CCR1072 microSD howto?

Hi
feeling a bit dumb, but has anyone ever managed to use a microSD in the ccr1072?

we seem to be unable to solve this riddle.

and while we are at it any tested smartcards for the smart card slot?

thx

Hi,

does anyone has an answer how to use a micro SD card in RouterOS to boot the system, too?
We are running a CCR1072 and realized, it has only 128MByte to store the operating system. But with two partitions this is too less for RouterOS 7.5…
