AM2434: Design recommendations OSPI

Alex Paul

Part Number: AM2434

Tool/software:

Dear Experts,

Do we have any recommendations on Layout rules for OSPI-flash on AM243?

I have just seen some information on timing so far. Do we need to calculate the matching requirements ourselves or is there a good guide that gives detailed requirements on OSPI-routling for AM243 ?

Regards,

Alex

Hi Alex,

As answered in the below thread, these requirements are defined in the respective Timing Conditions table found in the timing sections of the datasheet. The recommendation is to follow the rules for high-speed design.

Below FAQ is what we have for OSPI/QSPI schematic design, commonly observed errors during schematic designs.
