J721EXCPXEVM: J721EXCPXEVM: Procedure to generate DRA821/J7200 RTOS SD card image

Hello,

Apologies for the delayed response. By default Linux SDK has the R5F firmware which is a minimal ipc echo test examples.
You can start with Linux SDK and then go on to build ipc examples from the RTOS SDK.

Hi Keerthy,

Thank you for your response. I am trying to run U-Boot on A72 and RTOS/other apps on R5 cores.
I would like to share the steps that I followed.

Document referred:
<PDK>/docs/userguide/j7200/boot/boot_k3.html#building-the-sbl-and-its-componentsfile

Step 1.:  Compiling SBL for GP device to a [.tiimage] file
Command executed:
cd <PDK>/packages/ti/boot/sbl/build
make clean all
This is supposed to generate [sbl_mmcsd_img_mcu1_0_release.tiimage] and [sbl_mmcsd_img_hlos_mcu1_0_release.tiimage] under the folder:
<PDK>packages\ti\boot\sbl\binary\j7200_evm\mmcsd\bin

Results are as follows on ti-processor-sdk-rtos-j7200-evm-xx_xx_xx_xx:
Version 11_00_00_03 : Compilation error, doesn't generate .tiimage files
Version 08_02_00_05 : Compilation error occurs, but generates the .tiimage  files.
Version 10_01_00_04 : Compilation error occurs, but generates the .tiimage  files

Step 2.: Generate [.appimage] for HLOS+RTOS image
Step 2.1: Create a folder and copy the ATF, OPTEE, U-Boot-SPL images to that folder.
Eg: Copy bl31.bin, bl32.bin, A72 u-boot-spl.bin to the folder /home/work/e-drive/DRA821/J721EXCPXEVM/SDK_11_00_10_01/PROCESSOR-SDK-RTOS-J7200/ti-processor-sdk-rtos-j7200-evm-08_02_00_05/HLOS-files/

Step 2.2: Modify the following variables in file [<PDK>\packages\ti\boot\sbl\tools\combined_appimage\config.mk]
HLOS_BIN_PATH ?= /home/work/e-drive/DRA821/J721EXCPXEVM/SDK_11_00_10_01/PROCESSOR-SDK-RTOS-J7200/ti-processor-sdk-rtos-j7200-evm-08_02_00_05/HLOS-files/
HLOS_BOOT ?= development
IMG1 ?= mcu1_0,$(PDK_INSTALL_PATH)/ti/boot/sbl/example/k3MulticoreApp/binary/j7200/sbl_baremetal_boot_perf_j7200_evm_mcu1_0TestApp_release.xer5f
IMG2 ?= mcu1_1,$(PDK_INSTALL_PATH)/ti/boot/sbl/example/k3MulticoreApp/binary/j7200/sbl_baremetal_boot_test_j7200_evm_mcu1_1TestApp_release.xer5f
IMG3 ?= mcu2_0,$(PDK_INSTALL_PATH)/ti/boot/sbl/example/k3MulticoreApp/binary/j7200/sbl_baremetal_boot_test_j7200_evm_mcu2_0TestApp_release.xer5f
IMG4 ?= mcu2_1,$(PDK_INSTALL_PATH)/ti/boot/sbl/example/k3MulticoreApp/binary/j7200/sbl_baremetal_boot_test_j7200_evm_mcu2_1TestApp_release.xer5f

Step 2.3: 
Execute the command
cd <PDK>/packages/ti/boot/sbl/tools/combined_appimage
make BOARD=j7200_evm

Result: The binary file [combined.appimage] is generated under the folder:
<PDK>\packages\ti\boot\sbl\tools\combined_appimage\bin\j7200_evm

Step 3. Copy files to SD card.
Copy the file [sbl_mmcsd_img_hlos_mcu1_0_release.tiimage] to the SD card and rename it to [tiboot3.bin].
Copy the file [combined.appimage] to the SD card and rename to [app].
Copy the TIFS file [tifs.bin] found in <PDK>/packages/ti/drv/sciclient/soc/Vx to the SD card.

Result on Booting from SD card:
The R5 apps run, but U-Boot SPL does not run on A72.

Please let me know if you have any tips.

Thank you.

Hi Aiyappa,

Thanks for the steps. I’ll test them on my side and update you tomorrow.

Hi Aiyappa,

Could you please refer the attached HLOS Boot procedure , let us know if this helps.

Hi Karthik,

Thank you for your reply and the instructions.
I appreciate that you took the effort to look into the problem.

However, when I try Step 3.2 [make BOARD=j7200_evm sbl_mmcsd_img_hlos -sj], the following error is displayed:
make: *** No rule to make target 'sbl_mmcsd_img_hlos'.

I am using ti-processor-sdk-rtos-j7200-evm-11_00_00_03 and am running the build from the directory
 <pdk install path>/packages/ti/boot/sbl/build
 
On a different note, executing [make clean; make all BOARD=j7200_evm] results in the following error:
/packages/ti/boot/sbl/build/sbl_multicore_boot_test.mk:30: force_multi_core_img_gen.c] Segmentation fault (core dumped)

[sbl_mmcsd_img_hlos_mcu1_0_release.tiimage] is still created though under the folder
<pdk install path>/packages/ti/boot/sbl/binary/j7200_evm/mmcsd/bin

I followed the rest of the instructions and created the SD card, but an error occurs during boot in U-boot SPL and the target keeps rebooting.
Since the entire process is not working as expected, I'll let it rest for now.
Perhaps I'll pursue this problem when I have some free time in the future.

Thank you.
Best regards,
Aiyappa

Hi Aiyappa,

Could you please build from below  directory.

<pdk install path>pdk_j7200_11_00_00_21/packages/ti/build$ make BOARD=j7200_evm sbl_mmcsd_img_hlos -sj
