CW download uboot failed

威杨 — Tue, 01 Sep 2015 04:09:22 GMT

Dear all

I am new to CW, at present i use 10.4.0 .I use it download uboot. but always failed .

I want to use boot from nandflash , i modify ${ProjDirPath}/CFG/8309SOM_init_core.tcl

# CS0 - 8MB NOR FLASH

# BR0 base address at 0xff800000, port size 16 bit, GPCM, valid

mem [IMMR 0x5008] = 0xff801001

# OR0 8MB flash size, 15 w.s., timing relaxed

#writemem.l 0xe0005004 0xff806ff7

mem [IMMR 0x500c] = 0xff806ff7

# CS1 - NAND Flash 32 KB

# BR1 base address at 0xF0000000, port size 8 bit, FCM, valid

mem [IMMR 0x5000] = 0xf0000c21

# OR1 32KB size

#writemem.l 0xe000500c 0xFFFF8796

mem [IMMR 0x5004] = 0xFFFF8796

# CS0 - 8MB NAND FLASH

# BR0 base address at 0xff800000, port size 16 bit, GPCM, valid

mem [IMMR 0x5000] = 0xff801001

# OR0 8MB flash size, 15 w.s., timing relaxed

#writemem.l 0xe0005004 0xff806ff7

mem [IMMR 0x5004] = 0xff806ff7

# CS1 - NOR Flash 32 KB

# BR1 base address at 0xF0000000, port size 8 bit, FCM, valid

mem [IMMR 0x5008] = 0xf0000c21

# OR1 32KB size

#writemem.l 0xe000500c 0xFFFF8796

mem [IMMR 0x500c] = 0xFFFF8796

I download and debug it ,find OR0 register value is

I think OR0 is 0xffff07ae, reference the MPC8309RM.pdf

I dont know how to solve it ,who can give me some advise .

Thanks

Hello wei yang,

I could not quite understand what you are doing?

You're downloading u-boot binary from CodeWarrior to MPC8309SOM?

You changed the .tcl file from the "black" one to the “red” one? Trying to set OR0 to be 0xff806ff7 but you see it actually got 0xffff8796? And you think it should be 0xffff07ae although you set it to be 0xff806ff7? Looks puzzled.

Are you trying to debug u-boot?

Have a great day,
Lunmin

Thanks Lunmin

I am downloading u-boot binary from CodeWarrior to MPC8309SOM, the CW project for MPC8309SOM is boot from norflash, but i want boot it from nandflash，so i modify .tcl file from the "black" one to the “red” one, when i download it which show read flash ID error , current, only have the problem.

could you give me some advise.

have a nice day,

yang wei

Hello wei yang,

Why you need to download the binary into board?

If you're trying to flash the u-boot image into NAND, use the flash programmer and import the task 8309SOM_NAND.xml.
