Part Number: TDA4VM-Q1
Other Parts Discussed in Thread: TDA4VM

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？

Regards,

Tahm

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？

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.
