PROCESSOR-SDK-J721E: Execution of .xer5f file

Muralidharan P V

We are using Jacinto 7 board for our usecase. In the ti-processor-sdk-rtos-j721e-evm-07_02_00_06/pdk_jacinto_07_01_05_14/packages/ti/drv/i2c/example/i2c_utility directory, c file with makefile is available. We compile this c file with makefile in CCS. In ti-processor-sdk-rtos-j721e-evm-07_02_00_06/pdk_jacinto_07_01_05_14/packages/ti/binary/drv_i2c_utility/bin/j721e_evm directory, the drv_i2c_utility_mcu1_0_release.xer5f file, drv_i2c_utility_mcu1_0_release_strip.xer5f file and drv_i2c_utility_mcu1_0_release.xer5f.map file are created. Now we have a debugger connection with the board from CCS. Among the 3 files above mentioned which file we have to load in the board and how to execute the .xer5f file in the board?

Hi,

If you are loading the binaries with debugged CCS, then you can use file with the extension .xer5f. This is executable which will run on R5F core. You could also use file with "_strip.xer5f", but it does not contain symbols.

Can you tell me the procedure to load/execute this .xer5f file in the board from CCS?

Otherwise Is there any document for loading/executing the .xer5f file with step by step procedure?

It is like loading binaries/images for any other device or platform.

You will need to connect to R5F and load the binary and run it from menu Run -> Load Program option, assuming you have booted board in no-boot mode and run launch.js script to initialize and power on modules..

There are 6 R5 cores(MAIN_Cortex_R5_0_0, MAIN_Cortex_R5_0_1, MAIN_Cortex_R5_1_0, MAIN_Cortex_R5_1_1, MCU_Cortex_R5_0, MCU_Cortex_R5_1). Which one I have to connect?

When I load the program in MAIN_Cortex_R5_1_0, load program failed error occurred. How to solve this error?

When I load the program in A72 core, program is loaded but further we are not able to see any change.

Muralidharan,

For which core are you building binary?

It is not possible to load R5F binary on A72 and vice versa.

How are you building i2c utility example? Can you share the exact command line that you have used?

Also i am assuming that you are running launch.js script to run initialize DDR and other modules.

R5 core

Using make command, we built i2c utility example.

Yes. We run launch.js script
