i.MX8MMini build for Cortex-A53 (enable FPU & NEON)

[vincentz63]

Hello,

The i.MX Yocto Project User's Guide, Rev. L4.19.35_1.1.0, 11/2019 document states:

"All packages which are released as binary are built with hardware floating point enabled as specified by the DEFAULTTUNE defined in each machine configuration file."

This variable is defined in meta-fsl-bsp-release/imx/meta-bsp/conf/machine./include/imx-base.inc.

For the i.MX8, this is aarch64, so the BSP builds for a vanilla aarch64 architecture and not the Cortex-A53.

Could you let me know how to target the Cortex-A53 and enable NEON please?

Thanks

JP

Hello JP Arnaud,

Please apply modifications in the attached file to target the Cortex-A53 ((neon is enabled by defualt)). I can build imx-image-full with  these modifcations.
