CCS/BEAGLEBK: RTOS example projects issue

Riccardo Tornese
Prodigy 55 points

Part Number: BEAGLEBK

Tool/software: Code Composer Studio

Dear TI support team, 

I have set up an sd card through the create sd-card.sh script, I have copied to SD

  1. the app file generated during the build process of GPIO_LedBlink_bbbAM335x_armTestProject
  2. and the bootloader_boot_mmcsd_a8host_debug_ti.bin from Starterware, which I have renamed to MLO

When I boot the BBB I get:

StarterWare Boot Loader

BOARDInit status [0x0]

SoC : [AM335X]

Core : [A8]

Board Detected : [BEAGLEBONEBLACK]

Base Board Revision : [UNKNOWN]

Daughter Card Revision: [UNKNOWN]

Copying application image from MMC/SD card to RAM

Jumping to StarterWare Application...

but the led never starts to blink.

Using the same MLO, I am able to run gpio_app_led_blink_a8host_debug_ti.bin in the starterware/binary/gpio_app_led_blink/bin/am335x-evm .

I am also able to run the GPIO_LedBlink_bbbAM335x_armTestProject in CCS using the JTAG debugging. 

When I run the MLO and app in processor_sdk_rtos_am335x_4_02_00_09/prebuilt-sdcards/evmAM335x , I get

StarterWare Boot Loader 

BOARDInit status [0x0]

 SoC                   : [AM335X]

 Core                  : [A8]

 Board Detected        : [BEAGLEBONEBLACK]

 Base Board Revision   : [UNKNOWN]

 Daughter Card Revision: [UNKNOWN]

Copying application image from MMC/SD card to RAM

Jumping to StarterWare Application...

 I2C Test: 400Kbps: Data Mismatch 

 I2C Test: 100Kbps:Data Mismatch 


 Some tests have failed.

I have noticed that the _c_int00 of the executable of GPIO_LedBlink_bbbAM335x_armTestProject is loaded after 0x80000000  . May this be the cause of the problem? Should I use a different bootloader?

Here more info about my configuration:

os : ubuntu 16.04

sdk: processor_sdk_rtos_am335x_4_02_00_09

ccs: 7.3.0.00019

BBB revision : C

    Riccardo,

    Thanks for providing the information regarding the version of the SDK that you are using and providing specific information on what is working with your setup vs what is not.

    I have been able to reproduce the issue that you are running into and can confirm that there is a known issue with using bootloader from this release with TI RTOS LLD examples that seems to have been introduced with the ARM GCC compiler update that came in the late for the PRSDK 4.02 version of the SDK.

    It is unclear to me if the issue is caused due to ARM init code in the bootloader which causes an exception when RTOS LLD example is loaded or if there was an issue in the OSAL layer that has fixed this issue but I picked up the evaluation version of the upcoming PRSDK v4.03   release and can confirm that this issue is resolved.

    PRSDK403_testbinaries.zip

    I have attached the binaries from the PRSDK 4.03 release for you to confirm with your setup. The release should be available on ti.com in the next couple of days.

    Regards,

    Rahul

    Hi Rahul,
    thank you for the info and for the binaries. The attached binaries work fine.
    I have also tried to install the SDK 4.03 and to compile the examples. However the compiled app of the blink_led example and the compiled starterware bootloader for sd do not work.
    Do you have some hints?

    Thanks,
    Riccardo

    Richardo,

    Can you provide your binaries here. Have you also tried to boot the app using the MLO.
    It would be good for me to try your binaries to see if I can reproduce this issue.

    Regards,
    Rahul

    Hi Rahul,

    here are the binaries. I have also tried the MLO that you have provided me, but it does not work.

    Hi Rahul,
    have you checked the binaries I have sent in the previous message? Do you have suggestions?
