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.

hi,
Could you tell me which configuration should I use? There are 4 configurations for MPC8313ERDB...

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.

This doesn't work. See the explanation in the FAQ:

MPC8313ERDB_33 is for booting from NOR, which is the default.

The "66" targets are for an earlier version of the board that had a 66MHz crystal rather than 33MHz.

Your best option is probably to build MPC8313ERDB_NAND_33, and put it in NAND flash. Then you can change the board switches to boot from NAND, and if it doesn't work, switch them back to NOR which you've left unmodified.

Once you have a working NAND, you can replace the NOR image, switching back to NAND if the new NOR image is broken.

And of course be careful not to write to the wrong flash, and destroy your backup boot source.

Thanks for your help. Now I have already wrote the newer version of u-boot into NAND Flash and boot from it!
Do you mind me to ask some more questions?
Where is environment stored? If I save the NAND-version u-boot's environment, will it overwrite the one of NOR-version u-boot?

Thanks.

Typically, when booting from NAND u-boot is configured to save the environment to NAND. You can always type 'save' and usually u-boot will print a message showing where the environment is saved. Double check the CONFIG*ENV* defines in your u-boot config file.
