The late Sonic building scripts, pushed @Dec 5 2016, will automatically
|
||
|
|
create a docker container and run building process under it.
|
||
|
|
User is not necessary to handle docker environment creation.
|
||
|
|
|
||
|
|

|
||
|
|
3. Build installer
|
||
|
|
- Change directory back to sonic-buildimage/.
|
||
|
|
- Get onie_installer-accton-AS7312-54X.patch" from patch/installer.
|
||
|
|
- Change setting for AS7312-54X by patching build_image.sh.
|
||
|
|
"patch -p1 < onie_installer-accton-AS7312-54X.patch"
|
||
|
|
!!NOTICE, patching onie_installer-accton-AS7312-54X.patch comments out the
|
||
|
|
"git status" checking at build_image.sh.
|
||
|
|
- The account and password of installed OS can be given at rules/config.
|
||
|
|
The default user and password are "admin" & "YourPaSsWoRd" respectively.
|
||
|
|
- Run "make configure PLATFORM=broadcom"
|
||
|
|
- Copy the built kernel debian package to target/debs/.
|
||
|
|
The file is linux-image-3.16.0-5-amd64_*_amd64.deb under directory
|
||
|
|
src/sonic-linux-kernel/.
|
||
|
|
- Run "make target/sonic-generic.bin"
|
||
|
|
- Get the installer, target/sonic-generic.bin, to target machine and install.

The code for integacting with Accton AS7312-54X has 2 parts,
|
||
|
|
kernel drivers and operational script.
|
||
|
|
The kernel drivers of peripherals are under module/ directory.
|
||
|
|
1. These drivers are patched into kernel by
|
||
|
|
driver-patches-for-accton-as7312-fan-psu-cpld.patch
|
||
|
|
Or you can build the driver under module/ by setting environment variable,
|
||
|
|
KERNEL_SRC, to proper linux built directory and run make.
|
||
|
|
It may be sonic-linux-kernel/linux-3.*/debian/build/build_amd64_none_amd64/.
|
||
|
|
2. A operational script, accton_as7312_util.py, for device initializatian and
|
||
|
|
peripheral accessing should be installed at /usr/bin.
|
||
|
|
This script is generated by onie_installer-accton-AS7312-54X.patch.
|
||
|
|
It's done by patching onie_installer-accton-AS7312-54X.patch at build-image.
|
||
|
|
Run "accton_as7312_util.py install" to install drivers.
|
||
|
|
|
||
|
|
To initialize the system, run "accton_as7312_util.py install".
|
||
|
|
To clean up the drivers & devices, run "accton_as7312_util.py clean".
|
||
|
|
To dump information of sensors, run "accton_as7312_util.py show".
|
||
|
|
To dump SFP EEPROM, run "accton_as7312_util.py sff".
|
||
|
|
To set fan speed, run "accton_as7312_util.py set fan".
|
||
|
|
To enable/disable SFP emission, run "accton_as7312_util.py set sfp".
|
||
|
|
To set system LEDs' color, run "accton_as7312_util.py set led"
|
||
|
|
For more information, run "accton_as7312_util.py --help".
|
||
|
|
|
||
|
|
====================================================================
|
||
|
|
Besides applying accton_as7312_util.py to access peripherals, you can
|
||
|
|
access peripherals by sysfs nodes directly after the installation is run.
|
||
|
|
|
||
|
|
System LED:
|
||
|
|
There are 5 system LEDs at the lower-left corner of front panel.
|
||
|
|
They are loc, diag, fan, ps1, and ps2.
|
||
|
|
The sysfs interface color mappings are as follows:
|
||
|
|
Brightness:
|
||
|
|
0 => off
|
||
|
|
1 => green
|
||
|
|
2 => amber
|
||
|
|
3 => red
|
||
|
|
4 => blue
|
||
|
|
But not all colors are available for each LED.
|
||
|
|
|
||
|
|
Fan Control:
|
||
|
|
There are 10 fans inside 5 fan modules.
|
||
|
|
All fans share 1 duty setting, ranged from 0~100.
|
||
|
|
|
||
|
|
Thermal sensers:
|
||
|
|
3 temperature sensors are controlled by the lm75 kernel modules.
|
||
|
|
|
||
|
|
PSUs:
|
||
|
|
There 2 power supplies slot at the left/right side of the back.
|
||
|
|
Once if a PSU is not plugged, the status of it is shown failed.
|
||
|
|
|
||
|
|
There are 48 SFP+ and 6 QSFP modules are equipped.
|
||
|
|
Before operating on PSU and QSFP+, please make sure it is well plugged.
|
||
|
|
Otherwise, operation is going to fail.
