Hi Gurus,
I am designing the BSP for our customized Router motherboard based on MPC8248.
I am currently referring to the MPC8272ADS BSP for the same.
It seems TEXT_BASE in u-boot-1.1.1\board\mpc8260ads\config.mk could be used to program HRCW with U-Boot by specifying it to be 0xfe000000 instead of 0xfe700000.
Hence I would have to program u-boot.bin at 0xfe000000 using the Flash programmer, by doing this MPC8272/48 could load the HRCW from NOR Flash.
Queries:
Do I also have to program another u-boot.bin with TEXT_BASE as 0xfe700000 to the NOR Flash as U-boot is supposed to be at 0xfe700000 & not 0xfe000000, Kindly substantiate your reply with an adress map for NOR Flash in MPC8272ADS board(comprising HRCW, JFFS, Kernel, U-boot, System exception vector, U-boot env. variables).
I understand the system exception vector shall be read by MPC8272 from 0xFFF00100 which shall be same as 0xFE700100 for a 8 MB NOR Flash & that it is also a part of U-Boot (Start.S). Kindly confirm.
