Hi, TI engineers,
We are trying to bring up the board with SoC TDA4VM SR1.1 HS-FS, We using HLOS SBL boot flow, but when running into the SBL, an error "TIFS load...FAILED" was occured.
The tifs.bin we are using from the path: "cp pdk_jacinto_08_04_00_21/packages/ti/drv/sciclient/soc/V1/tifs.bin"
Our SDK version:
LINUX SDK: 08_04_00_11
RTOS SDK: 08_04_00_06
Can you give me some guide to fix this problem?
BRs,

Hi Xie,
The booting of HS-FS devices is not supported in SDK 8.4. You need to move to the latest 9.x SDK (9.1+) for HS-FS support on J721E SR1.1 SoCs.
The tifs.bin is the TIFS binary for a GP device. The HS-FS binary for J721E SR1.1 SoCs has a file name of tifs_sr1.1-hs-fs-enc.bin in the packaged SDK. It needs to be copied over as tifs.bin onto your SDCard/eMMC partition, or flashed in the same position as you would for a tifs.bin binary.

Hi, Suman,
Thanks for your reply.
Do I have to migrate to 9.1sdk and is there a way to adapt the hs-fs chip on 8.4 sdk?

Hi Xie,
I recommend you to move to the latest SDK if the intention is to keep the devices in HS-FS state only, but still have the device booted regularly.
The older SDKs only supported GP and HS-SE. The technical debt is very high to add HS-FS support onto older SDKs.

Hi,Suman,
Thanks for your response.
Our mass-produced project is based on 8.4 SDK, so we really hope to support HS-FS devices on this SDK version, otherwise it may increase our development cycle and project milestones are not allowed. Please help to see if there is a solution

Hi, Suman,
Can I burn the TI dummy key into an HS-FS device through keywriter and convert it into HS-SE-TIDK device? Does 8.4 SDK support TI-SE-TIDK devices?
BRs.

Hi, Suman,
Thank you.
Do you have the latest guidance documents for burning Key ?

Hi, Suman,
I refer to this document: https://www.ti.com/lit/pdf/sprad04?keyMatch=HS-FS
and get ti_fek_public.pem from ti fae, after compile keywriter app, i have several questions:
1 which file should I use to burn:
2 How to flash the keywriter file when the system is not boot
3 How to control the voltage VPP_CORE and VPP_MCU when flashing the keywritter?
BRs,

Hi Xie,
Please open a new ticket for KeyWriter related queries. This is deviating from the original thread title.
Please look through the corresponding OTP KeyWriter documentation in the PDK Documentation of the RTOS SDK.
