TM4C123GH6PZ: TM4C123GH6PZI basic

Hello albgarc,

1-) Is the JTAG connection to connector P1 correct?

Yes.

2-) Can I use in P1 a 5x2 connector with pitch 1.27 mm (FTSH-105-01-L-DV-K) to debug with the XDS200?

Should be fine from what I can see.

3-) In this case do I need adapters (check image below)?
4-)How can I connect the XDS200 debugger directly to the board without adapters (check image below)?

Yes. XDS200 ships with these adapters included. 

The XDS200 comes in a package consisting of:

• XDS200 debug pod
• TI 20-pin to TI 14-pin converter adapter
• TI 20-pin to Arm 20-pin converter adapter
• TI 20-pin to Arm Cortex 10-pin converter adapter <--- This is what you can use.
• USB2.0 cable
• Quick start guide

If you don't want to use an adapter you could use the TI 20-pin layout but most customers just use the adapter to take advantage of the smaller header as the 20-pin header does not give added functionality so you gain nothing for the added space used.

5-) Do you see any problem in electrical design (power suppy, gnd, ...)?

Yes, you are missing the 100 ohm resistor between Pin 1 and VDD.

You are also missing the 10k ohm pulldown resistor on TDO.

See this image (the 33 ohm resistors can be omitted):

That image comes from our JTAG user's guide for TM4C: https://www.ti.com/lit/pdf/spma075

6-) Is it possible to debug the TM4C123GH6PZI with an XDS100?

Yep! XDS100 works with it just fine. That said, I'd recommended the newer XDS110 personally as we don't produce XDS100 anymore to my knowledge.

The XDS110 will come with the same adapters as the XDS200.
