Warranty
Hilscher Gesellschaft für Systemautomation mbH hereby guarantees that
the software shall run without errors in accordance with the requirements
listed in the specifications and that there were no defects on the date of
acceptance. The warranty period shall be 12 months commencing as of the
date of acceptance or purchase (with express declaration or implied, by

2.3 Operating elements
2.3.1 S300 - DIP switches for selecting boot mode and PLL clock speed
For identifying the switches on the board, see position (1) in section
Positions of interfaces and operating elements [}page12].
These switches allow you to:
·select the boot mode
– select the standard boot mode
– enable the console mode
– enable the alternative boot mode
·set the PLL clock speed for the Dual Cortex-A9 to either 400 MHz or
600 MHz
Boot mode
The ROM Code of the netX 4000 features an integrated bootloader that
automatically recognizes the selected boot mode and the initial state of the
device after reset.
The user can select a certain boot sequence option by setting the switches
No 1, No 2 and No 3 of S300 accordingly (see table S300 boot sequence
configuration [}page16]).
Example: If boot sequence option 1 is selected, the ROM resident
bootloader searches for a bootable image in the SQI Flash. If no image is
found, the bootloader continues its search according to the sequence. If the
loader cannot find any image in the sources, it automatically enters the
console mode to enable the initial provisioning of a firmware.
Standard boot mode
In standard boot mode, the ROM resident bootloader searches for a
“standard” bootable firmware image in the boot sources according to the
chosen boot sequence option (see table S300 boot sequence
configuration [}page16]).
Console mode
The purpose of the console mode is to enable the handling of firmware
programming – such as the download of a firmware to the SQI Flash – via a
USB connection (USB socket X301 of the board) from a development PC
(Flasher Tool from Hilscher).
For information about how to use the Flasher Tool from Hilscher for
the NXHX 4000-JTAG+, see Getting Started document NXHX
4000-JTAG+ Development Board, DOC171004GSxxEN.
Note:
Temporarily connecting RDY to ground (S300-E) while carrying out a
reset cycle forces the device into console mode regardless of the
initial state and boot mode settings.

Alternative boot mode
Note:
The alternative boot mode is not yet supported by the initial version
of the netX 4000.
It will be available on the final version of the netX 4000 in serial
production.

For identifying the button on the board, see position (11) in section

T301 Signal Connects to Function
JT_RESET_IN# GND Resets the netX
Table9: T301 - Reset button
Important:
The first “engineering sample” version of the netX 4000 has a glitch
concerning the RST_IN# signal (i.e. the JT_RESET_IN# signal of
the T301 reset button on the NXHX 4000-JTAG+ board).
The current workaround is always using the POR# signal (i.e. the
T300 power-on reset button on the board) instead of the RST_IN#
signal for achieving a power cycle.
The POR# signal (i.e. the T300 button) resets the full SoC including
PLL and debug settings, in contrast to the RST_IN# signal (i.e. the
T301 button).

Down +3.3V via 10 kΩ Enables the usage of the NXHX-FTDI adapter module
at the X1300 host interface connector, which provides
access to the serial Dual-Port Memory (SPM) interface
from PC or laptop via USB.
Note: If this setting is used, the on-board SDRAM
cannot be used, due to pin sharing restrictions.
Up GND via 10 kΩ The on-board SDRAM can operate in 32-bit data mode.
If this setting is used, the NXHX-FTDI adapter module
cannot be used, due to pin sharing restrictions.
