Looks like ONLP library is looking for non-existing file. There is no file "psu_present" in a filesystem for both PSU1 and PSU2

cd /sys/bus/i2c/devices/11-005b/

Hi, could you simply check output of "onlpdump"?
I cannot replicate problem you mentioned on mine.
And the psu_present are under following location:
root@localhost:~# ls /sys/bus/i2c/devices/*/psu_present
/sys/bus/i2c/devices/10-0050/psu_present
/sys/bus/i2c/devices/11-0053/psu_present

from opennetworklinux.

I do not have onlpdump

onlpdump

-sh: onlpdump: not found

We have 2 AC power supplies.
/sys/bus/i2c/devices/10-0050/ and /sys/bus/i2c/devices/11-0053 are both empty:

Driver ym2651 puts PSU info into /sys/bus/i2c/devices/10-0058 and /sys/bus/i2c/devices/11-005b
there is no "psu_present" file in both.

I2C devices are instantiated boot time by shell script as follows:

initiate PSU-1

echo as7712_32x_psu 0x53 > /sys/bus/i2c/devices/i2c-11/new_device
echo ym2651 0x5b > /sys/bus/i2c/devices/i2c-11/new_device

initiate PSU-2

echo as7712_32x_psu 0x50 > /sys/bus/i2c/devices/i2c-10/new_device
echo ym2651 0x58 > /sys/bus/i2c/devices/i2c-10/new_device

Please confirm that this is correct.

Hi,

1. Model ids should be specified with index.
   echo as7712_32x_psu1 0x53 > /sys/bus/i2c/devices/i2c-11/new_device
   echo as7712_32x_psu2 0x50 > /sys/bus/i2c/devices/i2c-10/new_device

2. As replied, psu_present are not @/sys/bus/i2c/devices/10-0058 and /sys/bus/i2c/devices/11-005b.
   They are at /sys/bus/i2c/devices/10-0050/psu_present and /sys/bus/i2c/devices/11-0053/psu_present, respectively.

Besides, no onlp_psu_info_get() inside libonlp-x86-64-accton-as7712-32x.so.
If you want to call onlp_psu_info_get(), you should load libonlp.so.

nm /lib/platform-config/x86-64-accton-as5812-54x-r0/onl/lib/libonlp-x86-64-accton-as5812-54x.so
