Part Number: TDA4VM

Dear experts

I used tda4vm, I want to change the boot flow to

sbl(norflash) -> ATF-TEE (norflash) -> SPL (norflash) -> u-boot (norflash) -> kernel (eMMC).

Do I need to change the sdk code

Are they compiled the same way as the SD card boot version, and how to build them(sbl/atf-tee/spl/u-boot/kernel)?

Thanks.

Hi,

You can use the combined appimage for this. Please refer to the HLOS boot section in the document for details: https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/07_03_00_07/exports/docs/pdk_jacinto_07_03_00_29/docs/userguide/jacinto/boot/boot_k3.html#building-the-sbl-and-its-components

Thank you for your reply, I have one question,Please help.

https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/08_04_00_06/exports/docs/pdk_jacinto_08_04_00_21/docs/userguide/jacinto/boot/boot_k3.html#booting-via-ospi-flash

This website says, "Booting Via OSPI flash". Flash addresses for Images

tiboot3.bin (SBL) is flashed to address 0x0
<system_firmware_name>.bin (TIFS or SYSFW) is flashed to address 0x80000
<app_name>.appimage (APP) is flashed to address 0x100000
Optional: <xip_app>.bin (XIP.bin) is flashed to 0x1C0000
OSPI PHY tuning data binary must also be flashed to the start of the last flash sector (e.g., usually a 512kB or 256kB size sector)

My question is, What's the address should I put the u-boot, or put it in emmc?

Hi,

I have not tried using development boot flow with the OSPI.

Can you try flashing u-boot at address at 0x280000 and see if it works?

Hi,

Well, I'll try that, Thank you.

Are these addresses fixed, Can it be modified?

Hi,

The address for tiboot3.bin is fixed as it is where ROM looks for the SBL. The offset for the tifs and the application can be modified from the SBL itself.
