OK - I'll throw myself on the mercy of the community :-) I have installed hush in my u-boot.
I want to fix the following command sequence so that the board only boots if an image was actually loaded from the mmc card bootcmd="mmcinit ; ext2load mmc 0:1 0x10400000 /boot/uImage ; bootm 0x10400000" I've tried using && but that doesn't seem to work as expected... for instance if I use bootcmd="mmcinit && ext2load mmc 0:1 0x10400000 /boot/uImage && bootm 0x10400000" the sequence stops if the mmc isn't found, but always stops after the ext2load, even if it's successful. I have tried bootcmd="mmcinit ; mw 0x10400000 66 12345 ; ext2load mmc 0:1 0x10400000 /boot/uImage ; bootm 0x10400000" but the bootm still runs even if no card is inserted and I turn the power off for 1 second. So I'm missing something there!!! Can anyone help?
