AM68 Starter Kit (SK) is a low cost, small form factor board designed for TI’s J721S2/AM68 SoC. TI’s J721S2/AM68 SoC comprises of dual core A72, high performance vision accelerators, hardware accelerators, latest C71x DSP, high bandwidth real-time IPs for capture and display. The SoC is power optimized to provide best in class performance for industrial and automotive applications.
Refer below link to J721S2/AM68 Technical Reference Manual for further details: http://www.ti.com/lit/pdf/spruj28
AM68 SK supports the following interfaces: * 16 GB LPDDR4 RAM * x1 Gigabit Ethernet interface * x1 USB 3.1 Type-C port * x2 USB 3.1 Type-A ports * x1 PCIe M.2 M Key * 512 Mbit OSPI flash * x2 CSI2 Camera interface (RPi and TI Camera connector) * 40-pin Raspberry Pi GPIO header
This series of patch add initial support for AM68 starter kit. Design files can be referrred from https://www.ti.com/lit/zip/SPRR463
