Need to Get into BIOS

Rushil3006 — Wed, 08 Nov 2023 06:12:28 GMT

I've been trying to get into the BIOS in the i.MX93EVK to try and enable fTPM before the Windows 10 IoT OS boots up but with no success. Continuously tapping the ESC or DEL key takes it to the Windows recovery mode chain. I even tried to access UEFI firmware settings through Advanced settings in Windows recovery mode...but restarting it doesn't load the BIOS GUI at all.

Need some help with this...Thanks

Hello,

The U-Boot proper is used in this project to perform early display initialization and load the UEFI bootloader. You just need to apply a click on your keyboard to enter to its configuration.

Could you please let me the know the exact U-Boot setting to be changed or the key to be clicked to get into the UEFI bootloader?

Thanks

Hi @Rushil3006,

in order to enable fTPM is it necessary to build secured (signed_firmware.bin) firmware with the following parameters:

buildme64.sh -b <board-type> -t all -t secured_efi -nu

Then you can check functionality in the Device Manager -> System devices -> Microsoft Windows Trusted Runtime Secure Service. Driver should working correctly.

Best regards,

Michal
