Flash bootloader supports customised Linux ECU flashing

January 10, 2017 // By Graham Prophet
Vector Informatik (Stuttgart, Germany) is supplementing its portfolio of basic software products by adding a flash bootloader for Linux-based ECUs. Developers gain a simplified process for reprogramming these ECUs according to OEM-specific requirements.

The code enables reliable updating of shell scripts and graphic data as well as configuration and operating system files. Current infotainment and telematic controllers feature high-resolution graphics and comprehensive connectivity. In order to handle these high performance requirements, operating systems such as Linux are now used with these embedded systems. Vector’s Flash Bootloader for conventional and AUTOSAR-conformant ECUs has now been extended for POSIX-compatible operating systems such as Linux. Communications with the flash tool are performed over Ethernet as per to ISO 13400-2 (DoIP) and in accordance with OEM-specific download specifications.

The bootloader is based on the Linux runtime environment and thereby enables file-based software downloads. This also lets users update individual sections of software - in a time-saving and very efficient way - during development, in production and in vehicle service. An additional advantage is that security options effectively protect ECUs with sensitive vehicle data.

The Vector Flash Bootloader is available for all established automotive OEMs and commonly used embedded Linux systems in the automotive field. If necessary, the basic software can be used for other POSIX-compatible operating systems.
