At some point soon, we would like to move the IXP1200 board from the passive PCI backplane to a traditional Pentium motherboard. I am starting this thread so that we can get a feel for the issues involved. It seems that there are several hurdles we must clear before doing this: 1. The PCI arbiter function must be disabled on the board. * Supported by J13 (CFN1) 2. The PCI reset function must be disabled on the board. * Supported by J14 (CFN0) 3. The board must be configured so that generates interrupts rather than receives them. * (Partially?) Supported by J10, J11, J17, and J9. 4. There must be a way to get the application code into the board. * One way would be to have the board boot up in a passive mode (selected by an unused combination of the GPIO[3:0] jumper settings) where the StrongARM waits for code to be written from the PCI bus by the host. On some signal from the host, the boot code would jump to a well-known address to run the downloaded code. Is this list complete? I know the engineers at Intel have been thinking about the problem because they wanted to do exactly this for the sessions at the Intel Developer Forum in Palm Springs. Thoughts? Ideas? Comments? -Scott
