automotive software and its tool-chain

why this repository

Because I am not powerful so I decided to develop tiny but smart part of automotive software based on open source, and create a general AUTOSAR & Automotive Software study environment.

As below picture shows, it was an virtual cluster based on AUTOSAR and can be simulated on Windows and Linux.

Key Point

1. BSW

1.1 Integrated ArcCore AUTOSAR 3.1 BSW

Communication: Can(CanFD) CanIf PduR Com SoAd J1939Tp
Diagnostic: CanTp Dcm DoIP Dem
System: EcuM SchM
Memory: Fls Fee Eep Ea NvM MemIf

1.2 AS Mini BSW

Mainly for the purpose to create a small footprint bootloader with all of the code implemented by me.

Diagnostic: CanTpMini DcmMini

2. OS ASKAR - Automotive oSeK AutosaR

This RTOS ASKAR is designed according to OSEK/VDX OS223 by taking a reference of a lot of other open source RTOS, generally, the bwlow is the list:

For the purpose that to be able to run most of the common applications which are based on posix, a series of posix APIs have been implemented based on the ASKAR OSEK tiny core.

posix threads
posix semaphore
posix mutex and condition
posix message queue
posix signals

3. BSW configuration tool

This GUI tool is the one from OpenSAR which is also developed by me, the GUI can be automatically created from xml.

4. AUTOSAR & LINUX communication

5. Lua & Python Integrated

support CAN device by lascanlib or pyas: CANcaseXL, PeakCAN, SocketCAN, ZLG USBCAN
support miscellaneous device by lasdevlib with the smae API interface "open/read/write/ioctl/close": rs232
a powerful python as.one.py tool: Dcm Xcp Bootloader and others.
a powerful third party RTE tool integrated: cogu/autosar

6. aslinux simulation environment on QEMU

Now use one makefile to bring up the QEMU AGL environment.
very simple and easy, with one single Makefile to build out the kernel and the rootfs, and a shell script to kick off the qemu virtual machine to execute that kernel and mount that rootfs.(for details check my github.io page on category linux)
aslinux build step

git clone https://github.com/parai/as.git
cd $(patch-to)/as/release/aslinux
mkdir build
cd build
ln -fs ../script/vexpress-ca9.mk Makefile
ln -fs ../script/run-vexpress.sh run.sh
make all
./run.sh
# if aslua want to be used
cd $(path-to)/as/release/aslua && make 31 && make 33 
cp out/arm.exe $(path-to)/as/release/aslinux/build/out/rootfs/usr/bin/aslua -v
cp /usr/arm-linux-gnueabi/lib/*.so* $(path-to)/as/release/aslinux/build/out/rootfs/lib -v
# then the sdcard need to be rebuilt
cd $(path-to)/as/release/aslinux/build && make sdcard

7. Other 3rd part package

LWIP
afbinder/websock
qemu PCI sample driver: asnet ascan asblk
FatFS
lwext4
libelf: an OS independent ELF library for ELF loading&executing.
LVGL:Littlev Graphics Libraray
