Build BSP with crosstool-NG

I am trying to build the meta-fsl-bsp-release using a specific toolchain

I have installed (but not configured) crosstool-ng

I have 2 questions:

1) what do I configure ct-ng to be ?

arm-cortex_a8-linux-gnueabi

arm-unknown-linux-gnueabi

The built in cross compiler looks like cortexa9hf-vfp-neon-poky-linux-gnueabi

2) How do I tell Yocto to use my toolchain ?

Thanks

John

Hello John Laughton,

You didn’t mention which processor you are using and I haven’t personally tested it but I would go with arm-unknown-linux-gnueabi unless you are indeed seeking to build a toolchain for a CortexA8. The BSP supports the i.MX6 which is a CortexA9 processor and hence cortexa9hf-vfp-neon-poky-linux-gnueabi is used.

As for how to force Yocto to use an external toolchain, please see section 3.5 of the Yocto Project Application Developer’s Guide (link below)

I hope this information helps!
