Paul, Our protocol is as follows: SPI clk = 307 kHz, DELAY = 22 uSec, Msg Interval = 10 msec, Msg Duration <= 5 msec, Each slave recognizes 1 or more of NMSG unique message IDs. Main connected on a common SPI bus with 1 - N slaves Each slave disables its SOMI line until it recognizes an assigned mes...

We use MCS12 microcontrollers in a distributed system using an SPI bus for a message passing backplane. We may want to replace one or more of these microcontrollers with Netburner modules in the future. It would also be useful if we could simulate some of the slave SPI messages using a Netburner mod...

Previous coldfire products (5272) did not have the capability to operate as an SPI slave device. Does the DSPI module of the 54415 allow operation as an SPI slave?

Thanks,

Is NNDK 2.6.9 available for download? I see the release notes for it, but I can only find a link for the 2.6.7 download.

I have been experiencing similar problems with TCP. The Netburner (MOD-54415) connects as a client to a local TCP server (currently simulated by a PC). I experience a problem when the PC is connected but not running the simulation program (TCP Server). In this instance, the Netburner attempts to Con...

Is the Coldfire 54415 real-time clock peripheral able to be used on the MOD54415? It looks like the backup battery pin (CPU Pin E16, VSTBY) is available on the Netburner MOD54415 header as pin 3. Just wondering if its possible to use this peripheral? Are there any examples? Has anyone tried it? Than...

Problem Solved! Thanks for the suggestions. I had inserted a network hub in series between the Netburner module and the switch of the vehicle network to verify that the fragmented packets were reaching the Netburner. The suggestion that the packets were being dropped by the Netburner proved correct!...

I am developing an application using Netburner Mod-5272s for a private vehicle network. The network uses a custom message protocol built on UDP protocol. During initial connection with the Network (and subsequent vehicle configuration changes) a custom server provides DHCP info and a vehicle directo...

Thanks Larry!
The updated Etherlink() function works exactly
like I need it to now.

Netburner support is awesome!

How can I detect a failed network connection quickly? I have been using the EtherLink() function to check the link status on a Mod-5272, but it seems to take several seconds to indicate a link failure after unplugging the cable. I would like to detect a failed link after 100 or 200 msec. Is there an...
