Here's a resource to consider with Arm core you choose before purchase: http://www.arm.com/linux/linux_download.html and another: http://www.embeddedarm.com/linux/ARM.htm and another: http://opensrc.sec.samsung.com/ Research the linux port, conditions, kernel version, and whether or not you need embedded Debian, and what the details of the 'linux distro' are before you make a choice. Also consider what you'll use for an 'IDE" or integrated development environment. If you are developing a commercially viable product, nothing replaces a JTAG interface. If you are just noodling, then 'burn and churn' is ok. This also depends on how deeply you want to optimize/reduce the kernel and if you'll be needing RT, real-time, extensions or any other low level modifications, such as bootloader, eeprom for flash memory on the board. If you need 'hard real-time' or 'deterministic/state-machine' behavior, then research what rtos/kernel options and tools the vendor has with the linux 'port' and tools they support. Ultimate you may move some of their code over to something like embedded-Debian, or just study in under another RTOS before implementing a 'knock_off' under some flavor of embedded linux. Sure you can wing all of this on your own, but, it never hurts to ask the vendor what they offer, particularly in the area of hardware and sourcecode to drivers. Also, make sure the dev-board has the hardware you need, SD, Compact flash, mini-pci, pci, pcmcia, Ethernet, serial bluetooth, AD/DA etc, etc.... low power constraints, one of the chief reasons to use arm ,really affects the processor selection too. Personally, I'd like to hear back what you purchase, what you are basically trying to accomplish and why you chose the dev-board that best fills your needs and desires.
