i.MX6SDL VPU decoding result is "0" when decodes small data.

[satoshishimoda]

Hi all,

We need solution to the problem in VPU-driver.

When we decode a small data such as 16x16, response status from the VPU is becomes a complete.

But size of result is returned "0" occasionally in response status by VPU.

Hi all,

I found a solution.

This issue was occurred when wait a interrupt by vpu_WaitForInt function after start decoding, no interrupt was generated after decoding.

But wait a interrupt by polling and checking status with vpu_IsBusy function, it was avoidable.

Would you let me know this solution is reasonable?

Please give me a comment if there is better solution?
