Do you have a simple project to blink LED?
Please tell me how to start R5F from OSPI FLASH.

CCS Version is 9.0.0.00018 .

Hi,

There are two example projects provided in PRSDK for blinking an LED.

GPIO LLD example:

docs: http://software-dl.ti.com/processor-sdk-rtos/esd/docs/06_01_00_08/rtos/index_device_drv.html#id22
build for R5F: gmake gpio_apps LIMIT_SOCS="am65xx" LIMIT_BOARDS="am65xx_evm" LIMIT_CORES="mcu1_0 mcu1_1"
resulting executable and SBL app image are located <PDK>/packages/ti/binary/GPIO_Baremetal_LedBlink_TestApp/bin/am65xx_evm

The CSL GPIO example is named csl_gpio_toggle_app.

build all CSL examples for R5F: gmake csl_apps LIMIT_SOCS="am65xx" LIMIT_BOARDS="am65xx_evm" LIMIT_CORES="mcu1_0"
resulting executable is located in: <PDK>/packages/ti/binary/csl_gpio_toggle_app/bin/am65xx_evm

The boot flow, tools, etc. are documented at these locations:

Regards,
Frank

Hi Frank,

Thank you for the detailed explanation.

Thanks to that, I was able to move forward a little.

The following files were created by compiling pdk_am65xx_1_0_4.

Folder: C:\ti\pdk_am65xx_1_0_4\packages\ti\binary\csl_core_r5_baremetal_test_app\bin\am65xx_idk
2020/01/14 12:00 22,508 csl_core_r5_baremetal_test_app_mcu1_0_release.appimage
2020/01/14 12:00 24,322 csl_core_r5_baremetal_test_app_mcu1_0_release.appimage.signed
2020/01/14 12:00 22,476 csl_core_r5_baremetal_test_app_mcu1_0_release.rprc
2020/01/14 12:00 401,964 csl_core_r5_baremetal_test_app_mcu1_0_release.xer5f
2020/01/14 12:00 59,583 csl_core_r5_baremetal_test_app_mcu1_0_release.xer5f.map
2020/01/14 12:00 22,508 csl_core_r5_baremetal_test_app_mcu1_0_release_BE.appimage

Q1) Is this result correct?

Q2) Or is it a different folder?

Q3) Can I write 'csl_core_r5_baremetal_test_app_mcu1_0_release.appimage' to AM65x using UniFlash?

Q4) Or do you need to convert with 'tiimage.exe'?

AM65x is not listed in UniFlash I have.

Q5) Choose another device name?

Regards,

Hi Yoji,

Q1 & Q2) Build the SDK is documented here: http://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/index_overview.html#building-the-sdk

Building PDK is documented here: http://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/index_overview.html#rebuild-pdk

Issue this on the command line to get build help from the <PDK> installation directory (e.g. <PRSDK>/pdk_am65xx_1_0_6): gmake help

The CSL build output can be redirected to a build log as follows: (note gmake is used on Windows, make is used on Linux):

gmake csl_apps LIMIT_SOCS="am65xx" LIMIT_BOARDS="am65xx_evm" LIMIT_CORES="mcu1_0" > build_log.txt 2>&1

This log can be inspected to determine where the build output is placed.

For the CSL GPIO test app, I expect the output to be located in <PDK>\packages\ti\binary\csl_gpio_toggle_app\bin\am65xx_evm. The output files for the default build include:

csl_gpio_toggle_app_mcu1_0_release.xer5f
csl_gpio_toggle_app_mcu1_0_release.xer5f.map

By default, the application image for this GPIO test which is used by the SBL isn't created during build. Please see documentation under http://software-dl.ti.com/processor-sdk-rtos/esd/docs/06_01_00_08/rtos/index_Foundational_Components.html#building-the-sbl-and-its-components, Section "Converting ELF executables to SBL loadable image" for details on building this image. For example, I added the following lines to <PDK>\packages\ti\csl\csl_component.mk to create the image during the build of the GPIO test:

csl_gpio_toggle_app_SBL_APPIMAGEGEN = yes
export csl_gpio_toggle_app_SBL_APPIMAGEGEN

Q3-Q5) The generated .appimage can be written to flash using Uniflash. Please see the documentation here:

http://software-dl.ti.com/processor-sdk-rtos/esd/docs/06_01_00_08/rtos/index_Foundational_Components.html#id108,
