Fix: Enable USB JTAG serial for Jade on ESP32S3
Set CONFIG_JADE_USE_USB_JTAG_SERIAL to 'y' in the Waveshare S3 touch LCD2 defaults to enable USB JTAG serial support for Jade on the ESP32S3 target.
What changed, and why it matters
This commit changes one configuration line for a specific Jade hardware variant (Waveshare S3 touch LCD2). It turns on the USB JTAG serial feature, which is a normal debug/serial communication option for ESP32S3-based devices. There is nothing in the commit message, title, or diff that indicates a security fix, vulnerability, or malicious change. It appears to be a hardware-enablement or functionality fix.
No security action required. Treat as routine hardware configuration change. If USB JTAG serial exposure is a concern for a specific threat model, review physical-access policies and whether the interface is left enabled in production firmware, but that is outside the scope of this commit evidence.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The patch adds CONFIG_JADE_USE_USB_JTAG_SERIAL=y to configs/sdkconfig_display_waveshares3_touch_lcd2.defaults for the ESP32S3 target. This enables the USB JTAG serial console/interface on that specific Jade board configuration. The change is a single Kconfig default and does not modify cryptographic, authentication, firmware-update, or secure-boot code. No security relevance is stated by the vendor.
