Tool/software:
Hi，
TDA2ex VSDK3.05
DRAM: 1 GiB
uboot laod load dra7-ipu2-fw.lzop, dtb, zImage， mount rootfs.
I did it according to the following method.
1.uboot load dra7-ipu2-fw.lzop
Other nuclei are not needed, I have shut them down.
2. When opening in DTS
LATE_ATTACH(ipu2);
LATE_ATTACH(timer3);
LATE_ATTACH(timer4);
LATE_ATTACH(timer9);
LATE_ATTACH(mmu_ipu2);
The kernel starts abnormally.
If you don't open LATE_ATTACH, The system can start normally.
The following is the log
