XDS Debug Header (J4)

The XDS debug header (J4) provides debug access to the AM261-SOM-EVM. This header is used when the controlSOM is used in SOM Configuration 2 or Configuration 3. The XDS debug header is compatible with the XDS110ISO-EVM. Table 2-4 provides a pinout of the J4 header.

CAUTION:

The XDS debug header (J4) is only compatible with the XDS110ISO-EVM. Do not plug in any other debug probe directly into this header.
