The XDS debug header (J4) provides debug access to the AM261-SOM-EVM. The XDS debug header is compatible with the XDS110ISO-EVM. Table 2-3 provides a pinout of the J4 header.
The XDS debug header (J4) is only compatible with the XDS110ISO-EVM. Do not plug in any other debug probe directly into this header. See Section 2.9 for information on using other debug probes with the controlSOM.
