Development Kit¶

Pre-Built Images¶

The following is a link to pre-built binaries for the development SD card image for the SOM variants. This will work with the FPGA or non-FPGA variants. It includes the preloader, uboot, and root filesystem.

Note: SD-Card Image requires a 16GB+ sd card.

Description	Location
Reference Micro-SD card Image	tisdk-rootfs-image
Reference Linux Developer Toolchain (based on TI's AM57xx PROCESSOR-SDK-LINUX)	arago-2019.11-armv7a-linux-gnueabi-tisdk.sh

For flashing the Micro-SD card, we recommend using balenaEtcher .
