AM3352: SD card boot

Guru 10095 points
Part Number: AM3352

Hi Sitara support Team,

The customer's board using AM3352 is connected via a Board to Board connector to SD card slot mounted on another board.

The total wiring length is about 70 mm, but are there any restrictions on the wiring length?

Since 5 out of 10 boards have failed in SD card boot, I would like to check if the wiring length can be the cause.

Best regards,
Kanae
