Hi Fei Chen,
but I didn't find any document telling me what kind of linux can be used on ixp1200, how to run strongArm and microengine code on the ethernet evaluation board. Can anyone help me with this?
Vera does not use a RTOS such as Bluecat Linux. It uses a mini-kernel that acts as a bridge between an external processor such as a Pentium and the micoengines, similar to something described in section 2.7.1 in Intel Hardware Reference Manual, Dec 2001, Page 31. There is a need to erase the Intel firmware first before using Vera. StrongARM and Microengine codes are compiled into Motorola Hex Format files on Pentium and are then downloaded via the PCI bus onto IXP1200. Princeton also provide the necessary toolchains to compile StrongARM and microengine codes so there is no need to use the Developer Workbench to download the microengine codes as Micro Object files onto IXP1200. regards, cheewei
