I can send "UYVY" data with "eppi" module. Data bus 16bit (for Y 8bit, for U/V 8bit)
The conversion of video data "YUV422 planar" and "UYVY" takes too long.
I tried to send the YUV422 planar data using the "split" function. But I was not successful.
* Can I directly send the "YUV422 planar" video data with blackfin?
* Can you share sample setting about this work?
I'm not having trouble using data submission or split mode. But I couldn't make the right settings for 2D DMA.
"DMA15" does not work correctly in 2D.
Is there any detailed document or sample for DMA?I've reviewed the hardware guide.I can't get the result I want when I apply the information there.
I sent the YUV422 planar image to the EPPI module.
I used 2 DMAs(DMA14 and DMA15 for ADSP-BF707) and I configured the second DMA in 2D.
DMA14 is sending Y data.The DMA15 sends the U / V sequentially.
In the EPPI module, you get the data as UYVY (YUV422).
I hope that will be useful.
