USB storage works sometimes

chuey714 — Wed, 13 Sep 2017 15:52:10 GMT

Hi all,

We are working on our custom board using an iMX7D and are having some issues with certain USB storage devices. Some storage devices work and some throw a bunch of errors, not always the same. Also, as far as we can tell, non storage devices work fine.

We are using TPD4S214 for VBUS supply and ESD. Here are some examples:

Working stick (SanDisk Cruzer 2GB):

Hi Juan

reason for unstable operation may be poor signal due to board noise/layout

problems. May be recommended to check below documents for available adjustments:

I.MX6/7 Series USB Certification Guide
https://community.nxp.com/docs/DOC-105609
AN4589 Configuring USB on i.MX 6 Series Processors
