TDA4VM-Q1: What is the tifs.bin?

Part Number: TDA4VM-Q1

Hi,

expert.

I'd like to know tifs.bin file.

Do I use different tifs.bin file in Custom HS-FS and Ti dummy key HS-FS?

I have two custom board keywrited by Custom key and Ti dummy key.

The Ti dummy key board works well but the Custom key board can't boot to the tifs.bin step.

I use the tifs.bin in SDK7_1 patched ES1_1 files. I signed the tifs.bin with each key.

In sciclient_rom.c stucked

In sciclient_secureproxy.c

Please guide.

Thank you.

    Hi Youngwoo,

    tifs.bin that you copy or flash onto your boot media is the signed TIFS firmware with customer keys. The binary is concatenated together from the following 3 components: Cust.key signed outer certificate + TI Keys signed inner certificate + TIFS HS Encrypted Binary.

    The second and third binaries are provided in the TI RTOS SDK in the path <RTOS_SDK>/<PDK>/packages/ti/drv/sciclient/soc/sysfw/binaries. The binaries will be different between Silicon Revisions of the SoC, given that the TI Keys are different. These binaries are ti-fs-firmware-j721e-hs-cert.bin & ti-fs-firmware-j721e-hs-enc.bin for SR1.0 and ti-fs-firmware-j721e_sr1_1-hs-cert.bin & ti-fs-firmware-j721e_sr1_1-hs-enc.bin respectively for SR1.1.

    The combined image will be generated as tifs-hs-enc.bin for SR1.0 and tifs_sr1.1-hs-enc.bin for SR1.1. Please use the latter image for your device.

    regards
