Please tell me about memory copy using iMX53 IPU.
I was able to copy data from BUF 1 to BUF 2 in a way to use the IC.
I would like to copy data from BUF 1 to BUF 2 without using IC.
I found the following functions in the reference manual.
MEM -> VDIC --> MEM
input: IDMAC_CH_25, IDMAC_CH_26
I made the following settings to use VDI.
The thing that I want to do is a copy from BUF 1 to BUF 2, but the second input is necessary, so the same data is set in CH 25 and CH 26.
Results I tried
Interrupts of CH25 and CH26 are generated when one of the following bits is set.
But CH5 interrupt does not occur.
Please tell me how to copy memory using VDI without using IC.
refer to the Reference Manual of mx53,
• Input for combining: two progressive video/graphics planes
• Source: system memory
• Plane size: up to 1920x1200 pixels.
• Pixel format: RGB/YUV 4:2:2, 8 bits/value
but I found that you set it to 4:2:0, pls try to use yuv 4:2:2.
Thank you for your reply.
Please teach me.
Which setting should I change?
If it is CPMEM, I tried changing CPMEM's W1 [88: 85] (Pixel Format Select) non-interleaved 4:2:2
or partial interleaved 4:2:2, but no interrupt occurred.
