With board revision 1.3, SolidRun moved the power LED to the middle of the board. In old place of power LED a GPIO controllable heartbeat LED was added. This commit touches only Single Shot variant, because all have revision 1.3. Some boards could be placed in an enclosure, therefore the LED18 is enabled by default, since that'll be the only visible indicator that the board is operating.

Subject: [PATCH] arm64: dts: mcbin-singleshot: add heartbeat LED
|
|
|
|
With board revision 1.3, SolidRun moved the power LED to the middle of
|
|
the board. In old place of power LED a GPIO controllable heartbeat LED
|
|
was added. This commit only touches Single Shot variant, since only this
|
|
variant is all revision 1.3.
|
|
|
|
Note:
|
|
This is slightly modified patch. Some boards could be placed in an
|
|
enclosure, so the LED18 is enabled by default, since that'll be the only
|
|
visible indicator that the board is operating.
