Recently I want to save the state of the DP in IPU, but I found that the registers of DP have no physical address. DP only loads the parameters from the shadow register memory according to the type of the flow (sync, async0, async1). Can the registers being used by DP be accessed?
Hi He
please look at
sect.37.4.9.1 "The DP programming model",
sect.37.5.108 "DP Common Configuration Sync Flow Register" and further on text
IMX6DQRM i.MX 6Dual/6Quad Applications Processor Reference Manual

Thank you very much, I found the corresponding chapter in IMX6DQRM. Do you know what the situation is about imx53? In imx6, the DP has its own registers listed start from sect.37.5.108, but the registers in imx53 are only in the shadow register memory, not in the DP module. Do you know the base address of the registers in the DP module?
Hi He
for i.MX53 :
sect.45.51.374 "DP Common Configuration Sync Flow Register
(IPU_DP_COM_CONF_SYNC)" and further on text
i.MX53 Reference Manual (rev.2.1 6/2012)
