TS-7600 LEDs
From embeddedTS Manuals
On all of our baseboards we include 2 indicator LEDs which are under software control. You can manipulate these using "tshwctl --greenledon --redledon" or "tshwctl --greenledoff --redledoff". The LEDs have 4 behaviors from default software.
Green Behavior | Red behavior | Meaning |
---|---|---|
Solid On | Off | System is booted and running |
Solid On | On for approximately 15s, then off | Once the system has booted the kernel and executed the startup script, it will check for a USB device and then determine if it is a mass storage device. This is used for updates/blasting through USB. Once it determines this is not a mass storage device the red LED will turn back off. |
On for 10s, off for 100ms, and repeating | Turns on after Green turns off for 300ms, and then turns off for 10s | The watchdog is continuously resetting the board. This happens when the system cannot find a valid boot device, or the watchdog is otherwise not being fed. This is normally fed by tshwctl once a valid boot media has started. See the #Watchdog section for more details. |
Off | Off | The FPGA is not able to start. Typically either the board is not being supplied with enough voltage, or the FPGA has been otherwise damaged. If a stable 5 V is being provided and the supply is capable of providing at least 1 A to the device, an RMA is suggested. |
Blinking about 5ms on, about 10ms off. | Blinking about 5ms on, about 10ms off. | The board is receiving too little power, or something is drawing too much current from the device's power rails. |
