I also doubt it. I find a OK device, and read it by programmer, the data is OK, it display after read "43 ef 56 .. etc.". Then I burn my firmware in it, and read it, it display "xx xx xx ..." again. So, I think the hardware is OK. My programmer version is 3.25.0
Where should I turn off the "protection" ? I can't find the option in programmer.

3. Re: about proc program issue
sz1y7_2045441 Nov 20, 2016 9:17 PM (in response to sz1y7_2045441)I download the sample of "CE63793 - CSD Software Filters with EzI2Cs Slave on CY8C20xx6", then I open PSoC Designer 5.4 and create a new project by CLONE this sample code, select the device "CY8C20336A-24LQXI". As the sample code is for CY8C20666, it show some warnings, but I select "clone", it create the project, then I build and burn it, and read it by PSoC programmer 3.25.0, the result again "xx xx xx ..." :(
I do another test, I openthe Designer and create a new project with the "Target Device: CY8C20336A-24LQXI", and then build it without add another thing in the project, and burn it to the device, and read, it again "xx xx xx ...". I have no idea now.
BTW, my chip print CY8C20336A, but the programmer is always "Automatically Detected Device: CY8C20336-24LQXI". Is that right?
