+Prepare 1 female-to-female jumper wire. Orient the board as shown below, with the USB and Ethernet ports at the bottom and the button header at the top. Count positions from the left end of the header toward the right in this orientation.

**issue:** All eight local image references point to files that are not added anywhere in this diff, so the button-header, flashing-tool, and Weston screenshots render as broken images in both reports.
**Suggested fix:** Add the referenced PNG files under `CoM260 Kit/BuildRoot/`, or remove/update the references to files that exist.
</issue_to_address>
### Comment 2
<location path="CoM260 Kit/BuildRoot/README.md" line_range="3" />
<code_context>

+sys: buildroot
+sys_ver: "1.0.7"
+sys_var: null
</code_context>
<issue_to_address>
**issue:** The support-matrix metadata advertises system version 1.0.7 while the boot evidence in both reports identifies the running system as `k3-br-v1.0.6`, so the matrix labels a test result with a different runtime version than the one shown by the report.
**Suggested fix:** Reconcile the release metadata and runtime version, or set `sys_ver` to the actually verified version and explain the image-package discrepancy separately.
```suggestion
sys_ver: "1.0.6"
```
