Firmware recovery
8.1
Overview
If after power-on the
SYS
LED (see position
(5)
in section
page 22]) is flashing yellow and green at a rate of 1
Hz, the device is in boot mode. The firmware file of the netTAP
NT 151-
CCIES-RE
is missing or defective. In this state, the device cannot be
operated and the firmware needs to be recovered either by SD memory
card or via USB.
Using SD memory card to reset the device to its factory settings
When using the SD memory card, the file system inside the device will be
reformatted and all existing firmware, configuration or IP address files will
automatically be deleted. The device will thus be reset to its “factory
settings”. Note that by this method, only a so-called “base firmware” is
copied from the SD memory card to the device, enabling the subsequent
downloading of the “regular” full firmware by SYCON.net via USB
connection. This means that after using the SD card, you will have to
establish a USB connection between the netTAP and your configuration PC
in order to download the regular firmware and a new configuration to the
device with SYCON.net.
Using USB and ComProX2 to reset the device to its factory settings/
recover the firmware
On the other hand, if you are using the Hilscher
ComProX2
tool via USB,
you can directly access the file system of the netTAP and overwrite the old
defective firmware file with a fresh firmware file. Here, you can directly
download the “regular” firmware to the netTAP without first having to use
the “base firmware” – as it is the case when using the SD card.
Since
ComProX2
allows you to format the whole file system or to erase or
download only individual files, you can decide for yourself whether you
want to reset the device to its factory settings (erase all files and then
download firmware) or whether you want to preserve old configuration files
inside the device and only erase the old defective firmware file by
downloading new firmware file, thus performing only a “firmware recovery”
instead of a “factory reset”. Note, however, that a defective firmware most
likely causes corruption also of the file system, thus making a re-formatting
of the file system strongly advisable before downloading the new firmware
file. Therefore it is recommended to completely reset the device to its
factory settings instead of just exchanging/recovering the firmware.
