Wilson @ 2010-02-05 16:25 UTC (permalink / raw) To: barebox I am curious if anybody has done any work on getting barebox running on the leopardboard, so I do not reproduce effort. I am especially interested in setting up a bootloader that directly supports USB and DFU, so that I do not need to use the UART/serial port.

I know nothing about the leopardboard, from googling I found out that this is a beagleboard with a camera connected to it, right? Barebox runs on the beagleboard, but unfortunately we do not have USB support for it. You would have to port the usb driver for it, then DFU should work. As a first shot you can compile the beagleboard defconfig and see how far you get.

The beagleboard uses an OMAP3x of course. Unfortunately, even I am confused on the TI naming scheme as to what is an OMAP versus what is a DaVinci. I will probably do as you suggest - start with the beagleboard configs and also look at the leopardboard code in the ti u-boot repo. Hopefully that will give me enough data to get the basic barebox running. The USB worries me, since I am just familiar enough with it to know how complex it can be. Time will tell. Thank you for your input.

Then I'm afraid you have to start porting from scratch. If you're lucky they share some peripherals. > > I will probably do as you suggest - start with the beagleboard configs > and also look at the leopardboard code in the ti u-boot repo. Hopefully > that will give me enough data to get the basic barebox running. Experience showed that it's a good way to start barebox from U-Boot as a second stage loader and add the low level init stuff later.This way you should be running up quite fast. Feel free to ask further questions about it. > > The USB worries me, since I am just familiar enough with it to know how > complex it can be. Time will tell What kind of controller does this SoC have, EHCI, OHCI?

It looks like MUSB with CPPI DMA, similar to what is in other Davinci chips. If so, there's a kernel driver for it in Linux (see drivers/usb/musb/) with support for the DMA engine as well. OMAP3 uses MUSB with its own "Inventra" DMA engine. - Anand _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox ^ permalink raw reply [flat|nested] 6+ messages in thread
