LED not Blinking

LED not Blinking

Hi all,

We have a board containing BMC Aspeed AST-2500. One LED is connected to
GPIO-E0. I am using zaius machine configuration for building the image. I
want that LED to blink after BMC is booted. So I changed the following
files.

Patched the device tree file aspeed-bmc-opp-zaius.dts

 leds {
            compatible = "gpio-leds";
+        power {
+            gpios = <&gpio ASPEED_GPIO(E, 0) GPIO_ACTIVE_LOW>;
+        };
  };


Added the following configuration to sensor inventory file
openbmc/meta-ingrasys/meta-zaius/recipes-phosphor/ipmi/phosphor-ipmi-sensor-inventory%/config.yaml

bmc_booted:
    power:
        Action: 'Blink'
        DutyOn: 50
        Period: 1000
        Priority: 'On'

The LED is glowing when the BMC boots up. But it is not blinking. Please
someone help to resolve the issue.

Thanks in advance.

Hi,

The LEDs are defined in a different file, check out, for example,
meta-ibm/meta-romulus/recipes-phosphor/leds/romulus-led-manager-config/led.yaml.


You can tell it should be working when you see a
/xyz/openbmc_project/led/groups/bmc_booted  object on D-Bus.

I am using zaius machine configuration. In that led.yaml file is not
available.

You can add support for that using the guide at
https://github.com/openbmc/docs/blob/master/LED-architecture.md,
and also the Romulus layer has examples.

You would need to put this in led.yaml and that would get compiled into 
phosphor-led-manager as led-gen.hpp. Please see this as an example.

https://github.com/openbmc/openbmc/blob/master/meta-ibm/meta-romulus/recipes-phosphor/leds/romulus-led-manager-config/led.yaml

The LED is glowing when the BMC boots up. But it is not blinking. Please 
someone help to resolve the issue.
Thanks in advance.
