FWIW, the datasheet refers to a "Hardware Design Guide for JacintoTM 7 Devices" but no such document exists.

Hi Lemmiwinks,

The link above for the AM68A datasheet shows a table called "Table 6-69. MMC1 Timing Conditions" which has the trace length requirements.

You can find it on pg 216-217.

Best Regards,

Matt
