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.

This problem can be solved using solid state disks (or micro SD) they are very fast read/write, but are very expensive.

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.

For this you must use batteries as Jim says.

I'm starting with a ts7552 and have had problems with a Huawei modem, but I hope to fix soon.

regards,
