4. Change the Software on TCPConv via USB Stick

4. Change the Software on TCPConv via
USB Stick
For the configurations mentioned in 3, it is necessary that TCPConv 2 always has a web
front-end accessible by the user. This may not be the case when for example the network
interface on TCPConv 2 is mistakenly configured or an application without web front-end is
for some reason running on TCPConv 2.
Under such circumstances, one can change the software on TCPConv 2 via a USB Stick
with correct software. Here the word "software" can refer to a Linux kernel, a whole Debian
File System, or an application.
4.1. Prepare the USB Stick
The USB Stick should use FAT format, NTFS is not yet supported. It is also desired that the
USB Stick had only one partition. In the coming versions, USB Stick with NTFS and/or more
partitions will also be supported.
The image files can be found under Image of TCPConv2DevPack.
4.2. Power up TCPConv with USB Stick plugged
If the USB Stick plugged has a correct certificate and a correct signature, TCPConv will
execute the main.sh script.
The whole operation could take quite a while when for example the whole File System must
be uploaded to TCPConv. After the script is executed, TCPConv will make a beep and blink
its information LEDs.
