CCS/AM5718: DDR frequency in GEL file

NICK

Part Number: AM5718

Tool/software: Code Composer Studio

Currently, we are running some examples from SDK with idk571x_evm board. The example works fine.

I see the ddr3l works at 666MHz set by AM571x_ddr_config.gel file located at ../emulation/boards/am571x/gel/ .

We would like to config the DDR3L memory frequency from 666MHz to 400MHz. We followed the steps of EMIF tools and finally get the register values for gel.

We copied the register values to gel file, but CCS could not load successfully.

Could you tell me the right steps on how to change the AM571x_ddr_config.gel file from 666MHz to 400MHz? Thanks!

Hi Nick,

I suggest you to take a look on the at the linked below guide about adding GEL files to a target configuration v5 (the tutorial is no directly related to am5718):

Hi Tsvetolin,

Thanks for your support.

I'm sorry that I didn't make it clear.

The DDR3 gel configured at 666MHz which provided by SDK works fine, it is successfully added, loaded and run on CCS . My question is ,where can I get DDR3 gel configured at 400MHz or how can I create it?

Thanks!

Nick
