AM62A7: TI firmware builder and SBL boot mode question

Jason Zeng

Intellectual 255 points

Part Number: AM62A7

Tool/software:

SDK ver: 10_00_00_08

TI firmware builder ver:10_00_00_05

Our custom board references How to boot quickly, and we employ SBL boot method.

Q1: The DM FW is using mcu_plus_sdk_am62ax_10_00_00_14\examples\drivers\ipc\ipc_rpmsg_echo_linux\am62ax-sk\r5fss0-0_freertos\ti-arm-clang\ipc_rpmsg_echo_linux.release.appimage.hs_fs. After modifying imaging/kernels/hwa/vpac_msc/vx_vpac_msc_multi_scale_output_target.c in the TI Firmware SDK and recompiling, will the changes be updated to this DM FW? And how is the update performed?

Q2: How to compile the modified vision_apps/out/AM62A/R5F/FREERTOS/release/vx_app_rtos_linux_mcu1_0.out into an appimage after changing imaging/kernels/hwa/vpac_msc/vx_vpac_msc_multi_scale_output_target.c in the TI Firmware SDK?

Hi Jason,

Allow me some time to comment on this, expect a response in 1-2 days.

Best Regards,

Meet.

Hi Jason,
So, Firmware builder is primarily intended to be used with the Processor SDK, to build the remote core firmware in case of SPL bootflow. In case you are using SBL you can directly build the images in MCU+SDK and load them using the SBL, more information regarding that can be found here: https://software-dl.ti.com/mcu-plus-sdk/esd/AM62AX/11_01_00_16/exports/docs/api_guide_am62ax/GETTING_STARTED_FLASH.html

I assume that you still want to boot a firmware from the firmware builder using SBL, in this case I can give you some guidance:

No, This won't be reflected in the MCU+SDK.

You can use MCU+SDK tools here, this guide can help you with the same: https://software-dl.ti.com/mcu-plus-sdk/esd/AM62AX/11_01_00_16/exports/docs/api_guide_am62ax/TOOLS_BOOT.html#autotoc_md1630

So the steps would be converting .out to .rprc: https://software-dl.ti.com/mcu-plus-sdk/esd/AM62AX/11_01_00_16/exports/docs/api_guide_am62ax/TOOLS_BOOT.html#autotoc_md1630

Then generate the multicore appimage: https://software-dl.ti.com/mcu-plus-sdk/esd/AM62AX/11_01_00_16/exports/docs/api_guide_am62ax/TOOLS_BOOT.html#MULTICOREIMAGEGEN_TOOL

For HS-FS/HS-SE devices you will also have to sign the image using signing script provided in the MCU+SDK: https://software-dl.ti.com/mcu-plus-sdk/esd/AM62AX/11_01_00_16/exports/docs/api_guide_am62ax/TOOLS_BOOT.html#TOOLS_BOOT_SIGNING

Hi Meet

Our current requirement is to apply the modifications from the altered vx_vpac_msc_multi_scale_output_target.c to our ipc_rpmsg_echo_linux.release.appimage.hs_fs, or explore alternative methods to integrate the vx_app_rtos_linux_mcu1_0.out into ipc_rpmsg_echo_linux.release.appimage.hs_fs.

The ultimate objective is to modify the VPAC firmware, but we're encountering challenges regarding how to properly load and utilize the compiled outputs on the R5F core.

Specifically, if we successfully compile the vx_app_rtos_linux_mcu1_0.out into an appimage, what would be the proper procedure to combine it with the existing ipc_rpmsg_echo_linux.release.appimage.hs_fs for deployment?

Jason

Hi Jason,

I don't see a need for combining both of these, could you elaborate why you want to combine these? Just loading the vx_app_rtos_linux_mcu1_0.out converted to appimage should work, I don't think we have any way of combining these 2 appimages.

Hi Meet

Based on our understanding, the ipc_rpmsg_echo_linux.release.appimage.hs_fs contains self-reset functionality and VPAC firmware loading capabilities.

Regarding vx_app_rtos_linux_mcu1_0.out, we need clarification:

Is this solely a VPAC firmware component, or does it also incorporate the complete boot sequence and initialization routines required for normal DM R5F operation?

The critical question is: Can we directly compile vx_app_rtos_linux_mcu1_0.out into an appimage and use it independently, or does it require integration with the existing infrastructure?

BR,

Jason
