Toolchain - - The Binutils in current ELDK toolchain will not support MPC85xx - chip. You need to use binutils-2.14.tar.bz2 (or newer) from - http://ftp.gnu.org/gnu/binutils. - - The 8540/8560 ADS code base is known to compile using: - gcc (GCC) 3.2.2 20030217 (Yellow Dog Linux 3.0 3.2.2-2a) - - -1. SWITCH SETTINGS & JUMPERS - -1.0 Nomenclature - - 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" (unlabeled) is logic 1. - Luckily, we're SW types and virtual settings are handled daily. - - The switches for the Rev A board are numbered differently than - for the Pilot board. Oh yeah. - - 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 - - SW18 is switch 18 as silk-screened onto the board. - 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 - SW3[7:1] refers to bits labeled 7 through 1 in order on switch 3 - -1.1 For the MPC85xxADS Pilot Board - - First, make sure the board default setting is consistent with the document - shipped with your board. Then apply the following changes: - SW3[1-6]="all OFF" (boot from 32bit flash, no boot sequence is used) - SW10[2-6]="all OFF" (turn on CPM SCC for serial port,works for 8540/8560) - SW11[2]='OFF for 8560, ON for 8540' (toggle 8540.8560 mode) - SW11[7]='ON' (rev2), 'OFF' (rev1) - SW4[7-8]="OFF OFF" (enable serial ports,I'm using the top serial connector) - SW22[1-4]="OFF OFF ON OFF" - SW5[1-10[="ON ON OFF OFF OFF OFF OFF OFF OFF OFF" - J1 = "Enable Prog" (Make sure your flash is programmable for development) - - If you want to test PCI functionality with a 33Mhz PCI card, you will - have to change the system clock from the default 66Mhz to 33Mhz by - setting SW15[1]="OFF" and SW17[8]="OFF". After that you may also need - double your platform clock(SW6) because the system clock is now only - half of its original value. For example, if at 66MHz your system - clock showed SW6[0:1] = 01, then at 33MHz SW6[0:1] it should be 10. - - SW17[8] ------+ SW6 - SW15[1] ----+ | [0:1] - V V V V - 33MHz 1 1 1 0 - 66MHz 0 0 0 1 - - Hmmm...

The one with - the RIO connector), you need to set SW1[4] (config) to 1 (off). - Also, configure the board to run PCI at 66 MHz. - -2. MEMORY MAP TO WORK WITH LINUX KERNEL - -2.1.

You - can download them from linuxppc-2.4 public source. Please make sure the - kernel's ppcboot.h is consistent with U-Boot's u-boot.h.
