The "some scripting capabilities" includes a more or less complete bourne shell (the "hush" shell from busybox). Things like if/then/else/fi, for/do/done, while/do/done, until/do/done or operators like && and || are available. For a trivial example: to recover from corrupted images (bad checksum etc.) you could use setenv bootcmd 'bootm $addr_primary || bootm $addr_secondary' etc. Best regards, Wolfgang Denk -- Software Engineering: Embedded and Realtime Systems, Embedded Linux Phone: (+49)-8142-4596-87 Fax: (+49)-8142-4596-88 Email: wd at denx.de "A fractal is by definition a set for which the Hausdorff Besicovitch dimension strictly exceeds the topological dimension." - Mandelbrot, _The Fractal Geometry of Nature_ ** Sent via the linuxppc-embedded mail list.
