Freescale i.MX31ADS
Reference boards/OEM boards enabled:
The Freescale i.MX31 LinuxLink can also be used as a starting point for Linux development for designs derived from the Freescale i.MX31 Application Development System (ADS).
Notes:
Complete peripheral support for Freescale i.MX31 derived integrated processors, or board support for other reference designs, might need to be sourced from manufacturers of the respective processors or reference boards.
Boards and Reference Distributions
LinuxLink software for the i.MX31 processor has been validated on the i.MX31ADS reference board from Freescale. The ADS system used by Timesys consists of three boards. The base board that hosts most external connectors, an i.MX31 processor card and a power management board mounted on the baseboard.
