I purchased a ConnectCore 6 SBC few weeks ago. I used the Yocto project provided with it, build first image, flash my target, and worked properly on it since then.
But the other day I tried to make a more "complete" yocto-image for my need, adding few (like 2 or 3) packages. But my rootfs image is now greater than 1 Gb... So U-Boot can not copy it to the sdram (which is 1Gb).
I've done my homework, and found out that there were possibility to ask for U-Boot to load the images directly to the flash, via tftp, with the "On-the-fly" mode => https://www.digi.com/support/forum/45191/there-size-limit-the-files-transfer-with-update-command-tftp
Yep... Well doesn't seems to work. Because at the end, I still have: "Writing chunk...[Error]: length of data exceeds partition size"
Then I fount another way to ask U-Boot to provide that: https://forms.na1.netsuite.com/app/site/hosting/scriptlet.nl?script=457&deploy=2&compid=818164&h=5928a16f2b6f9582b799&article=how-do-i-program-my-linux-images-onto-a-digi-embedded-module
Awesome ! But the function flpart doesn't exist with my U-Boot version... Great...
So, if anyone as an idea or just even a lead of what to do, that would be awesome !
Btw, my actual U-Boot version (for which I can not even find a complete doc): U-Boot dub-2015.04-r9.2+g0a4ec9f
Thanks a lot !
