boot up by tftpboot

I'm debugging the i.MX 8M Mini board.

Now I can compile the kernel and get Image file. I put the Image file to SD card to replace the old one, the board can boot up to linux smoothly.
Now I'd like to get Image in ubbot by tftpboot.

As far as I know, in uboot, I can use the following command to load Image to ram:
tftp <addr in ram> Image

But how to set the address in ddr?

Thanks!

Hi @mm2021,

Please read the Linux user guide, chapter 4.4.1.2 Downloading an image to MMC/SD, there you will find how to do the configuration and the steps to follow.

https://www.nxp.com/docs/en/user-guide/IMX_LINUX_USERS_GUIDE.pdf

For the loadaddr I think it is 0x40480000, also you could see this address if you, on U-boot write printenv and look for that address.

Hope this helps you.

Regards,

Israel.
