Software

The AM623 and AM625 are capable of supporting high-level operating systems, including both Linux and RTOS. There are Software Development Kits (SDKs) created for both. The SDKs are feature-rich and allow you to easily begin your software development on these processors with integrated demonstrations and examples, as well as long-term stable kernel support on the ARM Cortex-A53 cores. There is also SDK support for the ARM Cortex-R5F core, including FreeRTOS. For development help, look to TI’s Developer Zone.

Scalability

These processors offer scalable performance and feature sets to cater to a wide range of application needs. All AM623 and AM625 devices are pin-to-pin compatible, allowing developers to select the appropriate model for their current system and to easily adapt as their requirements change. There is a single Software Development Kit (SDK) for the entire AM623 and AM625 families. This simplifies the development process by providing a unified platform for software development, reducing time and effort spent on software integration and testing when using different processors. This scalability maintains that developers can use the processors across different projects, including when moving from the simpler AM623 or the more complex AM62P, while reducing development time and costs.

Security

The AM623 and AM625 processors have several security features to support device protection and help meet new security regulations. The security features include a secure enclave to isolate the security functions from the rest of the device, securely enabling features like secure boot with hardware-enforced Root-of-Trust. The devices have extensive firewall support and a dedicated security DMA and Inter-Processor Communication (IPC) for isolation and secure storage support, as well as cryptographic acceleration. The security subsystem includes an HSM core for HSM stack integration. The security subsystem employs ARMs Trustzone technology to provide a Trusted Execution Environment (TEE) via OP-TEE. AM623 and AM625 are security-centric to enable you to protect your device, system, and data.

Evaluation Module

The starter kit Evaluation Module (EVM) is the SK-AM62B-P1. The SK-AM62B-P1 is a great fit for those looking to develop automotive and industrial applications. The SK-AM62B-P1 allows you to use and test the AM623 and AM625 and explore the broad range of peripherals before developing your design. The SK-AM62B-P1 has multiple display connectors for two displays, M.2 key E interface to support for WiFi and Bluetooth capabilities, 2 Ethernet ports, and UART connections. The SK-AM62B-P1 also has a software development kit (SDK) to start you Linux
