7.2 Macintosh and Linux drivers
A Virtual Com Port driver kit for Mac and Linux can be obtained by following the link on our website
on the Support
Software download page.
In addition, one of our customers has written a Linux driver that will be included in the 2.6.25
kernel.
It can be found at www.kernel.org/pub/linux/kernel/people/gregkh/gregkh-2.6/patches/.
(Note that this is for information only, and this software was developed entirely outside Telegesis.)
8 Custom Firmware Development
If you intend to develop custom firmware to go onto the ETRX2USB you need to contact Ember to
obtain access to their suite of development tools and their stack. The USB stick contains an
ETRX2 module based on the Ember EM250 and a USB-to-serial bridge chip.
The ETRX2
communicates via its serial port, so the user’s firmware must use the UART of Serial Controller 1.
The nRTS and nCTS lines are connected to the USB bridge chip. The LED on the USB stick is
driven from ETRX2 pad I/O1, which is EM250 pin GPIO14.
In order to download custom firmware onto the ETRX2, the Ember bootloader can be used or
alternatively the ETRX2USB can be directly connected to the Ember InSight Adapter for
programming and real time debugging.
