[U-Boot] return value from do_ext2load
the do_ext2load procedure returns the file length if it succeeds... which means you can't do
#define CONFIG_BOOTCOMMAND "mmcinit && ext2load mmc 0:1 0x10400000 /boot/uImage && bootm 0x10400000"
Is this part of some vast eternal plan and/or can anyone see a way to make it function as desired anyway?

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?

Which exact version (commit ID) are you running?
And which platform / board is this?
Best regards,

I'm running a home-brew based on 2008-10
I started with NGW100 version, and went on from there :-(

You make a pretty definitive statement here. What makes you so sure?
Let me tell you that you are wrong.

It is working perfectly fine for me.
Of course I don't use old, buggy code as you seem to be doing.
My code contains this commit:
commit 4b7511478b62a539e5b066d19a986b75e5d9a527 Author: Wolfgang Denk wd@denx.de Date: Tue Jul 28 22:07:37 2009 +0200
Fix ext2load return code
Make the ext2load command return 0 on success (instead of the file length). ...

Well that would improve things :-)
I'm only using old code because when I last worked on u-boot the latest code couldn't write the AVR32 flash, so I had to back up to the most recent one that could.
I don't have time today to do a complete update, but I'll try applying that patch in isolation.
Thank you.
