Jonathan, All,

Solid-Run HummingBoard i2eX defconfig and bootable microSD Bash script

We have started to use genimage to generate images without requiring to be root.

See for example how it is done for the Raspberry Pi:
board/raspberrypi/

Otherwise, your script is really complex just to create two aprtitions and put a bumch of files on the first and extract the rootfs on the econd. genimage does that quite nicely.

The only "drawback" top genimage is that the generated image is just the size required to put the rootfs. Not much additional space is available, and you'll have to resize the FS afterwards (either on firt run or manually after dumping the image on the device).

Would you care to have a look at using genimage instead?

I'm marking this patch as "changes requested" in the patchwork.

Thanks!

Regards,
Yann E. MORIN.

+	"output" is the Buildroot output directory, in this case for an in-tree build
+	"HummingBoard-i2eX" is the board model
+	256 is the size of the rootfs partition in MiB (default 128 MiB)
+
+See also the USAGE variable in the make_sd_card.sh.
