AM5728: .Bin without rprc

Nancy Wang

Part Number: AM5728

Hi,

The customer generated .bin with CCSV7 which is not available in uboot and the .bin can be used successfully in SBL. After comparison, he found the SBL has function that deal with rprc file, but he didn't deal with it in his uboot.

He tried this instruction to convert .out to .bin

${TI_PDK_INSTALL_DIR}/packages/pdkAppImageCreate.bat ${TI_PDK_INSTALL_DIR}/packages ${CG_TOOL_ROOT} ${PROJECT_LOC}/${ConfigName} ${ProjName} AM572x dsp

So how to generate .bin file without rprc file？

Nancy,

Your customer seems to be mixing two environments. Uboot is the secondary bootloader for A15 Linux users and SBL is the secondary bootloader for RTOS/bare-metal developers. Uboot is a community developed software and is primarily responsible only to boot Linux OS on the A15 core and doesn`t boot/load slave cores.

On the other hand SBL is light weight TI provided bootloader for RTOS/bare-metal use case which doesn`t have as many services as uboot but also provides ability to quick boot application on slave cores. The two environments can`t be mixed and matched.

For Linux users wanting to load application on slave cores, we provide remote-proc and IPC mechanism that can be used to deploy firmware to slave cores. Also, TI automotive teams had provided a reference path for early boot/late attach but this feature is not supported in the Processor SDK since the feature was not upstreamed/accepted in the mainline.

If quick booting slave cores is not a requirement then IPC/remoteproc is the recommended approach as you can see from the detailed article that we have created here:

Hope this helps.

Regards,

Rahul

Just in case that I have not understood the usecase correctly, I would also like to provide guidance on creation on .bin from .out file. The conversion is done use GCC utility called objcopy

Hope this helps.

Hi,

How to use objcopy utility in ccs to convert .out to .bin?

I Have tried to use TOOLCHAIN_PATH_<A8/A9>/bin/arm-none-eabi-objcopy -O binary <application>.out <application>.bin in figure 2, but i cannot find my .bin file. Please help give detailed steps, so that i can reply to customer quickly.

Or use post-build instruction to execute it.

I have only seen this being used in the post build script. Please try to add the following to the post build script:

${CG_TOOL_PATH}}/bin/arm-none-eabi-objcopy -O binary ${APP_NAME}.out ${APP_NAME}.bin

Make sure full path of CG_TOOL_PATH and APP_NAME is provided in the environment. You can also create a batch script that you can invoke from the post build configuration option. You can also refer to pdkAppImageCreate script in the location on using a scripted way to invoke the utility: pdk_am335x_1_0_13\packages

Rahul
