Hi; This is not directly related to u-boot but I hope someone can enlighten me on this. The HRCW(BMS) defines the boot memory space to be either in 0xFE00_0000:0xFFFF_FFFF or 0:0x01FF_FFFF. I am new to this and I would like to find out if HRCW(BMS) is tightly coupled to the flash base and bootaddress defined in bdi2000 configuration file. If my board has 4 flash chips with 2MB per chip, should I have something like this with relation to HRCW(BMS)?
HRCW(BMS) = 0 to 0x01FF_FFFF: [TARGET] BOOTADDR = 0x100
[FLASH] erase 0 CHIP erase 0x200000 CHIP erase 0x400000 CHIP erase 0x800000 CHIP
uboot: TEXT_BASE = 0
versus:
HRCW(BMS) = 0xFE00_0000 to 0xFFFF_FFFF: [TARGET] BOOTADDR = 0xFFF00100
[FLASH] erase 0xFF800000 CHIP erase 0xFFA00000 CHIP erase 0xFFC00000 CHIP erase 0xFFE00000 CHIP
uboot: TEXT_BASE = 0xFFF0 0000
If I use the second configuration with BMS 0xFE00_0000:0xFFFF_FFFF, my u-boot image is loaded to the end of the flash region and the size of my u-boot image is limited to (0xFFFF_FFFF - 0xFFF0_0000 = 1MB) while if I use BMS 0x0:0x01FF_FFFF, the size of the u-boot is not limited? Thank you and appreciate any insight.
