Hi all,
Recently I encountered a problem. During CA53 bootup stage, PC will transfer a small executable program to the target platform via USB and then give the control to that program, which will first do PLL init. Strange point is that the PLL init part will affect USB transaction, which should have been completed. I've read the CA53 Manual, and found that it implements a in-order pipe line architecture. Does it mean instructions are executed sequentially? If yes, why the code placed after can affect the behavior before (single core, single thread)?
Any reply will be appreciated.
Thanks.
Best Regards.
It's very likely when the pll init starts, usb transfer part is not completely finished. Can you check again? If it's done by usb mass storage, it's easy to make mistake.
