we at SLS are planning a solution with Compact Flash cards and PMC CF (PMC234) adapters from RAMIX (or GE Fanuc Embedded Systems, http://www.geindustrial.com/cwc/gefanuc/embedded/) that plug on an IOC PMC slot. I could bring the system (mv5110) to boot from the CF, but unfortunately have too little time to get further than that. However, now the work is continued by another person and hopefully we will be running soon (although that person is also quite loaded with work.) To boot from CF one needs a few modifications to the vxWorks kernel; the bootrom also needs to be rebuilt. TrueFFS is not required (although I first thought so) because the CF card has a normal IDE interface. When one gets that to work, it looks actually rather nice; the CF looks like a normal disk where one can simply copy files. Booting is really quick. We plan also to use industrial grade CF cards (for example from SanDisk) which are guaranteed for 2 million write/erase cycles and have a 7-year guarantee. They are a bit more expensive than normal commercial versions, but the increased reliability should more than offset the costs.
