+Keymile kmeter1 Board
+-----------------------------------------
+1. Alternative Boot EEPROM
+
+ Upon the kmeter1 startup the I2C_1 controller is used to fetch the boot
+ configuration from a serial EEPROM. During the development and debugging
+ phase it might be helpful to apply an alternative boot configuration in
+ a simple way. Therefore it is an alternative boot eeprom on the PIGGY,
+ which can be activated by setting the "ST" jumper on the PIGGY board.
+
+2. Memory Map
+
+ BaseAddr PortSz Size Device
+ ----------- ------ ----- ------
+ 0x0000_0000 64 bit 256MB DDR
+ 0x8000_0000 8 bit 256KB GPIO/PIGGY on CS1

+ 0xe000_0000 2MB Int Mem Reg Space
+ 0xf000_0000 16 bit 256MB FLASH on CS0
+
+
+ DDR-SDRAM:
+ The current realization is made with four 16-bits memory devices.
+ Mounting options have been foreseen for device architectures from
+ 4Mx16 to 512Mx16. The kmeter1 is equipped with four 32Mx16 devices
+ thus resulting in a total capacity of 256MBytes.
+
+3. Compilation

+Sheldon Instruments SIMPC8313 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
+ | * * **** |
+ | * * |
+ +----------+
+ 12345678
+
+ To boot the image in Small page NAND flash, use these DIP
+ 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
+ 0xff00_0000 0xff00_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,
+ if the new u-boot doesn't boot, you can plug the board into
+ your PCI slot and with the supplied driver and sample app
+ you can reburn a working u-boot.
+
+4.2 Downloading and Booting Linux Kernel
+
+ Ensure that all networking-related environment variables are set
+ properly (including ipaddr, serverip, gatewayip (if needed),
+ netmask, ethaddr, eth1addr, fdtfile, and bootfile).
+
+ =>tftp $loadaddr uImage
+ =>nand write $loadaddr kernel $filesize
+ =>tftp $loadaddr $fdtfile
+ =>nand write $loadaddr 7e0000 1800
+
+ =>boot
+
+5 Notes
+
+ The console baudrate for SIMPC8313 is 115200bps.
