hi,all! I use the i2c-tools-3.0.1 tool to compile and install in DM355 EVM
kernel, For example with orders #i2cdetect 0, prompts following information:
WARNING! This program can confuse your I2C bus, cause data loss and worse!I
will probe file /dev/i2c/0.I will probe address range 0x03-0x77.Continue?
[Y/n]Then the basis bus address range 0x03-0x07,orders the test with below:
#i2cdump 0 0x03-0x77, only 0x5D and 0x1B two bus addresses are effective, For
example # i2cdump 0 0x5dprompt the information to be as follows:No size
specified (using byte-data access)Error: Could not set address to 0x5d: Device
or resource busy Other bus address is invalid, For example : # i2cdump 0
0x3aprompts the information to be as follows: No size specified (using
byte-data access) WARNING! This program can confuse your I2C bus, cause data
loss and worse!I will probe file /dev/i2c/0, address 0x3a, mode byteContinue?
[Y/n]
Whether only 0x5D and the 0xB1 two device address hang on the I2C bus ???
First time with this tool software, everybody help explained in detail!
thanks everybody!
