Freescale i.MX27ADS
Reference boards/OEM boards enabled:
The Freescale i.MX27 LinuxLink can also be used as a starting point for Linux development for designs derived from the Freescale i.MX27 Application Development System (ADS).
Notes:
Complete peripheral support for Freescale i.MX27 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 Freescale i.MX27 processor has been validated on the i.MX27ADS reference board from Freescale. The ADS system used by Timesys consists of three boards. The base board that hosts most of external connectors, an i.MX27 processor card, LCD display module and a keypad module, all attached to the baseboard.
