My info is infinite reads but limited writes this means that you must use a journaling file system or build in track remapping

Hey guys. I posted awhile back when having some functionality issues with a TS-7200 and realized the 7553 was really the platform I should have been working with from the get-go.

Sweet little box this 7553. I've gotten all my software ported over and it's working perfect. After only a couple weeks with it, I think I'm ready for deployment.

We'll be preparing quite a few of these little guys. Having the ability to insert a pre-imaged MicroSD, set one jumper, and run one command (rm linuxrc; ln -sf /linuxrc-sdroot /linuxrc; save) to change the boot is very attractive in terms of quick deployment, and easy field upgrade (send customer a new MicroSD card, done!).

One question I had was in regard to the longevity of these little MicroSD cards, and their resilience to repeated power loss.

Customers will not have the ability to shutdown nicely, power will always be removed to turn off. I based my image from the latest.dd image available from the Technologic website, which if I remember correctly is formatted ext3.

Has anyone had any experience with a similar setup? How are the boxes holding up, and have the MicroSD cards been lasting?

I've been also pondering making use of the xnand drive with a custom busybox that includes the compiled apps i need and just script the flashing process to ease prep/deployment. I know bootup time would be significantly better than my current 1 minute timeframe, and resilience would be better. Downside would be that I lose the ability to do remote software updates. Anyway, I have yet to break ground on that idea, or even wrap my brain around how that's done.

Thanks!
Dan
