Hello community,

If default Linux BSP image, it have H/W VPU library and enable VPU module clock and power,

on no-VPU device like MCIMX6Q4AVT08AER, what happen to run video encode/decode application

on this device?

On this device, it can call software video enc/dec library automatically?

Or to use no-VPU device, does it must need to use some special kernel

disabled VPU expressly?

No, you don´t need re-configured, Uboot detect which processor do you have, and the VPU is disable.

Hello Takayuhi,

In a device with no VPU, when running the BSP the VPU is disable and if you run a video it will mark an error.

Hello Bio_TICFSL

Thank you for your quick response.

I hope to know which level it must care for no-VPU device.

  1. It must need to use u-boot rebuild with disabled VPU configuraton.
  2. It must need to use Linux kernel rebuild with disabled VPU configuration.
  3. u-boot and Linux kernel can use with default setting, but if call vpu_init() library API, it will return an error.

Does it need a re-configuration for u-boot or Linux kernel?

Best regards,

Ishii.
