Linux/66AK2L06: Ease the original linux kernel , cannot boot by uboot

thxin
Prodigy 50 points
Part Number: 66AK2L06


Tool/software: Linux

I follow this link processors.wiki.ti.com/.../Program_EVM_UG

and format the nand by the command

$DSS_SCRIPT_DIR/dss.sh program_evm.js evmk2l-le format-nand

and when I do the following command
$DSS_SCRIPT_DIR/dss.sh program_evm.js evmk2l-le nand

it stuck and cannot flash the nand successfully.

I use the following command to load the uboot to the nor, 
$DSS_SCRIPT_DIR/dss.sh program_evm.js evmk2l-le nand


and when I switch to spi bootmode, i can type uboot command. I try to use tftpboot, but the dhcp doesnot work.

Someone has the similar experience on the 66AK2L06 EVM, please let me know how you boot the linux kernel with uboot.

Thanks!

    There is damaged block in the nand flash. 
    

    
Here is the output after I run the following commands
    
$DSS_SCRIPT_DIR/dss.sh program_evm.js evmk2l-le nand
    
It takes about tens of minutes to load the nand.bin file, and takes another half hour to flash the blocks. Because there is a damage block (block 6), the procedure try to flash the nand server times.

    Hi, Thxin,
    

    
In your first post, you mentioned :
    
   [I use the following command to load the uboot to the nor, 
    
    $DSS_SCRIPT_DIR/dss.sh program_evm.js evmk2l-le nand]
    
You really meant the command being $DSS_SCRIPT_DIR/dss.sh program_evm.js evmk2l-le "nor", right?
    

    
Let's clarify a few things first. Programming NAND is to program an image of Kernel and filesystem to the NAND, but programming NOR is to program the uboot image to NOR. The U-boot is always booted from SPI NOR, but booting kernel can be one of the following: net (tftp/nfs), ubi (nand), and ramfs(tftp/ramfs). It is controlled by "setenv boot net/ubi/ramfs ". 
    

    
To burn the NAND, there are equivalent uboot commands to do it, You may want to "pri env" and understand how it is done. The commands are "run get_ubi_net" and "run burn_ubi". Please note that there is a size limit of NAND. We noticed that the tisdk ubi file is way too large to fit in the NAND. The arago ubi should fit. Therefore, name_ubi in the u-boot environment variable should reflect which file to get.
    

    
Using the u-boot commands to program the NAND, or boot kernel using net or ramfs, you will need to have dhcp and tftp setup. In ProcSDK bin directory, there are scripts provided to help you set up. You may also refer to information on  internet for linux tftp server and dhcp server set up.  Using net boot, you will also need to set up NFS server.
