Recently I installed linux on my asustor NAS on an m.2 (Rocky 8, Asustor AS6704T). lcm worked perfect for managing the display, but there is also a green LED that continuously blinks now. Normally it would just blink until ADM started at which time I guess it would take over and then use the LED for various outputs. This is not the disk activity LED (on the front bottom left) but below the blue power LED on the front top left.
Any idea how I could go about finding out if this is controlled via the same serial interface and how to control it?
dmesg shows two serial interfaces:
[ 1.050440] 00:03: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A
[ 1.071230] 00:04: ttyS1 at I/O 0x2f8 (irq = 3, base_baud = 115200) is a 16550A
/dev/ttyS1 appears to be the tty for managing the LCD so I don't know if it is possible that ttyS0 is for the LED(s)?
