I've nothing better to do at that time.. ;) At that time i've no 48v PS and at same time i was looking for something to replace my server/router (which was suffering a lot with the very frequent power outages). So i've designed a power supply that work directly from 12v batteries and gives me some information about its state thru i2c. http://loos.no-ip.org:280/routerstation/images/13.html (basically - a little bit old, already added a charger for battery). http://loos.no-ip.org:280/routerstation/images/12.html (here the output is connected to my rspro and the i2c is connected on my routerstation - development time). >>>> All installed ports: http://pastebin.com/yHcszFpR >>>> >>>> It's running fully static, booting a gziped kernel from onboard flash >>>> and with a full system on a 8GB SD card (i've another two 4GB >>>> memsticks, one is used for ports and the other for sources and obj). >>> >>> Again, it would be great if you could share your experience - I would >>> like to run from flash too, but did not came there yet, I am still only >>> at netboot stage with USB flasdisk based file system. >>> >>> Regards, >>> Milan >> >> adrian@ keeps a wiki page with some information about this: >> http://wiki.freebsd.org/AdrianChadd/UbiquityRouterstationPro >> >> I'll poke him about a port for this flash tool, it's very simple to use. >> > > Is it possible to read/write flash from FreeBSD itself?

Be aware that currently we've a bug with geom_readboot and geom_label, they won't work together (it was given to me a patch that should fix this, but i did not managed to test it yet). Try it with bs=64k and it should work (as Monthadar said, adrian@ have some patches floating around that reduce the block size to 4k iirc). I'll try to post my script and Makefile for the mkfwimage.c (here is a sample with the ouput of routerstation for the flashing procedure: http://loos.no-ip.org:280/routerstation/) > Also, there is a pin header marked UART, just opposite to RS232 connector.

(unfortunately) It's better look at some usb->uart cable (like ftdi, prolific, etc.) or some other gpio solution. Regards, Luizhome | help
