Re: [U-Boot] How to boot a newer version of u-boot from a older one?
hi, Could you tell me which configuration should I use? There are 4 configurations for MPC8313ERDB...
MPC8313ERDB_33 powerpc mpc83xx mpc8313erdb
freescale - MPC8313ERDB:SYS_33MHZ
MPC8313ERDB_66 powerpc mpc83xx mpc8313erdb
freescale - MPC8313ERDB:SYS_66MHZ
MPC8313ERDB_NAND_33 powerpc mpc83xx mpc8313erdb
freescale - MPC8313ERDB:SYS_33MHZ,NAND_U_BOOT
MPC8313ERDB_NAND_66 powerpc mpc83xx mpc8313erdb
freescale - MPC8313ERDB:SYS_66MHZ,NAND_U_BOOT

I am not sure of the correct make option though, but you must try flashing NAND flash with NAND boot loader and do experiments there. It would be good not to tamper with the existing NOR boot loader for now. => tftp 1000000 u-boot-nand.bin => nand erase 0 80000 => nand write 1000000 0 80000
Switch off the board. Change the switch settings to boot from NAND. And switch on the board.

hi there, I bought a Freescale MPC8313E-RDB some days before. The version of u-boot on that board is quite old and I wanna run a newer one. I have already built the latest git version of u-boot for that board. But I found there are several configuration files:
MPC8313ERDB_33 powerpc mpc83xx mpc8313erdb
freescale - MPC8313ERDB:SYS_33MHZ
MPC8313ERDB_66 powerpc mpc83xx mpc8313erdb
freescale - MPC8313ERDB:SYS_66MHZ
MPC8313ERDB_NAND_33 powerpc mpc83xx mpc8313erdb
freescale - MPC8313ERDB:SYS_33MHZ,NAND_U_BOOT
MPC8313ERDB_NAND_66 powerpc mpc83xx mpc8313erdb
freescale - MPC8313ERDB:SYS_66MHZ,NAND_U_BOOT
My board is Rev C and all switches are in factory default, could you tell me which configuration should I use?
For I have no USBTAP, there are no way for me to flush either NOR Flash or NAND Flash, so I am afraid if I install my u-boot to NOR Flash and that u-boot cannot run correctly, my board would be unavailable. So I wanna boot the latest version of u-boot from the original one. I tried these: => tftp 0x01000000 u-boot.bin => go 0x01000000
But my board reset automatically. Could you tell me how to do with this? Thanks.
