This is the "Peach Pi" according to this[1] page. With the aid of the wiki page (and a lot of help from people on this mailing list) I was able to build an image. Differences, compared to wiki page: - r2669385 don't build for me, so I used r276666 - kernel config file: # kernel config file for Chromebook 2 Peach Pi include "CHROMEBOOK-PEACH-PIT" ident CHROMEBOOK-PEACH-PI #hints "CHROMEBOOK-PEACH-PIT.hints" options ROOTDEVNAME=\"ufs:/dev/da0p3\" Unfortunately, it won't boot, it just hangs after starting the kernel. I've tried this: (transcribed "peach #" is the U-Boot prompt) peach # usb dev 0 USB device 0: Device 0: Vendor: Kingston Rev: PMAP Prod: DataTraveler 2.0 Type: Removable Hard Disk Capacity: 7441.6 MB = 7.2 GB (15240576 x 512) ... is now current device peach # fatload usb 0:2 0x40f00000 kernel.bin reading kernel.bin 5459684 bytes read in 2953 ms (1.8 MiB/s) peach # go 0x40f00000 ## Starting application at 0x40F00000 ... (hangs here) and this: peach # usb dev 0 peach # fatload usb 0:2 0x20f00000 kernel.bin peach # go 0x20f00000 ## Starting application at 0x20F00000 ... (I didn't transcribe output from all commands) I think that 0x20f00000 is the correct address to use (based on the files included in the kernel config file), can anyone confirm this?
