OMAP4 GPMC Interface

Midson

Hi, Is there any OMAP4 Development platform with GPMC interface? The Pandaboard is having the GPMC. But both address and data are multiplexed. I am looking for development platform with dedicated address lines (like in OMAP3 EVM). Any idea about Blaze Tablet 2 device, Is it having GPMC interface? If not as proper interface, is it possible to make a break-out board to take it out?

Thanks

    Any help on this? As it is 2K USD device, If there is no GPMC interface, it is no use for me. Thanks.

    Hello Midson,

    On OMAP44xx, Address and Data lines are muxed for bits[0:15] to reduce ball count. On Blaze you will not be able to access the GPMC bus, because we using the SDMMC2 pins muxed behind some of the GPMC pins to connect to eMMC memory and other functions. This applies to Blaze, Blaze Tablet 1 and 2 platform. On Panda you can access the GPMC bus voa the Expansion connectors. Please note that the only dedicated address lines on OMAP44xx are Address[16:25].

    Regards
