3.8.9 Front Panel Push Buttons
The board houses two push buttons on the front, which are recessed to prevent pressing by
mistake. The two buttons are a reset button (Reset) and a recovery button (Recov.). The location
of the buttons can be found in Figure 4. Information about the buttons can be found in Table 25.

Recov. FORCE_RECOVERY_N L10
To start the NVIDIA ® Xavier™ in recovery mode, the recovery button needs to be
pressed when the module receives power or during reset. As the BMC might be
reset (see CLI command “config”), starts the bootloader first and after that powers
the module, the recovery button needs to be held until the BMC provides power to
the module. The moment the module receives power can be identified by the Power
LED (see chapter 3.8.8).
3.8.10 BMC Programming header
The JetKit-3010 has an on-board BMC programming interface (BMC Prog). This interface is only
required as a backup programming option in case the bootloader is corrupt and needs to be re-
flashed.
For regular Firmware updates, please see chapter 3.3.3.
The pinout of the BMC Prog header can be found in Table 26.

5 ICP_PGC
This interface is dedicated for a Microchip PICkit 3.
Please note that an extension cable might be required to be able to plug the PICkit.
Use this programming interface only after consulting Elma.
Programming requires further configuration and a specific configured bootloader file
is required. This interface should not be used except cases when the bootloader gets
corrupt!
