RedBoot uses the serial port. The default serial port settings are 38400,8,N,1.
Management of onboard flash is also supported. Two basic RedBoot configurations are supported:
RedBoot running from RAM with RedBoot in the flash boot sector.
RedBoot running from the board's flash boot sector.
Program the ROM RedBoot image into flash using an eprom programmer.
RedBoot sets up the following memory map on the EDK7708 board.
Physical Address Range Description ----------------------- ----------- 0x80000000 - 0x8001ffff Flash (AT29LV1024) 0x88000000 - 0x881fffff DRAM 0xa4000000 - 0xa40000ff LED ON 0xb8000000 - 0xb80000ff LED ON |
These shell variables provide the platform-specific information needed for building RedBoot according to the procedure described in Chapter 30:
export TARGET=edk7708 export ARCH_DIR=sh export PLATFORM_DIR=edk7708 |
The names of configuration files are listed above with the description of the associated modes.
