    SDK V1.2.1 compile issue

    userc_41870 Aug 18, 2017 2:25 PM

      Hi,

         

      Just updated from V1.2 to V1.2.1 and compiled my project that had no issue on V1.2, after compiling it with V1.2.1, a lot of appeared, most are the simiar problems -

         

      undefined reference to CyU3PGpioInit

         

      undefined reference to CyU3PI2CInit

         

      undefined reference to CyU3PSPIInit

         

      When I selected the undefined reference function and click on "Open Declearation", I found the Declearation went to wrong position, how to fix this problem?

         

      Even I uninstall V1.2.1 and re-install V1.2, the undefined reference problem still there, so frustrated !!

          With the latest SDK, Cypress has moved some functionality to a new library (cyu3lpp.a).  Did you include this new library in your build?

            Yes. Try the following steps:

               

            1.) Open Project in Eclipse

               

            2.) Right click on the project in the Project Explorer and choose Properties

               

            3.) Choose 'Settings' under 'C/C++ Build' in the Properties box (left panel)

               

            4.) Under the 'Tool Settings' tab go to 'ARM Sourcery Windows GCC C Linker' -> 'Miscellaneous'

               

            5.) Find 'Other flags' field (bottom right) anb add the following text with quotation marks along with other paths:  "${FX3_INSTALL_PATH}\firmware\u3p_firmware\lib\fx3_debug\cyu3lpp.a"

               

            6.) Click Apply then click OK

               

            Thanks,

              Thanks sai, my problem fixed by copying Miscellaneous setting in V1.2.1 sample to my project.
