Hi, all:

I found the imx6d ipu base address is 0x2600000 in RM., but in the device tree is 0x24000000. Why is this?

Hello,

the following thread clarifies the issue :

Writing to the IPU's CPMEM region

"For iMX6, IPU registers start from 0x02600000, and CPMEM is at 0x02700000.

The code defined "REGS_IPU1_BASE (0x02400000)" is based on old document, but when

access registers, it will always add offset 0x00200000. In new document, the IPU1 address had

been changed to 0x02600000. Software haven't update to this base address, there is no function

impact, because the software will always use 0x02400000 + 0x00200000 to access IPU registers."

Have a great day,
Yuri
