+Freescale MPC8313ERDB Board
+-------------------------------------------------------------------------------
+
+1.	Board Switches and Jumpers
+
+	S2 is used to set CFG_RESET_SOURCE.
+
+	To boot the image in Large page NAND flash, use

these DIP
+ switch settings for S2:
+
+ +----------+ ON

+	| * * **** |
+	|  * *     |

+ switch settings for S2:
+
+ +----------+ ON

+	| *** **** |

+ +----------+
+ 12345678
+ (where the '*' indicates the position of the tab of
the switch.)
+
+2. Memory Map
+ The memory map looks like this:
+
+ 0x0000_0000 0x1fff_ffff DDR 512M
+ 0x8000_0000 0x8fff_ffff PCI MEM 256M
+ 0x9000_0000 0x9fff_ffff PCI_MMIO 256M
+ 0xe000_0000 0xe00f_ffff IMMR 1M
+ 0xe200_0000 0xe20f_ffff PCI IO 16M
+ 0xe280_0000 0xe280_7fff NAND FLASH (CS0) 32K
+ or
+ 0xe280_0000 0xe281_ffff NAND FLASH (CS0) 128K
+ 0xfa00_0000 0xfa00_7fff FPGA (CS1) 1M
+
+3. Compilation
+
+ Assuming you're using BASH (or similar) as your
shell:
+
+ export CROSS_COMPILE=your-cross-compiler-prefix-
+ make distclean
+ make SIMPC8313_LP_config
+ (or make SIMPC8313_SP_config, depending on the page
size
+ of your NAND flash)
+ make
+
+4. Downloading and Flashing Images
+
+4.1 Reflash U-boot Image using U-boot
+
+ =>run update_uboot
+
+ You may want to try
+ =>tftp $loadaddr $uboot
+ first, to make sure that the TFTP load will succeed
before it
+ goes ahead and wipes out your current firmware. And
of course,
+ have an alternate means of programming the flash
available
+ if the new u-boot doesn't boot.
+
+4.2 Downloading and Booting Linux Kernel
+
+ TODO:
+
+5 Notes
+
+ The console baudrate for SIMPC8313 is 115200bps.

1.5.5.1

It is. I'll change that.

Thank you,
