Hello Team,

I am working for a bootloader project.

Currently, bootloader is loaded into RAM using CCS.

Now i would like to flash bootloader into external flash using Uni Flash tool.

Could you please provide any supported process document, to create bootable ti image of my application.

My understanding from your question says that you should be ramping up on understanding Secondary Bootloader - https://dev.ti.com/tirex/explore/node?node=A__AcihA9ANR54nmG9pF-hOHg__AM26X-ACADEMY__t0CaxbG__LATEST

Also a little bit more about the tools provided by MCU+ SDK - https://dev.ti.com/tirex/explore/node?node=A__AE-ozIYMUrJo3Go63N5zBQ__AM26X-ACADEMY__t0CaxbG__LATEST

If you have gone through the context and you require any specific information, please ask pointed question so I can support better.

Best Regards,
Aakash

Hi Aakash,

Yes, it is a SBL and want to flash it onto the ext flash.

I have gone through the documentation.

Now, i have working SBL .elf/.bin file. The file is generated outside of CCS but same compiler.

As per my understanding flashing my bin/elf will not work directly so i need to convert it to .tiimage file, correct me if i am wrong.

Demo application compiled with CCS, generates a .appimage file, similar to this SBL needs a .tiimage file.

Could you please let me know how to convert my elf/bin file to tiimage format or can flash my SBL bin file directly on ext flash using UniFlash.

*I have created a metaimge for SBL on AWR1843Boost using ImageCreator scripts from TI.

Similarly looking for AM2634.

Kind regards

Hari

You can refer to this makefile - <SDK>/examples/drivers/boot/sbl_null/am263x-cc/r5fss0-0_nortos/ti-arm-clang/makefile

Hi Askash,

Now, able to generate TI Image from BIN image.

Below sequence is used to generate

$(BOOTIMAGE_CERT_GEN_CMD) --image-bin $(BOOTIMAGE_PATH)/$(BOOTIMAGE_BIN_NAME) --core R5 --swrv 1 --loadaddr $(SBL_RUN_ADDRESS) --sign-key $(BOOTIMAGE_CERT_KEY) --out-image $(BOOTIMAGE_PATH)/$(BOOTIMAGE_NAME)

Q) which one, i have to use it from below image?

I have used only 2nd one.

Hi Hari,

If your device is HSFS, then you should be using second one or else in case of HSSE you should be using the other options.

I hope this helps.
