IsolarAB exports arxml to Matlab/Simulink to generate the model and configure the memory partition
This article uses a simple example to illustrate how to import the SWC arxml designed by Isolar into simulink to generate a model, and specify that the code generated by simulink has memory partition information. The SWC created in this article is called ECAS_Sensor_SWC. Its main function is to process sensor signals and pass them […]

Disk partitioning, formatting, verification and mounting —- fdisk, mkfs, mount
Disk partitioning, formatting, verification and mounting Disk management is very important. When we want to add a new disk to the system, we should perform the following steps: Divide the disk to create usable hard disk partitions (fdisk/gdisk) Format the hard drive partition to create a system-usable file system (mkfs) Check the newly created file […]

SOTA implementation based on Aurix TC3xx SWAP mechanism (A/B partition)
With the continuous expansion of chip resources, the diversity of App (Application) upgrade methods has increased. For example, the SOTA (Software Updates Over The Air) to be discussed in this article uses the Aurix TC3xx SWAP mechanism to make App upgrades more convenient. This article discusses some key issues in implementing SOTA: Aurix TC3xx memory […]
