i.MX 6D ERR009623

Hi,

I have a question about errata ERR009623 of i.MX 6D.

There two workarounds.

Either
- set Y stride line & UV stride to 16 bytes aligned when format is NI/PI 420/422 using SMFC
channel
or
- change the IDMAC burst size of the particular pixel formats from 32 pixels to 16 pixels

When it chose the first workaround, does Y stride line and UV stride mean the parameter of Stride Line SLY and SLUV in Table 37-14. Channel Parameters Memory for non-interleaved (continued) of i.MX6DQ reference manual?

Then, should these SLV and SLUV  align 16 bytes when format is NI/PI 420/422?

Best Regards,

Sugiyama

Hello,

   Your understanding of the Stride Line parameters is correct.

  Note, the erratum is actual for i.MX 6DualPlus / 6QuadPlus only.

Have a great day,
Yuri
