IMX6Q VPU API issue, vpu_Init() not working

Saad_Khan — Fri, 21 May 2021 04:51:55 GMT

Hello everyone,

I am trying to encode a video frame using IMX6Q VPU API's. This api "vpu_Init (NULL)" present in "#include <vpu_lib.h>" is getting stuck. I mean the control is not coming out of this api with status return.

I am using below BSP,

kernel - 3.14.52

buildroot version - 2019.02.8

Please let me know, what could be the possible reasons for this api not to work..

Hi Mohammed

one can try nxp release

https://source.codeaurora.org/external/imx/linux-imx/tree/?h=imx_3.14.52_1.1.0_ga

for vpu_Init() testing use unit test ../mxc_vpu_test/enc.c
