There are a few new shell functions not yet documented in the VCRT 5.0 documentation. These are usualy mentioned in the chg2.log - see separate articles on VCRT OS updates.

However - here we want to list and explain these new fuctions in more detail. This list may not be complete yet, but will be extended over time:

kl - kernel log - this function displays a range of SD card information, like: size, number of sectors, manufacturing ID, etc. If yuo ever face trouble with a particular card, please send us the "kl" printout.

fmt - formatting the SD card where applicable. New are the use of different parameters:     - used without any parameters -> the card will be formatted to its actual size with 900 to 1000 cluster. 

different options:

-  no parameter: -> he card will be formatted to its actual size using 900 to 1000 cluster

- 1 parameter smaller 32k: -> the card will be formatted to that number in MB

- 1 parameter greater than 32 k: -> card will be formatted with that number of sectors

- 2 parameters: "fmt a b" - > with a > 32 k and b the clustersize in "number of sectors", allows setting of cluster size. Larger Cluster can speed up access, but limit storage for smaller files (default is 900 to 1000 Cluster / SD card, which makes different cluster sizes depending on the actual SD card size for maximum performance).
