Hi Bob,

When you are getting this print in kernel ?

Are you getting this print continuously from kernel starts to boot ?

What SDK and version are you using ?

Hi ,

When you are getting this print in kernel ?

I get the print during the kernel booting.

Are you getting this print continuously from kernel starts to boot ?

Only once.

What SDK and version are you using ?

ezsdk_5_05_02_00_dm814x.

Hi Bob,

How did you drive the "DRV_VBUS" ie from internally or externally providing voltage ?

Have you initialized the "DRV_VBUS" in board file (need to configure as a output ) and setting the pinmux registers correctly ?

Hi Titus,

How did you drive the "DRV_VBUS" ie from internally or externally providing voltage ?

We're using externally providing voltage .

Have you initialized the "DRV_VBUS" in board file (need to configure as a output ) and setting the pinmux registers correctly ?

I have set the pinmux register "usb0_drvvbus" correctly,but I don't know how to configure the register as output.

Please help.

Thank you.

Hi Bob,

You have to configure the DRV_VBUS as output through pinmux registers.

Please refer the following TI E2E link as yours.

Hi Titus,

Maybe I should do like the link you give me.

But I don't know how to understand "setup_usb(500, 8);".

Hi Bob,

Please refer the location in your kernel source for "setup_usb.c" or "davinci_setup_usb".

Hi Bob,

DM365 USB ERROR "VBUS error workaround "

Sorry, I'm wondering that DM365 is a OMAP processor..

DM365 is the Davinci Platform, could you please direct me if I'm in wrong path.
