1. Software Resources
Along with the MYD-C437X-PRU development board, we provide a SDK for developing an embedded Linux system on MYD-AM437X-PRU development board, it includes the fundamental cross compile toolchains，source code of U-boot, Kernel, drivers and test applications of all the peripheral modules.
The content of SDK for Linux is in the directory 05-RTOS_Source of our release package. It is shown as a table below.
