I am trying to build the boot-emac-flash project in CCS. I am getting error in htons() in bl_emac.h as in attached image.

Similarly, if I build boot_serial project in CCS. "error #395: pointer to incomplete class type is not allowed" occurred for htons() in bl_emac.h. I couldn't build any of the bootloader code. Kindly help me to resolve this issue.

    Hi,

      Did it work in the past? Did you import the boot_emac_flash project into CCS? Did you change the stock example in any way? The example is supposed to work, at a minimum compile without issues out of the box. 

    I will suggest you do the following.

    - Create a new CCS workspace. I don't know what happened in the past. Perhaps some CCS meta files was corrupted. Starting with a new CCS worksapce to rule that problem. 

    - Import boot_emac_flash into CCS. Note this is an import, not a directory or files copy. To import the project, you will need to select File -> Import. 

    - Select it is a CCS Projects. 

    - For Select search-directory, use the Browse button to select the project at C:\ti\TivaWare_C_Series-2.2.0.295\examples\boards\ek-tm4c1294xl\boot_emac_flash. The CCS will detect the project and you just import it. 

    - Once the project is imported, just build the project. It should build with no errors.

    Thanks for the solution.

    While trying to open CCS file, meta file issue was observed. So opened as project raised this issue.

    I tried to open in new workspace. and Build. Got error in bl_startup_ccs.s for "GPIOIntHandler" even UART_ENABLE_UPDATE and UART_AUTOBAUD are disabled (not sure for the reason for this). So commented those as ethernet is needed. Deleted "TARGET_IS_TM4C129_RA2" and added "TARGET_IS_TM4C129_RA0" and "TARGET_IS_TM4C129_RA1" in predefined symbol setting. Then I could compile the code.
