JC 01:47 PM PCB Development: RE: eMMC support for MitySOM AM572x

Per this e2e post, it should be okay to use 1.8V signal levels with an eMMC.
https://e2e.ti.com/support/processors-group/processors/f/processors-forum/827480/am5718-emmc-at-1-8v
The eMMC_RSTn signal can be connected to any gpio on ...

SS 07:25 AM PCB Development: RE: eMMC support for MitySOM AM572x
Hi Jonathan,
We designed an eMMC circuit using *MTFC16GAPALBH-AIT*. As per the data sheet of MitySOM MMC2 signals are 1.8V level.
we follow the AM572x-IDK schematic design for designing eMMC circuit. But there an eMMC_RSTn signal is ...

Thanks, I'll look into it. I'm pretty sure that's incorrect. Jonathan Cormier
SS 05:49 AM PCB Development: RE: Design support for USB for use with AM57x SOM
Hi Jonathan,
*1. For USB2, it is mentioned that voltage level is 1.8V. We need to connect these signals to USB3.0 StdA Connector
Can you point me to the documentation your referencing?*

Schematic review:
* Both schematics are using VUSB_VBUS1 as a net name. One of them is probably supposed to be VUSB_VBUS2.
* The SOM already contains 0.1uF caps on the USB1_SSTX_P/N lines, I don't believe they should be on the baseboa...
