Hello,
I just built an image with SDK for the imx6 sabrelite. (ie: MACHINE ??=
'imx6qsabrelite')
Command: bitbake core-image-full-cmdline -c populate_sdk
I noticed that the SDK toolchain is based on "gnueabi" instead of
"gnueabihf".
Here is the list from the opt directory:
dev@dev-i3:/opt/poky/1.6+snapshot$ ls
environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi
site-config-cortexa9hf-vfp-neon-poky-linux-gnueabi
sysroots
version-cortexa9hf-vfp-neon-poky-linux-gnueabi
dev@dev-i3:/opt/poky/1.6+snapshot$
version-cortexa9hf-vfp-neon-poky-linux-gnueabi
I thought that the imx6 was a armhf device.
Why is the default toolchain using "gnueabi" and not "gnueabihf" for the
sabrelite target ?
Is there a way to change the SDK to use gnueabihf ?
In fact, I find it scary that the default toolchain is not armhf. What is
the reason behind that ?
Is it because of the video (GPU/VPU) driver ?
Thanks,
ssinfod

Does anyone have any input on this ?
Thanks

What makes you think it's not HF already? (hint - the hf is
part of the CPU model cortexa9hf)

You can try this test if you are unsure:
readelf -A /proc/self/exe
If the text "Tag_ABI_VFP_args" is present, then the system is using ARMHF. Otherwise it will be ARMEL.
