The development board provides a debug interface to the MCU through the TC2050-IDC 10-pin JTAG connector (CN3). The carrier board adapts the TC2050-IDC connector to a standard 10-pin and a 20-pin Arm JTAG connector, and is designed for XDS110 and TM4C129 programmers.

| Name | Signal | Color | Active | Expected at power-on |
|---|---|---|---|---|
| D4 | AM261_WARMRSTN (warm reset deasserted) | Green | High-active | ON |
| D7 | PORZ (power-on reset deasserted) | Green | High-active | ON |
| D8 | User LED (GPIO140) | Green | High-active | OFF |
| D9 | CORE_PG (input supply and +3V3 output rail valid) | Green | High-active | ON |
