TS-8551-jumpers
From embeddedTS Manuals
The TS-8551 has a block of jumpers located near the rear of the PCB. These jumpers control a number of aspects of the platform's behavior. The jumpers are labeled on the silkscreen rather than numbered:
| Label | Description |
|---|---|
| SD Boot | When jumper is set, boot kernel and Os from the SD card. Otherwise boot kernel and OS from eMMC. |
| No Charge | When jumper is set, disable charging of the TS-SILO Supercapacitors. Beneficial for early development and testing. |
| U-Boot | When jumper is set, U-Boot attempts to boot from USB before dropping to a U-Boot shell. Otherwise boot straight to Debian. |
| TS-4400 | Required to support booting a TS-4400 on the TS-8551. This should be left open when the TS-8551 is used with a SoM other than the TS-4400. |
| SBC 5V On | Used for internal engineering/development. This should be left open. |
