Hi,all

When I use boot_mode 00 and Mfgtools tools whith commond

<CMD state="BootStrap" type="boot" body="BootStrap" file ="firmware/u-boot-imx7d%7duboot%_sd.imx" ifdev="MX7D">Loading U-boot</CMD>
<CMD state="BootStrap" type="jump" > Jumping to OS image. </CMD>

But uart no output information.

Then I change boot_mode 10 to boot from emmc(imx7d can boot from emmc before do mode 00),

the uart no output information too.

So, the imx7d boot_mode 00 make it damage?

Hello Peter Pan,

Would you please provide more details on what board you are using, the BSP release and the manufacturing tool script?

The boot mode 00 of the processor sets the boot from the processors fuses.

Boot mode 10 is set to boot from GPIOs boot configuration (unless the BT_FUSE_SEl is set to one). If this configuration is no longer working it may be that the GPIO boot configuration is not correct or that the eMMC image was damaged or something was written to it with the manufacturing tool, which is why is important to know the script used when executing the manufacturing tool.

I hope this helps!

Regards,
