Dear Arno Steffen,
In message 804f0d21001140104o3543921cx2b4422fbc8a9e6b@mail.gmail.com you wrote:

In this way the second command will not be executed bootcmd=run boot_fs1; run boot_fs2
Right, this method can only detect when the boot command fails, for example because of corrupted images. It cannot handle situations where the kernel crashes, or where the application does not start up successfully. To handle such situations you have to use the bootcount feature, usually combined with a hardware watchdog which will reset your board in cases where it just hangs.
Bootcount is a great idea, but don't know right now how to do this. Also

will stress the flash, as it has to change the environment every time it boots.
No, this is wrong. Nothing neds to get written to flash when booting. The boot counter is NOT stored in the environment, but in some hardware register or other storage that is known not to change it's value during a reset.
Although I add hush to my config file #define CONFIG_HUSH_PARSER 1 /* use "hush" command parser */
and it compiles hush.c to hush.o I get
Unknown command 'if'
Can you please provide the full log, including all your input and all output? Please include the same (full input and output) for running this command:
=> echo foo || echo bar
Best regards,

Thanks for answer. My uboot is a 2008.10 (Mistral/TI EVM board)
OMAP3 # echo foo || echo bar foo || echo bar OMAP3 # setenv check 'if imi $addr; then echo Image OK; else echo Image corrupted!!; fi' OMAP3 # run check Unknown command 'if' - try 'help' Unknown command 'then' - try 'help' Unknown command 'else' - try 'help' Unknown command 'fi' - try 'help' OMAP3 #
The line:
#define CONFIG_HUSH_PARSER 1 /* use "hush" command parser */ I put into /include/configs/omap3_evm.h
