Obviously this must be balanced with the space needed, but you then get to choose a processor that fits your needs, and you get a much more flexible system (doubling the memory would cost almost nothing, for example, and a development version with enough ram for all the code would be very useful).
From: chris on 18 Dec 2006 19:12 Hello all, I work for a company called NetBurner. NetBurner has a $99 MCF5270 based development kit. It includes a NetBurner Mod5270 Core Module and development board, Eclipse IDE, uC/OS RTOS, TCP/IP stack, web server, C/C++ compiler and linker, flash file system and deployment tools. The NetBurner Mod5270 module that comes with the kit has 10/100 Ethernet, 47 digital I/O, 3 UARTs, I2C, SPI, four channel DMA, and 16-bit external data bus. The module has an integrated 32-bit 147MHz Freescale ColdFire processor with 512k flash memory, 2MB external SDRAM, four 32-bit timers, watchdog, chip selects, interrupts, and four programmable interrupt timers. It includes NetBurner's Eclipse IDE so you can write code in ANSI C/C++ within the Eclipse environment, and compile and load it into a NetBurner core module over a network. It also comes with a program called AutoUpdate. Its a tool that is used to download a new code image to a NetBurner device. This update can be done from any point that has network access. Also, the source code is included with the kit so you can make your own customizations for your own application. NetBurner has some videos so you can see it up and running here: http://www.netburner.com/embedded_eclipse.html Here are links to their network development kit page, and their online store: http://www.netburner.com/products/development_kits/network_development.html http://www.netburnerstore.com/embedded_ethernet_development_p/nndk-mod5270lc-kit.htm If you still need more flash, NetBurner has the MOD5234, MOD5272 kit with 2MB of flash, 8MB of ram.

Hey Martin, You can join the NetBurner community here: http://tech.groups.yahoo.com/group/netburner_group/ Also note that the SB70 serial to Ethernet dev. kit is $99 and comes with 3 months of technical support direct from NetBurner. I used the kit to update the SB70 with a custom webpage and filtered incoming serial data before re-transmitting over the network. You can do all of the typical serial to Ethernet setup through the webpage (no programming), but its a pretty simple process to update the HTML using the included NetBurner Eclipse IDE. Anyway, you can find more details here: http://www.netburner.com/products/development_kits/serial_to_ethernet_development.html Chris martin griffith wrote: > On 18 Dec 2006 16:12:04 -0800, in comp.arch.embedded "chris" > <curibe(a)netburner.com> wrote: > > >Hello all, > > > >I work for a company called NetBurner. > > > >with 2MB of flash, 8MB of ram. > > > >Here is their product page: > >http://www.netburner.com/products.html > > > >Chris > At bit OT, but I was looking at the SB70 serial to ethernet, so I > tried to register to have a look at the forums, but it did not like me > as I dont have a product or serial number to log in with > > > > > martin |
