How to use i2c-tools on dragonboard 410c debian system


#1

HI,
I flash dragonboard with the last debian system. you see check you system version:
linaro@linaro-alip:~$ cat /proc/version
Linux version 4.2.4-linaro-lt-qcom (buildslave@x86-64-07) (gcc version 4.9.2 20140904 (prerelease) (crosstool-NG linaro-1.13.1-4.9-2014.09 - Linaro GCC 4.9-2014.09) ) #1 SMP PREEMPT Fri Dec 4 12:42:30 UTC 2015
linaro@linaro-alip:~$
and I apt-get install i2c-tools.and check the i2c device:
root@linaro-alip:~# i2cdetect -y -r 0
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: – -- – -- – -- – -- – -- – -- –
10:
the i2cdetect works unusually. and the kernel put:

[ 1624.313521] i2c_qup 78b6000.i2c: timeout for fifo not empty
[ 1640.163959] i2c_qup 78b6000.i2c: timeout for fifo not empty

[ 1735.266047] i2c_qup 78b6000.i2c: NACK from c

is the last debian kernel image driver fine ? or what’s should I do ?
