CCS/AM5728: LED blink project question

Part Number: AM5728
Other Parts Discussed in Thread: CCSTUDIO, SYSBIOS

Tool/software: Code Composer Studio

Hi there,

I'm trying to work through the steps in "http://processors.wiki.ti.com/index.php/Linux_IPC_on_AM57xx#Adding_IPC_to_an_existing_TI_RTOS_application_on_the_DSP" 

However, there doesn't appear to be a configuration for building out GPIO_LedBlink_evmAM572x_c66xExampleProject using " ./pdkProjectCreate.sh AM572x evmAM572x little gpio all dsp"

The only boards I can see are listed below - no file for AM572x SoC...

./ti/drv/gpio/test/led_blink/k2e/c66/bios/gpio_test.cfg
./ti/drv/gpio/test/led_blink/am571x/c66/bios/gpio_test_idkAM571x.cfg
./ti/drv/gpio/test/led_blink/c6678/c66/bios/gpio_test.cfg
./ti/drv/gpio/test/led_blink/am574x/c66/bios/gpio_test_idkAM574x.cfg
./ti/drv/gpio/test/led_blink/k2l/c66/bios/gpio_test.cfg
./ti/drv/gpio/test/led_blink/k2h/c66/bios/gpio_test.cfg
./ti/drv/gpio/test/led_blink/c6657/c66/bios/gpio_test.cfg
./ti/drv/gpio/test/led_blink/k2g/c66/bios/gpio_test_ice.cfg
./ti/drv/gpio/test/led_blink/k2g/c66/bios/gpio_test.cfg

If I use the propject included on the webpage (http://processors.wiki.ti.com/images/c/c9/GPIO_LedBlink_evmAM572x_c66xExampleProject_with_ipc.zip


make: *** target pattern contains no '%'. Stop. subdir_rules.mk /GPIO_LedBlink_evmAM572x_c66xExampleProject_with_ipc/Debug line 6 C/C++ Problem

The subdir_rules.mk error looks to be because the zipped project was built out on a Windows build host:

GPIO_evmAM572x_board.obj: /C:/ti/pdk_am57xx_1_0_4/packages/ti/drv/gpio/example/led_blink/src/am572x/GPIO_evmAM572x_board.c $(GEN_OPTS) | $(GEN_HDRS)
@echo 'Building file: "$<"'
@echo 'Invoking: C6000 Compiler'
"/home/dmurphy/ti/ti-cgt-c6000_8.2.2/bin/cl6x" -mv6600 --include_path="C:/ti/pdk_am57xx_1_0_4/packages/ti/drv/gpio" --include_path="/home/dmurphy/ti/ti-cgt-c6000_8.2.2/include" -g --define=SOC_AM572x --define=EVM_AM572X --define=USE_BIOS --define=C66X --define=NSS_GEN2 --display_error_number --diag_wrap=off --diag_suppress=1111 --diag_suppress=827 --diag_suppress=824 --diag_suppress=837 --diag_suppress=1037 --diag_suppress=195 --diag_suppress=77 --diag_suppress=232 --diag_warning=225 --diag_warning=994 --diag_warning=262 --preproc_with_compile --preproc_dependency="GPIO_evmAM572x_board.d_raw" $(GEN_OPTS__FLAG) "$(shell echo $<)"
@echo 'Finished building: "$<"'
@echo ' '

So I'd prefer to be able to build out the project on my Linux build host rather than trying to troubleshoot the project zip file from the web page.

Is there a ./ti/drv/gpio/test/led_blink/am571x/c66/bios/gpio_test_idkAM571x.cfg equivalent file for AM572x SoC & evmAM572x board?

Any suggestions welcome.

Thanks,

Dermot

    Hi,

    It looks that you are looking for a GPIO test example on AM572x GP EVM, C66x core. I am not sure what Processor SDK RTOS release you worked with, here is mine, the latest 5.0 release:

    Thanks for your reply, Eric.

    I have been using the Processor SDK Linux/RTOS 4.3 which has no GPIO_LedBlink project for DSP at all. I've been trying to work through the document linked here:
    processors.wiki.ti.com/.../Linux_IPC_on_AM57xx
    ...which makes reference to running the GPIO_LedBlink_evmAM572x_c66xExampleProject on a DSP core. Like you, I also tried the Processor SDK 5.0 which does have the GPIO_LedBlink_evmAM572x_c66xTestProject if not the GPIO_LedBlink_evmAM572x_c66xExampleProject code.

    Do you know if there are significant differences between Example and Test projects or could they be used interchangeably?

    I'm also able to build out GPIO_LedBlink_evmAM572x_c66xTestProject successfully under the 5.0 SDK although when it comes to loading it onto DSP core I do get that data verification error but that's another issue which I may look at troubleshooting further if I get time. I know it's generally related to memory mismatches between the linker, debugger and device under test.

    Reference: processors.wiki.ti.com/.../Troubleshooting_CCS_-_Data_Verification_Errors

    Hi,

    The RTOS example are intended to be run in no-boot load, using CCS/JTAG. It may not work if you use Linux to load and run, you may need to resolve resource conflict.

    The difference between test and example projects: example project is simple. The test project has more coverage, e.g, it may test more API and configurations.

    Thanks for following up, Eric.

    I think it would be nice if there were some one or two projects in the PDK which were capable of running under a default Arafgo Linux build without the risk of a resource conflict. Or even better, an example designed to be used with the document: processors.wiki.ti.com/.../Linux_IPC_on_AM57xx

    This could be a very valuable document to anybody trying to learn IPC if the code references and steps were fully validated.

    Thanks again,
    Dermot
