Cypress PSOC - CY8C4248LQI-BL483 Fails Verify and Operation

  • To whom it may concern,
    The Cypress PSOC - CY8C4248LQI-BL483 in SWD mode fails to verify and upon power cycling the programmed device no functionality is available. I am programming this device using the CY8C4248LQI-BL493 scripts which could be part of the problem but no 483 scripts exist.



  • FWIW I'm using the cyclone universal FX to program this device.

    • Hi Nicolas,

      First thing I would try is reducing the debug shift frequency to see if the verify error goes away. If that doesn't solve the issue, I suggest submitting a support request and attaching your object file. We have a CY8C4248 evaluation board at P&E that we can test against.

  • I tried shifting debug frequency prior to submitting this bug report. I'll open a support request thanks!
