Hi,
I'm trying to bringup the DWC2 USB IP version 330A on a new Stratix10 SoC and have encountered this error in both Linux and U-Boot:

Just wondering if anyone might have an idea on what could be causing this error?
Maybe some clock are not enabled ?
Hi ,
Are you following board/hisilicon/hikey/README file instructions when using U-Boot? Specially paragraph FLASHING point 4, where discussed "dwc_otg_core_host_init: Timeout!" message.
I saw that, but I don't know how that applies to a Stratix10 platform?

Hi,
Did you able to resolve this issue? If not, please provide verbose debug log and register dump.
I double-checked the clocks and it looks like all of the necessary clocks are enabled. Here are the log and register dump for U-Boot, I'll follow-up with the Linux log shortly.
For U-Boot:
