Configure MCAL and HWIO using Tresos acg8 for 3 different Daimler truck front camera projects using Renesas V3M, V3H and ST SCP584B controllers. Develop custom software for non AUROSAR modules such as die µC temperature monitoring, external DDR voltage management and DMA configuration mainly between external flash memory on QSPI and external RAM memory. Later as part of the functional safety team I had to develop the configuration for the IRQ monitor module and then fix all the compiler warnings, MISRA, company specific code quality rules and finally update the Doxygen comments and schematics.

5/2014 – 12/2015

Project task: Develop a wrapper layer between the basic software and application software for a mechatronic actuator module (automatic gearbox). The wrapper layer should allow the replacement of an old first generation hardware and basic software with second generation ones and keeping the first generation application software. With this strategy only the wrapper layer has to be validated and not the entire BSW v.2 and ASW v.1.
Duties: Check which interfaces, functions and global variables have identical behavior and wrap those which have changed and verify if they used in the same OS tasks. Configure the Mcal to enable an optional external EEPROM, remap the DTCs, and simulate the old state machine statuses, L2 and L3 safety strategies.
