Freescale MPC8360EMDS Board ----------------------------------------- 1. Board Switches and Jumpers 1.0 There are four Dual-In-Line Packages(DIP) Switches on MPC8360EMDS 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 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. SW3[1:8]= 0000_0001 refers to bits labeled 1 through 6 is set as "On" and bits labeled 8 is set as "Off". 1.1 There are three type boards for MPC8360E silicon up to now, They are * MPC8360E-MDS-PB PROTO (a.k.a 8360SYS PROTOTYPE) * MPC8360E-MDS-PB PILOT (a.k.a 8360SYS PILOT) * MPC8360EA-MDS-PB PROTO (a.k.a 8360SYS2 PROTOTYPE) 1.2 For all the MPC8360EMDS 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]= 0000_0100 (HRCW setting value is performed on local bus) SW4[1-8]= 0011_0000 (Flash boot on local bus) SW9[1-8]= 0110_0110 (PCI Mode enabled. HRCW is read from FLASH) SW10[1-8]= 0000_1000 (core PLL setting) SW11[1-8]= 0000_0100 (SW11 is on the another side of the board) JP6 1-2 on board Oscillator: 66M 1.3 Since different board/chip rev. combinations have AC timing issues, u-boot forces RGMII-ID (RGMII with Internal Delay) mode on by default by the patch (mpc83xx: Disable G1TXCLK, G2TXCLK h/w buffers). When the rev2.x silicon mount on these boards, and if you are using u-boot version after this patch, to make the ethernet interfaces usable, and to enable RGMII-ID on your board, you have to setup the jumpers correctly. * MPC8360E-MDS-PB PROTO nothing to do * MPC8360E-MDS-PB PILOT JP9 and JP8 should be ON * MPC8360EA-MDS-PB PROTO JP2 and JP3 should be ON 2. Memory Map 2.1. The memory map should look pretty much like this: 0x0000_0000 0x7fff_ffff DDR 2G 0x8000_0000 0x8fff_ffff PCI MEM prefetch 256M 0x9000_0000 0x9fff_ffff PCI MEM non-prefetch 256M 0xc000_0000 0xdfff_ffff Empty 512M 0xe000_0000 0xe01f_ffff Int Mem Reg Space 2M 0xe020_0000 0xe02f_ffff Empty 1M 0xe030_0000 0xe03f_ffff PCI IO 1M 0xe040_0000 0xefff_ffff Empty 252M 0xf000_0000 0xf3ff_ffff Local Bus SDRAM 64M 0xf400_0000 0xf7ff_ffff Empty 64M 0xf800_0000 0xf800_7fff BCSR on CS1 32K 0xf800_8000 0xf800_ffff PIB CS4 32K 0xf801_0000 0xf801_7fff PIB CS5 32K 0xfe00_0000 0xfeff_ffff FLASH on CS0 16M 3. Definitions 3.1 Explanation of NEW definitions in: include/configs/MPC8360EMDS.h CONFIG_MPC83xx MPC83xx family for both MPC8349 and MPC8360 CONFIG_MPC8360 MPC8360 specific CONFIG_MPC8360EMDS MPC8360EMDS board specific 4. Compilation MPC8360EMDS shipped with 33.33MHz or 66MHz oscillator(check U41 chip). Assuming you're using BASH shell: export CROSS_COMPILE=your-cross-compile-prefix cd u-boot make distclean make MPC8360EMDS_XX_config make MPC8360EMDS support ATM, PCI in host and slave mode. To make u-boot support ATM : 1) Make MPC8360EMDS_XX_ATM_config To make u-boot support PCI host 66M : 1) DIP SW support PCI mode as described in Section 1.1. 2) Make MPC8360EMDS_XX_HOST_66_config To make u-boot support PCI host 33M : 1) DIP SW setting is similar as Section 1.1, except for SW3[4] is 1 2) Make MPC8360EMDS_XX_HOST_33_config To make u-boot support PCI slave 66M : 1) DIP SW setting is similar as Section 1.1, except for SW9[3] is 1 2) Make MPC8360EMDS_XX_SLAVE_config (where XX is: 33 - 33.33MHz oscillator 66 - 66MHz oscillator) 5. Downloading and Flashing Images 5.0 Download over serial line using Kermit: loadb [Drop to kermit: ^\c send <u-boot-bin-image> c ] Or via tftp: tftp 10000 u-boot.bin 5.1 Reflash U-boot Image using U-boot tftp 20000 u-boot.bin protect off fef00000 fef3ffff erase fef00000 fef3ffff cp.b 20000 fef00000 xxxx or cp.b 20000 fef00000 3ffff You have to supply the correct byte count with 'xxxx' from the TFTP result log. Maybe 3ffff will work too, that corresponds to the erased sectors. 6. Notes 1) The console baudrate for MPC8360EMDS is 115200bps.
