Rebuilding the bootloader

6.1

XLoader

The default XLoader provided as pre-flashed on all SPEAr evaluation boards, as well as

binary image on ST Web site for upgrades, is built for serial NOR Flash.

If needed, the XLoader firmware image has to be rebuilt taking into account each specific

embedded MPU and memory types. Therefore, there are many cases and relevant

commands to be run on Linux PC, as described below.

EVALSPEAR300

$ make clean

$ make SOC=SPR300 DDRFREQ=333 DDRSIZE=128M

$ cp obj/xloader_image.bin

./../Flash/xloader/xloader_s300_333DDR.uimg

EVALSPEAR310

$ make clean

$ make SOC=SPR310 DDRFREQ=333 DDRSIZE=128M

$ cp obj/xloader_image.bin

../../Flash/xloader/xloader_s310_333DDR.uimg

EVALSPEAR320PLC

$ make clean

$ make SOC=SPR320 DDRFREQ=333 DDRSIZE=128M

$ cp obj/xloader_image.bin

../../Flash/xloader/xloader_s320_333DDR.uimg

EVALSPEAR600

$ make clean

$ make SOC=SPR600

DDRFREQ=333 DDRSIZE=128M

$ cp obj/xloader_image.bin

../../Flash/xloader/xloader_s600_333DDR_128M.uimg

6.2

U-Boot

The default U-Boot provided as pre-flashed on all SPEAr evaluation boards, as well as

binary image on ST Web site for upgrades, is built for serial NOR Flash.

If needed, the U-Boot firmware image has to be rebuilt taking into account each specific

embedded MPU and Flash memory type. Therefore, there are many cases and relevant

commands as described below.
