TDA2PXEVM: Changing MMC for SD card reading in PSDK3.5

Nicolas Rausch

Part Number: TDA2PXEVM

Hey,

I am using PSDK3.5 with TDA2PXEVM. I want to change the MMC instance from 1(which is currently used) to 3, to test if file writing with 8bit data bus will accelerate writing frames to sd card.

So far I can`t find where to change the MMC and if it is possible at all.

Where can I adjust the settings to use MMC3?

Also I would like to increase the clk frequency from 10MHz to 19MHz in order to speed up the writing process. Does this work?

regards,

Hi Nicolas,

Are you using TDA2P EVM or custom hardware?

Hi Nicolas,

On TDA2P EVM it is not possible to use MMC3 as there is no physical connection.

Please refer to EVM schematics for the same.

Hi,

I haven't heard back from you, I'm assuming you were able to resolve your issue.
