Hi,all
I'm new to U-boot.I am working on a MPC8247 board which has EEPROM(512KB) as the Boot chip and a flash(16MB) as the data flash.The physical address of the EEPROM is 0xfff80000-0xffffffff,and the physical address of the flash is 0xC2000000-0xC3000000.I have several questions as listed below:
1) If we could burn the u-boot.bin to the EEPROM throuth programer off the board and only read data from the EEPROM on board,should i need the driver for the EEPROM?
2) If it is correct to set the values of CFG_FLASH_BASE, CFG_MONITOR_BASE and TEXT_BASE like this: CFG_FLASH_BASE=0xC2000000 CFG_MONITOR_BASE=0xfff80000 TEXT_BASE=0xfff80000
3) I saw CFG_RAMBOOT in Start.S and CFG_LOWBOOT in MPC8260ads.h.What is the meaning of them,sorry I am blunt to software.
Any suggestion is appreciated!
Best Regards, levy
