TS-8150-47XX Jumpers

The TS-8150 includes a header with several jumpers and signals:

Jumper Description SD Boot Used for bootstrapping the System-on-Module (SoM) to boot to SD En Con Enables the Console by replacing XUART1 with the CPU console ttyS0 I2C (top) Connects I2C CLK to the #DIO Header I2C (bottom) Connects I2C DAT to the #DIO Header JP6 Connected to MFP_42

You can read JP6 with:

echo $(($(devmem 0xd4019004 32) >> 10 & 0x1))

This will return 0 when the jumper is on, and 1 when the jumper is off.
