Hi, all. Recently I downloaded the latest version of FlashMagic tool (version 5.74.2160) with secondary Ethernet bootloader example for LPC2300 included. The provided example of bootloader code is for LPC2364 and the example application (Blinky) is for LPC2378. My custom board is based on LPC2368 and my final intention is to allow in-field firmware upgrade using Ethernet link, when the seco...

high bandwitch ethernet communication

Hello, In our application we have to receive and merge several proprietary serial channels (200 MHz) over fibers, and send all the data over Gigabit Ethernet. The bandwidth is ~60 MByte/s, sustained. While generally sending this amount of data is possible over Gbit Ethernet, doing so in an embedded system isn't easy. That's because we need to send it by UDP or TCP, for which a TCP/UDP/IP...

Greetings: (sorry for the cross post if not appropriate: similar queries were cross posted to these two groups) I would appreciate info on the behavior of USB ethernet adapters which support 100 Mb/s ethernet when used on USB 1.1 hosts; manufacturers descriptions are lacking in specifics. Some essential questions: 1. Will these adapters negotiate 100 Mb/s when used on USB 1.1?

Hello everybody, can somebody suggest me a embedded linux module with RS232 and Ethernet interfaces? Not much more is needed. The RS232 interace is used to attach a GPRS modem module. I want to use one of the following configurations: 1 - FTP server for the ethernet side, upload then via GPRS to another FTP server or: 2 - daemon that loads a FTP file from the ethernet side a...

Hello all. Currently an engineering student. For my project I need to develop an ethernet interface between a control computer and some sensors and actuators. So I am planning to develop the following boards: 1. A board which I/O to connect 2 limit switches 2. Driver for small stepper motors Both these boards need to have a ethernet interface to be able to communicate with the control c...

I'v to use a TMS470 processor in my application which has to support 2 gigabit ethernet ports. As the TMS470 doesnt have a PCI bus, i have to use a NON-PCI gigabit ethernet controller (PM8336- only MAC+RTL8212N PHY). Is there any simple solution than this. Any suggestions most welcome!!!!!!!!!!!!!!!!!! Please reply asap regards, scooby

Hi, I'm looking for a cheap embedded ethernet controller board with 2 or more interfaces (10/100 Mbit), it should be programmable in C. Ie. what I'm trying to get or build is a device like a cheap router or switch that I want to program myself for analysing ethernet traffic etc. Any pointers welcome.

Hi, I've managed to buy a few Orange PI PC boards for very nice price, to be used as controllers for simple measurement and control system. I have created the Linux image using the newest Buildroot 2016.11 The board booted correctly, but I have found a very strange thing. Even though U-Boot supported Ethernet (also DHCP and TFTP), the Linux kernel didn't see the Ethernet interface. I've...

Hi Folks - I'm looking at a quick project that needs: - 16-bit AD data acquisition, - Ethernet connectivity - modest processing requirements (32-bits best) - ideally contemporary ARM supported by lots of toolchains RTOS etc. I'd love to use Actual Fusion (but only 12 bits) or Cypress PSoC (but no Ethernet). Quick look around shows lots of 12-bit solutions. Tern has high res AD but old x...

Auto uplink swaps the tx and rx lines of an ethernet port so you don't need crossover cables. How does an ethernet auto uplink port work? Is it covered by any standard? I have a device that doesn't work and I suspect auto uplink is interfering with it. Alan Nishioka alann@accom.com

Hi everybody, I am trying to make a ethernet terminal I/O board. Basically making an x86 based 1U solution. I am trying to route the onboard ethernet connection via a patch cable (Cat6). this works but I also want the link/status leds. I did a simple PCB with two modular 8P8C Jacks with LEDs and have connected them back-to-back. The inside Jack connects to my mobo with a patch cable and the ...

Low cost USB / Ethernet?

I am starting a new high-volume (10K umits per day) low cost/performance (a 10 cent 4-bit microcontroller will do the job) project, but this one has a twist; I have a requirement to make a USB version and a 10BaseT or 100BaseT Ethernet version. Just in case anyone has already done the research, does anyone here have a favorite chip for low-cost USB? For low-cost Ethernet? I have lots of b...

Hello, I am starting an investigation to determine the easiest migration path to move an existing product from 10 Base-T ethernet to 100 Base-T ethernet. The current product is a small embedded system running Linux (2.4.9 kernel) on a StrongArm processor, using the CrystalLAN CS8900A chip for the MAC/PHY. This chip is in a 100-pin QFP package. I'd love to hear that there is a drop in rep...

Hello.. well my on going project to write a TCP/IP stack on a pic is still "on going" and with the holodays here I'm going to get a good chunk of it out of the way. I'm still using slip to connect it to my PC, but recently I'v come to realize how much simpler life would be if I used 10baseT Ethernet. Basicaly because the chips that deal with this have more memory for packets then the ...
