Hopefully the experienced iMX6 = developer will chime in. Again, I am willing to pay for services and then s= hare the results with the community. > > 1. Would love to read your notes on Hummingboard. I am using Wandboard an= d Wandboard Dual for testing purposes and have been able to get FreeBSD bin= ary image (from the website) loaded and functioning albeit it's way too slo= w even for rudimentary tasks such as vi (on the Solo). I suspect 512MB is n= ot sufficient. Ultimately, I would like to be able to make a smaller image = ourselves but have been having a hell of a time with Crochet Give me a few days, I just got back from vacation and kids don't sleep well during summer hours so I have very limited time right now, but I will get you what I have so far. > 6. NAND flash/eMMC ... our main goal is that - at the minimum - the kerne= l should be on a flash chip of some sort so that boot up does NOT require a= n SD Card. Are you aware of any flash chip that can be used by uboot to boo= t FreeBSD? It's possible to run u-boot from NAND and then run ubldr/kernel from a different source. It may even be possible to manually load ubldr from NAND (or even manually load the kernel from NAND in u-boot) but you would need to find an alternative for the kernel and rootfs, especially if you want to update your kernel ever. Not what I would call desirable, but I have *heard* of production systems running like this. > 8. SATA ... may be an interesting option instead of using flash. The main= issue is that our products are price sensitive and using SATA adds at leas= t $10.00 to the BOM. As such - or unless I am mistaken on the price - SATA = is not a requirement for me Hmmm... at work we use an apacer solder on 2 GB chip that comes in considerably under $10 I believe. Not sure if a little 2GB chip is still available. http://us.apacer.com/products/SDC4-18-pin. Regardless, there is no support at this time. Russ
