Hi, I wonder which board did you win to get ? :) Also, Is your board able to boot into Snappy successfully ? If yes, I think the partitions of image should be fine to work well.
Before flashing image to SD card, you also can use `fdisk -lu /path/to/image` to check all the partitions. In my experiences of Snappy porting, I met a problem to break up the partitions generated by u-d-f, and I diff the hex between BSP image and Snappy. I found that u-d-f overwrote wrong the partition table due to bigger size of preloader binary, so I made the binary divide into two parts. Furthermore, The offsets also needed to be described in package.yaml in the OEM snap. The another interesting thing is that I need to make boot flag of 1st partition turn off, and then the board can boot to Snappy normally. XD This is my reflection, hope it can help you :) Cheers, Woodrow On Fri, Nov 20, 2015 at 1:15 AM, Andrea Bernabei < [email protected]> wrote: > Hello everyone, > > I recently won a dev board at a conference, and I'm trying to port Snappy > to it as a spare time pet project (yeah, this is the kind of things I am > into :D) > > I read the porting guide > https://developer.ubuntu.com/en/snappy/guides/porting/ > > and Ogra's post at > > https://ograblog.wordpress.com/2015/01/25/porting-ubuntu-snappy-to-a-yet-unsupported-armhf-board/ > > I have already patched the kernel with the required apparmor patches and > also uboot to add ext4 commands, and I successfully installed them on the > board. > > The problem I have at the moment is that the partition tablet of the image > created by ubuntu-device-flash (using my custom device tarball as input) > does not seem to be properly supported by uboot (and even some tools like > gparted). > > Here's what a few tools report when listing the partitions on the *sdcard* > (I tried both with a 32Gb and a 4Gb sdcard) > - uboot's "mmc part" reports just 1 partition, type 0c > - gparted only shows 1 big partition, like uboot, with unknown filesystem > and lba flag > - parted shows 4 partitions > - kpartx shows 4 partitions > > Any advice? > > Andrea > > -- > snappy-devel mailing list > [email protected] > Modify settings or unsubscribe at: > https://lists.ubuntu.com/mailman/listinfo/snappy-devel > > -- snappy-devel mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/snappy-devel
