No singal at 2D_ACE CLK out PIN

[Makabaka]

Dears:

The customer configured the RCW file and enabled the DCU device tree according to the LS1021 LSDK and RM processes.

LS1021 starts normally, and the DCU module is enabled in the UBOOT log.However, the 2D-ACE_CLK_OUT signal of LS1021 cannot be detected.

What are the causes of this problem?
