about memory copy using iMX53 IPU

Hi everyone,

Please tell me about memory copy using iMX53 IPU. I copied data from Buffer1 to Buffer2 using CH 11 and CH 22 (Post processing). But, I would like to copy memory using PreProcessing VeiwFider. I also want to resize.

Is it possible to copy the buffer using PreProcessing ViewFinder? If possible, Can it be realized by using the CH12 and 21? I am experimenting with various settings, but I can not copy it. Please tell me what kind of register should be set.

By the way, when using CH11, CH22 (PostProcessing), I was setting the following registers.

 

IPU_IC_IDMAC_1
IPU_IC_IDMAC_2
IPU_IC_IDMAC_3
IPU_IC_PP_RSC
IPU_IC_CONF
IPU_IDMAC_CH_EN_1
IPU_CONF
IPU_INT_CTRL_1
IPU_CH_BUF0_RDY0

 

CPMEM
