The SR6P7G7C7 is built on ARM® architecture technology and integrates innovations that are important for today’s and tomorrow’s automotive applications. SR6P7G7C7 integration MCUs have been designed to meet the requirements of domain controllers and ECUs with high integration requested in the architectures of connected update-able automated and electrified cars.
By default only Cluster0_Core0 (Cortex-R52) is running. To enable all other Cortex-R52 cores and DME and DSPH cores establish a debug connection to Cluster0_Core0 (Cortex-R52) as during the connection procedure all other Cortex-R52 and DME and DSPH cores get enabled.
During connect 16kB of ECC RAM at 0x60000000 get initialized, which is mandatory for flash programming. The JLinkScript file that is used for the RAM init can be downloaded here and adapted if further RAM needs to be initialized. To increase the size of initialized RAM, editt within the "InitTarget" function the parameters of the "_InitRAM" function call. The first parameter defines the number of kilobytes and the second parameter the start address of the RAM for init. To initialize other RAM areas the "_InitRAM" function can be duplicated with another start address.

Flash programming of all below listed flash regions is done through Cluster0_Core0 (Cortex-R52). All other Cortex-R52 cores only allow debugging. The flash controller of the SR6P7G7x has no explicit erase function. When reprogramming flash an explicit erase before programming is not necessary. Already programmed flash can be directly reprogrammed.
On-Chip Memory Regions
The internal flash is divided into 13 different regions:
