Main differences are that mine only has 1 SATA port wired off of the ASMedia 1061 instead of 2 and has an extra PCIe slot with only USB wired to it for 3G modem support and a SIM card slot to go with it. It also has 512MB RAM and 16MB SPI flash. Hi Stanislav, Got the WiTi board here... I haven't tried in the expectation that you were going to make a version that runs in 256Mb. But If you'de like me to try the 512 version as well.

It expects to find a filesystem on ada0, attached to ASMedia 1061 on the pci bus (in case your boards have SATA ports). So if you don’t have SATA you won’t have a filesystem, but at least we’ll know whether it boots on your boards or not. >>>> >>>> Please let me know if it boots on your boards. >>>> >>>> Best wishes, >>>> Stanislav >>>> >>>>> On Dec 11, 2015, at 18:40, Stanislav Galabov <sgalabov@gmail.com> wrote: >>>>> >>>>> Now this is something I was hoping for :-) >>>>> >>>>> I’ll tidy things up next week and I’ll send the initial dirty patches over to you only (for now) if it’s ok with you? >>>>> I’ve hacked on top of the rt305x support that’s in the tree for now, but in a mt762x directory and there are still a lot of leftovers from rt305x, but at least the thing boots and goes multiuser albeit on a single core right now :-) >>>>> >>>>> Please let me know if this works for you. >>>>> >>>>> Best wishes, >>>>> Stanislav >>>>> >>>>>> On Dec 11, 2015, at 18:36, Adrian Chadd <adrian.chadd@gmail.com> wrote: >>>>>> >>>>>> hi, >>>>>> >>>>>> holy hell yes. >>>>>> >>>>>> Can you please put all of your patches up online?
