On this page you are going to find all the necessary information to start from scratch to use the RidgeRun SDK on your DM6446 evaluation module (EVM). In the following sections we assume that you have already downloaded the DVSDK version for OMAP3X processor (this version is compatible with the DM6446) and that you have installed the toolchain 2009q1-203 from codesourcery as well as your DM6446 SDK following the steps on The RidgeRun installation guide.

Supported drivers

RidgeRun SDK's kernel has support for the following list of drivers for the DM6446 processor:

  • UART driver
  • I2C driver
  • GPIO driver
  • EDMA driver
  • NAND driver with 4-bit ECC, SLC/MLC, up to 4K page size support
  • MMC/SD driver with SDHC and SDIO support
  • SPI driver with EEPROM support (polled, PIO and DMA mode of operation)
  • USB driver with Host, Device and OTG modes; Supports USB Host/Device Mass Storage Class, USB Hub and HID clasess as well as USB Device CDC / RNDIS classes

Basic preliminary work

Installing the DVSDK

  1. Set the DVSDK binary as executable and set the required permissions.
     sudo chmod 777 dvsdk_omap3530-evm_4_01_00_09_setuplinux
  1. Install the DVSDK. For ubuntu versions different than Ubuntu 10.04 LTS 32-bit you will need to add the --forcehost argument to install it:
     ./dvsdk_omap3530-evm_4_01_00_09_setuplinux --forcehost

note: During the EZSDK installation process you will be asked for the toolchain's path, assuming that you installed it on /opt, the path that you need to provide is /opt/codesourcery/arm-2009q1/bin/
