  • Unable to use RTT with J-Scope on Cypress PSOC4

    Hi,

    I'm trying to use J-Scope to instrument data on a Cypress PSOC4 device (CY8C425, segger.com/evaluate-our-softwa…r/psoc-4-development-kit/). HSS method in Ozone works fine and I was trying out the RTT method using J-scope. I'm not able to use the 3 phase sine example included in the J-Scope installation due to limited RAM in the micro-controller I'm using the most basic function (attached) to check how this RTT would work.

    So far I'm not having any luck. I can see the control block and data format are correctly identified but no data is coming through. Can someone take a look at the code I have and try to see it works on their end?

    Thanks,
    John
