7 * As upstream Linux does not support XIP, it cannot run in 8 MiB of HyperRAM.
8 * Hence the 64 MiB of SDRAM on the sub-board needs to be enabled, which has
9 * the following ramifications:
10 * - SCIF4 connected to the on-board USB-serial can no longer be used as the
11 * serial console,
12 * - Instead, SCIF2 is used as the serial console, by connecting a 3.3V TTL
13 * USB-to-Serial adapter to the CMOS camera connector:
14 * - RXD = CN17-9,
15 * - TXD = CN17-10,
16 * - GND = CN17-2 or CN17-17,
17 * - The first Ethernet channel can no longer be used,
18 * - USB Channel 1 loses the overcurrent input signal.
19 *
20 * Please make sure your sub-board matches the following switch settings:
21 *
22 * SW6 SW6-1 set to SDRAM
23 * ON SW6-2 set to Audio
24 * +---------------------+ SW6-3 set to DRP
25 * | = = = = = | SW6-4 set to CEU
