Board Switches and Jumpers -1.0 There are four Dual-In-Line Packages(DIP) Switches on MPC837xEMDS board - For some reason, the HW designers describe the switch settings - in terms of 0 and 1, and then map that to physical switches where - the label "On" refers to logic 0 and "Off" is logic 1. - - Switch bits are numbered 1 through, like, 4 6 8 or 10, but the - bits may contribute to signals that are numbered based at 0, - and some of those signals may be high-bit-number-0 too. Heed - well the names and labels and do not get confused. - - "Off" == 1 - "On" == 0 - - SW4[8] is the bit labeled 8 on Switch 4. - SW2[1:6] refers to bits labeled 1 through 6 in order on switch 2. - SW2[1:8]= 0000_0001 refers to bits labeled 1 through 7 is set as "On" - and bits labeled 8 is set as "Off". - -1.1 For the MPC837xEMDS Processor Board - - First, make sure the board default setting is consistent with the - document shipped with your board. Then apply the following setting: - SW3[1-8]= 0011_0000 (BOOTSEQ, ROMLOC setting) - SW4[1-8]= 0000_0110 (core PLL setting) - SW5[1-8]= 1001_1000 (system PLL, boot up from low end of flash) - SW6[1-8]= 0000_1000 (HRCW is read from NOR FLASH) - SW7[1-8]= 0110_1101 (TSEC1/2 interface setting - RGMII) - J3 2-3, TSEC1 LVDD1 with 2.5V - J6 2-3, TSEC2 LVDD2 with 2.5V - J9 2-3, CLKIN from osc on board - J10 removed, CS0 connect to NOR flash; when mounted, CS0 connect to NAND - J11 removed, Hardware Reset Configuration Word load from FLASH(NOR or NAND) - mounted, HRCW load from BCSR. - - on board Oscillator: 66M - -2.
