It is +manufactured by EETS GmbH (https://www.eets.ch). The core of the board is a m2 +SOM from bytes at work (https://www.bytesatwork.ch) which in turn is based on +AM3352 SOC from TI (http://www.ti.com). + +Customization +============= + +As usual the console serial interface is set by CONFIG_CONS_INDEX. Best choice +is 4 here since UART3 is wired to the connector K2. +The Run LED on the PDU-001 can be turned on red by setting CONFIG_RUN_LED_RED +or green by setting CONFIG_RUN_LED_GREEN. Setting CONFIG_RUN_LED_OFF will turn +off the Run LED. + +Booting +======= + +The system boots from either eMMC or SD card cage. It will first try to boot +from the SD card cage. If this fails (missing or unbootable SD card) it will +try to boot from the internal eMMC. The root file system is always expected to +be located in the second partition of the device (eMMC or SD card) that pro- +vided the boot loader. |
