fx3 j link segger debug

[gean_3054931]

Hello,

i am using j link segger to debug fx3 firmware,when i am doing step by step debug by putting breakpoints, the event  CY_U3P_USB_EVENT_RESET is going to call many times? and its not going to the event state CY_U3P_USB_EVENT_SETCONF even with USB2.0 is connected to our fx3 custom board?what whould be the reason?

thank you.

Since you are step into each line of firmware manually using the JTAG debugger, the USB call backs are getting time out.

Place a single break point after the connectstate API and remove all other break points.
