i2c device is not detecting in u-boot. while the same device is detected in linux when changed bus clock-frequency to 100 Mhz from 400 Mhz in dtb.

Why do you need to access the device in u-boot?
Could you probe to check if host send the access command from the bus.

I need to configure the device from i2c.

from jetson u-boot it is failing to list device after scan ( i2c probe ).
when used power-pc u-boot it is listing
OK please have probe the bus to check if any signal from the host bus to clarify the problem.
Hi shrinathchoudhary,
Is this still an issue? Any result can be shared?
