But if I do in Linux it work

Hi @WolsYang , which imx93 linux BSP are you using?

Do you not see any nodes inside this directory :-

/sys/devices/platform

please paste the output of "ls /sys/devices/platform/"
 

[gaurav_sharma]

And if you want to boot cm33 binary at Uboot, you have to additionally do the following after copying the image to TCM[i.e the step in which you execute "cp.b"]: -

bootaux 0x1ffe0000 0

[WolsYang]

I am working on 6.12

Boot m33 in u-boot by this cmd is work

bootaux 0x1ffe0000 0

But boot in Linux is still fail(Well it should be, we didn't change any thing)
