Why debugger reports: No source available for "0x0"?

[doch_3739346]

Tried "Terminate and Relaunch", reboot PC, but still got the error.

From GDB Server, it shows: Target halted (PC = 0x00000000).

Hello Dong Chen,

-Please let me Know, are you using super-speed explore kit(CYUSB3KIT-003 development kit ) or FX3 DVK kit(CYUSB3KIT-001 development kit)?

-The CY7C65215 Cypress USB Serial part on the CYUSB3KIT-003 development kit provides a debugger interface that works with OpenOCD.

Regards,

Hello Dong Chen,

If you are using CYUSB3KIT-003 development kit following items has to be checked before doing the JTAG debug:

1. In the Control center three devices should be present as shown in the below image.

2. If Cypress USB Bootloader device is missing - then please check the PMODE pins of FX3 whether it indicates USB Boot. If it is there then please check whether the device is bound to any other driver in the device manager. If yes, then please update the driver to Cypress cyusb3 (which can be found in FX3 SDK)

If the above are fine, Please refer "EzUsbSuite_UG.pdf. chapter 3.2 of the document explain the JTAG debugging steps in detail. Please follow the same and let us know if you are still facing the issue. The document can be found in the FX3 SDK installation directory.

Regards,

Anil Srinivas.
