Cover letter [U-Boot] [PATCH 0/3] avr32 fixes

Ok, I wasn't aware of that problem. I don't think I've ever tried running u-boot with empty environment; in fact, I'm not even sure how you do that since it will fall back to a default environment if it can't find anything in flash.

Yes, the strange thing is that it worked fine a few times. But for some reason, it failed later on.
I'll try to reproduce the problem and make a proper report.

Here it is, pasted as quotation to avoid line wrapping:

I don't know how u-boot knows the flash layout. Maybe something changed between 1.3.3 and 2008.10 (default partition table?)

I compiled pristine 2008.10 for atngw100 with just LZMA compression enabled and the right command line and boot command for OpenWRT:

This is what 1.3.3 does. I just took the plain image from OpenWRT and not the one padded to 128K bytes as usual with OpenWRT. For 1.3.3, that does not seem to make a difference.

OpenWRT only adds LZMA decompression support to the pristine sources.

You notice that the flash size is correctly recognized. I fully erased the flash between both attempts and there was no power cycle in between. Actually, I'm not even physically touching the board.
