Hi,
We have been using QNX 2 … QNX 4.25 for x86 based embedded systems
manufactured by us. We have also utilised the same for a number of networked
compters running applications developed using Photon microGUI.
Currently we have several requirements for which we need to
design/develop embedded systems (not x86 based, preferably microcontroller
based). We do not have any exposure of using QNX on platforms other than
x86. Due to our familiarity/experience of QNX RTOS, we intetnd to select a
platform which is supported by QNX Neutrino. We require features like
embedded file system, serial I/O, support for ethernet network, TCP/IP, USB
for the same.
Kindly comment on how this evaluation/selection process should progress.
…
Which all options do we have? (preferably microcontroller based)
Which is the best option (technically and commercially) available to
start off with development of a prototype?
Regards,
Krupa
Hi,
any “microcontroller” version of one of the families supported by QNX6
(PowerPC, ARM, MIPS) I know doesn’t have a MMU, so you’ll have to choose an
embedded CPU with external memory. If I look at your requirements, I would
suggest you three devices:
-
Motorola MGT5100
(http://e-www.motorola.com/webapp/sps/site/prod_summary.jsp?code=MGT5100&nod
eId=03M943030450467M98648)
It’ll cost you about 28$ (10,000+).
This device has everything you need but seems rather complex (and may
take some time before all bugs are fixed)
-
IBM PowerPG 405GP
(http://www-3.ibm.com/chips/techlib/techlib.nsf/products/PowerPC_405GP_Embed
ded_Processor)
It’ll cost you about 32$ (10,000+).
This device has everything except USB but you can easily add this via
PCI or local bus (a USB chip will cost you about 3-9$).

Alchemy Au1100 (MIPS based, Alchemy was bought by AMD last month)
