Hi,
When I try to access a switch using the I2C bus from the BMC controller. I have got this error.
the switch address is 0x56
and i2c bus is 2
# i2c-test -b 0x02 -s 0x56 -r -rc 1
i2c-test -b 2 -s 0x56 -r -rc 1
FAILED Read: -2147483517
errno is 121
Failure on single read: Remote I/O error
Error on operation
why the error is shown like this. what that means.
Note : sometimes the switch get able to access.
Please give me a solution.
