RTOS/TMDSEVM437X: GPIO Example Project undefined USE_BIOS

U-SK
Genius 5840 points
Part Number: TMDSEVM437X

Tool/software: TI-RTOS

Hello,

I would like to GPIO_LedBlink in processor SDK not using TI-RTOS.

So I created and imported GPIO_LedBlink project to CCS.

Moving USE_BIOS to Undefine symbols in properties, and executed build. 

Then, following error is displayed.

Description Resource Path Location Type
gmake: *** [all] Error 2 GPIO_LedBlink_evmAM437x_armTestProject C/C++ Problem

I attached text file described contents of console.

    U-SK,

    The build failure is caused because there is Task statically created in the .cfg file with the name gpio_test which gets commented when you undefine USE_BIOS. the name of the function become main(). If you notice the test project provided along with the GPIO LLD is linked to a .cfg and project settings is setup for XDC tools and GCC which indicates that the project is setup for RTOS. This project can`t be used as is for bare-metal setup.  I would recommend the customer to use GPIO example from diagnostics

    http://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/index_board.html#diagnostics 

    The diagnostic bar-metal example uses makefile for compilation and not CCS. There is currently no readily available CCS project for GPIO LLD in bare-metal mode. The only example is based on makefile.  If CCS compilation is required then the customer will need to create a CCS project from scratch starting with simple hello world and then replace the main.c with source files form GPIO LLD example and apply the build options carefully including undefine USE_BIOS.

    1. Generate basic hello world using 

    http://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/index_examples_demos.html#id48

    2. Remove main.c and .lds file and add source files from GPIO LLD RTOS example except the .cfg. Add linker command file from pdk_am43xx_1_0_13\packages\ti\board\diag\common\AM437x

    3. Copy all the GCC compiler and linker options and undefine USE_BIOS. Ensure remove unused sections and group libraries for backward references

    4. For linking you need to link board, gpio, spi, i2c, uart , csl and csl init libraries  as explained in screenshot here:

    http://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/index_faq.html#device-drivers 

    Also note, all the drivers provided by TI call into an OS abstraction layer. We provide two versions of the OSAL layer. One for bare-metal and the other one for RTOS so they would need to link into the nonos version for bare-metal setup as described below:

    Also, for linking libraries from PDK to bare-metal code in CCS, you need to use the technique described here:

    Rahul
