TMDSEMU110-U: TI 20-pin to Arm Cortex 10-pin converter adapter

Daniel Nanto

Part Number: TMDSEMU110-U

I saw on another post that you do not sell replacement adapters. One of the vendor links in that post is broken, and the other costs more than buying an entirely new TMDSEMU110-U. I'm willing to make my own PCB adapter. Do you have a schematic available for the adapter requirements? I noticed a few resistors on what's left of my broken adapter, and I want to make sure I make it to specifications.

Hello Daniel,

Here is a page for all of the information regarding JTAG signal pinouts and different specifics for each connector type: https://software-dl.ti.com/ccs/esd/documents/xdsdebugprobes/emu_jtag_connectors.html

The user guide provides a table for mapping the JTAG signals from cTI to CM10 in Table 4. CTI to Other Adaptor Pin Mapping.

To create your own adapter board, you would only need to ensure that the mapping follows this table. There is no need for resistors on the adapter board.

The diagram below shows all resistors recommended between the target device and the emulation header.

For additional information, refer to the Emulation Technical Reference Manual.

Regards,

Erik
