- MW 08:07 PM PCB Development: RE: Unconnected pins, board dimensions and hole positions
- Hello.
1. Generally speaking, all of the MFIO pins are direct connects to the AM57xx CPU device and if they are unused in your design it is safe to leave them not connected. The Ball numbers are included in the table and can be cross...
Posting on behalf of customer:
1.The J1 and J3 connectors of MitySOM-AM57 are described as “MFIO” for “Type”.
"If this pin is not used, can it be left unconnected?"
(Table 6, Table 7 in MitySOM-AM57_datasheet.pdf)
2.Is it okay...

- Hi,
For testing IEEE 1588 H/W time stamp application, we included DP83640 in our circuit. Since DP83640 doesn't have 1.8V I/O level, we used Voltage level converters TXS0104E (Bidirectional, Push-pull and Open drain compatible) and SN...

Per this e2e post, it should be okay to use 1.8V signal levels with an eMMC.

- 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 ...

- 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... - Hi,
We need to integrate one USB 3.0, one USB 2.0 and one Debug USB with our application system.

2. But for USB1...

We have to develop a QT application for our AM57x Development board. which version of QT creator is supported with AM57x ?
Is there any example programs and getting started tutorials for the same.

We have some doubts regarding designing the Ethernet circuit using DP83640(For PTP hardware time stamp).
