I finally managed to make this comparison. I did this by taking my Poky/Yocto<br>
built system for a i.MX6 system (ARM Cortex-A9) and replaced the rootfs with<br>
one for the Gumstix Overo (linaro). The results were nothing like yours, so<br>
it's a bit confusing.<br>
<br>
I actually built an entire Linux kernel - not just the one directory you mentioned.<br>
<br>
Poky/Yocto - 37 minutes<br>
Linaro - 48 minutes<br>
<br>
There is some flex in these numbers as they were on different [brand] SD cards, etc,<br>
but I sure did not see the "5 minutes for Linaro vs 24 hours on Yocto" that you reported.<br>
<br>
Perhaps the only thing I did differently was I added the SDK tools to my Yocto system<br>
using these meta-packages instead of the list you used.<br>
packagegroup-core-sdk packagegroup-core-standalone-sdk-target<br>
<br>
You might try that to see if it makes any difference.<br>
<br>
n.b. part of what took me so long to get these results is I was trying to run this test<br>
on something closer to your Overo board. I have an older OMAP DM3730 board here that I<br>
tried to do these same steps, but it was unstable and I could not get the Linaro based<br>
file system to work at all. Very strange. In any case, I think the comparison I did get<br>
with the i.MX6 is valid.<br>
