Tool/software:
Hi,
I'd like to report a strange problem observed on the SDK10 on the J722SXH01EVM board: when booting the J722SXH01EVM board with multiple CSI cameras (say, Raspberry Pi IMX219) connected, SOMETIMES one of the csi2rx modules fails to be loaded:

We've tested two J722SXH01EVM boards with SDK10, the spontaneous error happens on both boards. This problem is not to be seen on SDK9.
Please confirm the issue and fix it. Thanks!
Best regards,
Danxuan
