Hi Joan Xie, Thanks for the response. We are using VPU Lib 5,4,28 and firmware is 3.1.1. Can you please support us with latest release files/ptah as we could not get it from nxp site?
if you just want to upgrade the vpu besides of yocto bsp, one can replace the /usr/lib/libvpu.so.4 and /lib/firmware/vpu/vpu_firmware_imx6q.bin from the latest release.
