Other Parts Discussed in Thread: DM3730

hi,

I'm using dm6446, and want to change the uboot, then flash the binary to nand, but I want to flash the ubl and uboot from tftp_server on Linux environment.

The kernel print then nand flash partition is :

Creating 4 MTD partitions on "nand_davinci.0":
0x00000000-0x00040000 : "bootloader"
0x00040000-0x00060000 : "params"
0x00060000-0x00460000 : "kernel"
0x00460000-0x04000000 : "filesystem"

UBL and UBOOT info:

TI UBL Version: 1.12, Flash type: NAND
Booting PSP Boot Loader
PSPBootMode = NAND
Starting NAND Copy...
Initializing NAND flash...
Valid MagicNum found.
NAND Boot success.
DONE

U-Boot 1.2.0 (Jun 13 2008 - 18:13:34)

DRAM: 256 MB
NAND: 64 MB
In: serial
Out: serial
Err: serial
ARM Clock : 297MHz
DDR Clock : 135MHz
ETH PHY : BroadCom PHY Chip
Hit any key to stop autoboot: 0

I follow the instruction to flash the uboot.bin, but it print the BOOTME BOOTME..., uboot file has broken.

anyone can help?

Hi,

Which link did you follow to flash the uboot ?

Did you configure the boot pins properly and the jumper setting while flashing the uboot ?

You will see the BOOTME messages only in UART mode (Boot mode).

Can you list the actual steps you used ?

Prabhakar,

I follow the dm3730 guide

http://processors.wiki.ti.com/index.php/AM35x-OMAP35x-PSP_04.02.00.07_UserGuide

It can be flash the UBL and UBOOT binary from CCS successfully(UART mode) following this link

http://processors.wiki.ti.com/index.php/UG:_DaVinci_PSP_Installation_on_DM644x_EVM

I flash the uboot.bin from tftp_server in NAND mode:

1. connect RS232 to PC com1

2. power on the board(NAND mode)

3. in UBOOT console:

tftp 0x80800000 u-boot.bin(in tftp server directory)

nand erase 0x18000 0x28000

nand write 0x80800000 0x18000 0x28000

4. reboot the board(NAND mode), BOOTME can see in minicom console

I can't sure the uboot.bin start address is 0x18000 in 0x0-0x40000 print in first part.

If I use the UART mode when using serial port connect to PC, it can show the print message in console.

Does The progress have any problem?

Regards,

Bendney

Hi,

why dont you try out flashing with the serial flasher

http://processors.wiki.ti.com/index.php/UG:_DaVinci_PSP_Installation_on_DM644x_EVM#Flashing_DM644x_EVM_NAND_using_serial_flasher_utilities

And I dont see in the above steps that you set boot pins ?

I am not sure if this is rite nand write 0x80800000 0x18000 0x28000 I'll have closer this weekend.
