CCS/TDA2EVM5777: SYS_BIOS enabled application generation fails for Cortex A15

Part Number: TDA2EVM5777

Tool/software: Code Composer Studio

Hi,

We have a Linux based working application that needs Ethernet, QSPI Flash and UART periperals

Now to prove portability of POSIX, we have chosen TI_RTOS (since the target used is TI TDA2XX / EVM) and as per TI recommendation & literature supported, we work in the Code Composer Studio IDE 

Until now we are able to successfully 1) build & flash the SBL 2) generate the imported demo projects - Hello World, Basic NIMU example

But for past 1 week we are working with our customized application within CCS / TI_RTOS. i.e., created a separate C/C++ based CCS project and added our customized application source files. Although we are able to compile the code by fixing or enabling all required properties, we have hit a road block of Linker errors in so many files & functions.

At this juncture, kindly provide sufficient information and recommend us on the possible paths now

[A] continue within CCS, set the right configuration & properties, get it linked and generate application

[B] peruse the generated makefile (as outcome of basic NIMU example run already) and extend that into our application by additionally copying the dependent libraries & headers into our appropriate directories i.e.,  avoid CCS based properties/configuration settings.

Kindly let me know if I should share all the needed snapshots and error statements here so that you can quickly & efficiently get back with the best time saving option.

Thanks,

Sathiyan
