LP-XDS110: Arm 10 Pin adapter replacement for connection with the XDS110 debug probe

Ruthrapathy K

Part Number: LP-XDS110

I have used XDS110 Debug Probe with Arm 10 Pin adapter(516441 Rev A) to debug the F2800157_48PHP. But the Arm 10 Pin adapter got broken accidentally (like the Pad are off the track). Please share the schematics and Pin mappings of that adapter

Hi,

We don't have the schematics publicly available, but the pin map between the Compact TI (cTI) 20-pin present on the XDS110 and the ARM Cortex 10-pin connector can be found at the table shown in the following page:

Hope this helps,

There are resistors which are present in the adaptor. Will it work if we do the direct pin mapping instead of using these resistors?

Hi,

The resistors are used to select the source of the Reset signal that is passed to pin 10 of the ARM 10-pin connector. The CTi-20 pin connector has two resets: pin 2 is the nTRST (to reset the JTAG Debug Subsystem) and pin 15 is the nRESET (the System Reset that initializes the whole board).

Since your device does not have a TRST pin, you should instead connect the nRESET signal.

Hope this helps,

Rafael
