UBOOT: How to detect all devices on TI8168 EVM through i2c

Angel Phillips

Hi everyone,

I have been trying to configure the peripheral devices on TI8168 EVM from uboot using i2c, but I don't get to detect some devices using i2c probe command, Also I have tried to read them, but it was failure.

Does anyone know something that I allow to show all devices on TI8168 EVM connected by i2c?

I am using u-boot-2010.06-psp04.04.00.01.

Best Regards

Angel.

I dont understand why i2c probe can not dectect some devices.
Could you provide the devices which is missing on your board? And I would like to have you log that what the i2c probe command returns.

Can you check on which i2c line your device is connected? it might be connected on different instance, in that case, you could change the i2c instance id on the uboot prompt and then probe it.
