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 0xa000_0000 8 bit 256MB PAXE on CS3 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 Assuming you're using BASH shell: export CROSS_COMPILE=your-cross-compile-prefix cd u-boot make distclean make kmeter1_config make 4.
