I2c burst read may failed due to misoperation of ir3570a(A DC-to-DC converter IC). As #2966, there are 3 more models have this symptom, as7326-56x, as7726-32x, and as9716-32d. Also correct typo of naming on as7816-64x and as7716-32x. Signed-off-by: roy_lee roy_lee@accton.com What I did Disabling i2c function of ir3570a which may failed i2c tranfer to others. Close channel of mux after data transfered. How I did it Identify version of ir3570, if it's ir3570a, disable its alias i2c address. Enable parameter of driver i2c_mux_pca954x to close channel on after every access. How to verify it Write 08 to offset 0xcf of systom eeprom and execute i2c block read. It will return error. plug-in several transceivers and run "show interfaces transceiver presence" and "sfputil show presence". You may see the different result. (But doing this requires updated xcvrd). Signed-off-by: roy_lee <roy_lee@accton.com> |

To initialize the system, run "accton_as7712_util.py install". To clean up the drivers & devices, run "accton_as7712_util.py clean". To dump information of sensors, run "accton_as7712_util.py show". To dump SFP EEPROM, run "accton_as7712_util.py sff". To set fan speed, run "accton_as7712_util.py set fan". To enable/disable SFP emission, run "accton_as7712_util.py set sfp". To set system LEDs' color, run "accton_as7712_util.py set led" For more information, run "accton_as7712_util.py --help". ==================================================================== Besides applying accton_as7712_util.py to access peripherals, you can access peripherals by sysfs nodes directly after the installation is run. LED controls can be found under /sys/class/leds. The sysfs interface color mappings are as follows: Brightness: 0 => off 1 => green 2 => amber 3 => red 4 => blue There are 5 system LEDs, loc, diag, fan, ps1, and ps2. They are lit automatically by CPLD, but the loc and diag. The loc led has only 1 color, blue. The diag one has 3 colors: red, amber, and green. Fan controls can be found in /sys/bus/i2c/devices/2-0066. There are 12 fans inside 6 fan modules. All fans share 1 duty setting, ranged from 0~100. Three temperature sensors are controlled by the lm75 kernel modules. They should already be visible under /sys/bus/i2c/drivers/lm75/. Two power supplies are controlled by the CPLD. Here provide their status under /sys/bus/i2c/devices/10-0050 and /sys/bus/i2c/devices/11-0053. There are 32 QSFP+ modules are equipped. Apply "accton_as7712_util.py show" to get their status. Apply "accton_as7712_util.py set sfp" to turn on/off light transmission. Apply "accton_as7712_util.py sff" to dump EEPROM information. Before operating on that QSFP+, please make sure it is well plugged. Otherwise, operation is going to fail.
