Yes, this is correct. > But my ppc405GP walnut board has 512KB flash for holding u-boot. All Walnut boards have 512k of NOR FLASH. Do you really have an original IBM/AMCC Walnut or a different custom 405GP board? > I wonder > how to build a 512KB bin? Generally this is possible. You need to change CONFIG_MONITOR_LEN & CFG_MONITOR_BASE in include/configs/walnut.h. And TEXT_BASE in board/amcc/walnut/config.mk. > Is there any OPTION/SETTING targeting this > problem? Anything else > I should take care? But please don't forget that the environment is also stored in the NOR FLASH. And by changing the U-Boot size to 512k you leave no space for the environment. So why exactly do you want to change the U-Boot image size?
