fx3 multi configuration

BBKi_4523881 · ‎Oct 16, 2019

Hi,

I am trying to expand the bulk loop example so that the firmware to contain additional configurations.

I duplicated the CyFxUSBHSConfigDscr array in cyfxbulklpdscr.c to and changed the configuration number and number of configurations on the device descriptor.

a "stall" is returned when the host tries to configure the device (set-configuration).

do you have any ideas or code examples for this issue?

thanks,

Gal

Hello,

Please find the attached firmware, which doesn't use fast enumeration CyU3PUsbRegisterSetupCallback(CyFxBulkLpApplnUSBSetupCB, CyFalse); by setting second parameter to CyFalse. Due to this the application handles all the setup packets.

The application is passing two different configuration (High speed configurations). Please check it at your end by probing the USB lines.

Let me know the results

I have checked it at my end. Please refer to the USB traces attached

Regards,

Rashi
