automotive software and its tool-chain

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.

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

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

• Diagnostic: CanTpMini DcmMini

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:

• toppers_osek
• FreeOSEK
• FreeRTOS
• ucos ii
• toppers-atk2
• contiki
• trampoline
• rtthread

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

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

• virtio
• remoteproc
• rpmsg
• virtio ring buffer

• 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

• 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

• LWIP: about text:133Kb, data:11Kb
• contiki-net: about text:54Kb(including the protothread), data:4Kb
• 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
• DTC/LIBFDT
