnx	kernel, drivers
rootfs.ubifs, rootfs.ubi, rootfs.tar.gz	bitbake core-image-elphel393	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

Read more about boot options.

Setup

Before building

Installing some dependencies:

sudo apt install git build-essential chrpath diffstat gawk texinfo zlib1g-dev python3-numpy libssl-dev

Installing old python2.7 (bitbake snapshot that we used has problem with python3.8):

sudo apt install python2.7
sudo ln -s python2.7 python2
sudo ln -s python2.7 python

Poky 2.7.1 Warrior (Kubuntu 20.04)

git clone -b warrior https://git.elphel.com/Elphel/elphel393.git

If you are a developer and plan to commit changes you should use ssh access instead: git clone -b warrior git@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 2.4 Rocko (Kubuntu 16.04)~~

~~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~~

Notes (required actions are already listed above): When trying to run bitbake on a new install got problems with older bitbake version (current build uses specific snapshot) and python3.8. So I install old python2.7 and linked it:

sudo apt install python2.7 python-numpy
sudo ln -s python2.7 python2
sudo ln -s python2.7 python

After this bitbake just complained about missing tools (git, build-essential were already installed):

sudo apt install chrpath diffstat gawk makeinfo

Program test_mcntrl.py that builds x393.h header files from FPGA code that runs during ./setup.py requires numpy and results in error output if missing Still setup.py continues, you need to look through its output few lines after

* x393
git host: git.elphel.com
Clone and checkout: x393

You may install numpy with

sudo apt install python3-numpy

If you did not notice missing numpy, then during bitbake you will get error "build No rule to make target 'drivers/elphel/x393.o', needed by 'drivers/elphel/built-in.a'. Stop." in that case you need to install numpy, re-run setup.py (make sure numpy error is gone) then re-create linux kernel links during next build by erasing old ones:

bitbake linux-xlnx -c clean

and re-running

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

When building php: configure: error: zip support requires ZLIB. Use --with-zlib-dir=<DIR> to specify prefix where ZLIB include and library are located

sudo apt install zlib1g-dev

Compare built vs deployed software versions

cd elphel393
./check_versions.py root@192.168.0.9

check_versions.py output in terminal (web-393 revision on PC is ahead of the one installed on the camera)
