- 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.

- JC 04:03 PM Software Development: RE: ICE cannot be connected to SOM without FGPA
- 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)

- 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

- 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.

Will this one also be corrected as follows?
Incorrect: FPGA (USB_TXN/P0)
Correct: AM572x (USB_TXN/P0)
- JC 02:22 PM PCB Development: RE: Is the USB SS connection correct?

- Hi Masayoshi,
It looks like there is an error in the datasheet.
Pin 33/35 are connected to AC11/AD11 on the FPGA (USB_TXN/P0), with AC coupling (DC blocking) capacitor.
Pin 27/29 are connected to AF12/AE12 (USB_RXN/P0) as straig...
The J3Pin-Out (Table 7) of the MitySOM-AM57 System on Module data sheet describes the USB3.0 SuperSpeed terminals as follows.
Pin27 AC11 USB1_SSRX_N
Pin29 AD11 USB1_SSRX_P
Pin33 AF12 USB1_SSTX_N(2)
Pin35 AE12 USB1_SSTX_P(2)

- TC 01:57 PM PCB Development: RE: about MECHANICAL INTERFACE in AM57x DataSheet
- Thank you for pointing this out. We will repair the figure references in the next revision of the datasheet. In both cases the erroneous reference is to the figures directly below the text where the error appears.
https://www.criticallink.com/wp-content/uploads/60-000055-MitySOM-AM57_datasheet.pdf
On P29 and P31 of the DataSheet.
You find "Error! Reference source not found."
Please update document.
