Use only 16 Bit DDR Data Width on Zedboard

Former Member
Former Member over 12 years ago

Hello everyone,

Zedboard uses two DDR3-SDRAM chip with a width of 16-Data Bits each. So there is a 32 Bit/566 MHz DDR3 interface with a good performance - no doubt about that.

For my application it is maybe sufficient to use only one DDR chip with 16 Bit databus. But I first want to evaluate the performance on the Zedboard.

Ist it posssible to use only one of the DDR memory chips on Zedboard?
Of course I can configure the memory controller in Vivado to use a 16 Bit Databus, but are there any hardware restrictions for my approach on Zedboard?

Regards,
SAT

    I tried that..
    Started writing from 0x00100000 to 0x0000FFFF.

    But, the console was printing the details of FSBL and other details instead of reading the required values..

    What would be cause of this?
