The Linux Automation Test Automation Controller (LXA TAC)[1] is an embedded software development tool built around the Octavo Systems OSD32MP15x SiP. The device contains an eMMC for storage, a DSA-capable on board ethernet switch with two external ports, dual CAN busses, a power switch to turn a device under test on or off and some other I/O. As of now there are two STM32MP157 based hardware generations (Gen 1 and Gen 2) that have most of their hardware config in common. In the future there will also be a STM32MP153 based hardware generation.
