2.3.2 DIP Switches
The AM4100 is equipped with two DIP switches, one 4-bit general purpose DIP switch, SW2,
and one 2-bit IPMI configuration DIP switch, SW3, both situated on the reverse side of the
board. For further information, refer to chapter 4.1, Configuration of DIP Switches.
2.3.3 JTAG/Debug Interface
The AM4100 provides several onboard options for hardware and software debugging, such as:
• Four bicolor debug LEDs for signaling hardware failures and POST code
• An optional debug (processor JTAG) connector J5 (type: Hirose DF19G-20P-1H) is in-
cluded to facilitate software debugging using an emulation probe
The following table provides pinout information for the debug connector J5.
