I'm currently working on integrating the Micro2440 stamp module onto a custom PCB board. One issue I'm running into is the lack of availability of the DM9000 Ethernet IC. Does anyone know where we can purchase smaller quantities of this part or a suitable replacement with Linux driver support? Best regards, Element
Utilizing micro2440 on custom board and DM9000 Ethernet
Take a look into the linux kernel: make menuconfig Device Drivers ---> Network device support ---> Ethernet (10 or 100Mbit) ---> Most of these devices you can use as a replacement.
Thanks for the tip. I notice that a lot of Ethernet chips are PCI bus based. I'm guessing the S3C2440 doesn't have PCI support directly. I think we may settle on the SMSC LAN9220, since it appears to be readily available, affordable, has a small chip footprint, uses a 16 bit bus (like the DM9000) and has Linux support. Element
Do not forget the bootloader. You also need to adapt it, if you want to use the network at this early boot stage.
