- JC 11:02 AM Software Development: RE: ICE cannot be connected to SOM without FGPA
- Glad to hear it.
- MF 01:56 AM Software Development: RE: ICE cannot be connected to SOM without FGPA
- By shorting pins 4 and 8, we were able to connect the ICE to the CPU.

- On J4, the TDIS signal is supposed to be connected to GND. I tested the connection on a module by shorting pins 4 and 8 using tweezers and was able to connect to the ARM over JTAG.

- I was able to reproduce your results on a 5746-PX-4AA-RI Rev2A. We will look into this.
I am having trouble making ICE connections with the following SOM
・5728-PX-4AA-RI
・5729-PX-4AA-RI
・5746-PX-4AA-RI
In addition, the ICE connection is working for "5749-PM-4AA-RI" by the same operation.

- 1.The J1 and J3 connectors of "MitySOM-AM57 (non-FPGA variant)" 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.The J1 and J3 connectors o...

- Hello,
To be clear, this information is for the MitySOM-AM57 (non-FPGA variant). I am sorry I was thinking you were referring to the FPGA variant of the MitySOM-AM57F.
For the pins in question:
J1-99 (AB16) - the SOM includes... - MF 01:58 AM PCB Development: RE: Unconnected pins, board dimensions and hole positions
- > If you have specific pins that are of concern, please let us know which ones.
Is it okay to leave the following signals open when not in use?
J1-99 (AB16)
J1-101 (D21)
J3-8 (C25)
J3-10 (F17)
Looking at the AM5728 (TI) dat...

- Thanks, Jon!
Tom - JC 02:01 PM PCB Development: RE: Is the USB SS connection correct?
- Thanks for pointing that out. Posted updated schematics and noted them on this new wiki page. https://support.criticallink.com/redmine/projects/mitysom_am57x/wiki/Development_Kit_Revision_Information
- SS 08:49 AM PCB Development: RE: Is the USB SS connection correct?
- Hi,
Can you please share the schematic design file location in the website. I am getting old schematic design from the "files" link.
With regards

- Hello,
I had edited my previous post to correct. Yes it is:
Correct: AM572x (USB_TXN/P0)
The 80-001317RH-5_SCH_RevA.PDF should properly connect the USB-3. You can assume it is OK.
