1 Freescale MPC837xEMDS Board
2 -----------------------------------------
3 1. Board Switches and Jumpers
4 1.0 There are four Dual-In-Line Packages(DIP) Switches on MPC837xEMDS board
11 and some of those signals may be high-bit-number-0 too. Heed
18 SW2[1:6] refers to bits labeled 1 through 6 in order on switch 2.
22 1.1 For the MPC837xEMDS Processor Board
24 First, make sure the board default setting is consistent with the
25 document shipped with your board. Then apply the following setting:
26 SW3[1-8]= 0011_0000 (BOOTSEQ, ROMLOC setting)
27 SW4[1-8]= 0000_0110 (core PLL setting)
28 SW5[1-8]= 1001_1000 (system PLL, boot up from low end of flash)
29 SW6[1-8]= 0000_1000 (HRCW is read from NOR FLASH)
30 SW7[1-8]= 0110_1101 (TSEC1/2 interface setting - RGMII)
31 J3 2-3, TSEC1 LVDD1 with 2.5V
32 J6 2-3, TSEC2 LVDD2 with 2.5V
33 J9 2-3, CLKIN from osc on board
38 on board Oscillator: 66M
