AM3352: BIN2NAND which supports BCH16

Part Number: AM3352

now i have tool,bin2nand which support BCH16

i use it ,found some question .

Bin2nand_v1_2_0 -spare 128 -bch 16 -block 64 NAND_boot_ti.bin convert1.bin

I call bin2nand from the above command line,it have some question?    

for example.  address=00000000   ,data is 50 b4 00 00 00 04 2b 04 6c 00 9f e5 db f0 21 e3

after use bin2nand, the new file   address=00000000 data is 50 d0 94 00 00 00 04 2f 40 6c 00 c2 9f d1 85

address=00000000  the data is should be no change,and other address data is aslo wrong.

so if add ECC data ,ADDRESS=00000000-0X00000800 the data is should not change .

and Address 0x00000800  -0x00000870 is add ecc data

    I'm not sure why this is happening.  I don't see this on any test files i ran.  Can you post your NAND_boot_ti.bin?

     i have  emailing a co-worker of yours,i send nand_boot.bin to hime  ,and  he give me  convert1.bin file with add BCH16 ECC data .

     like picture ,

    • The data in the red box should be the same.

    I'm confused because the convert1.bin i sent you does not match yours

    Can you run the executable again?  This is what mine looks like:

    C:\bin2nand\test>bin2nand_v1_2_0 -spare 128 -bch 16 -block 64 NAND_boot_ti.bin convert1.bin

    The file I opened was the one your colleague sent me,It's strange to see different data when we open it.

      i train it again use binnand_v1_2_0 ,the problem still exist。Can you ask your colleague to verify it?Check the details, and I'll verify when he succeeds.

    Hi Mengdong,

    First of all, I opened file convert1.bin that I sent to you and saw this:

    This is different from what you saw in your Notepad++ editor. Can you double check if you were looking at the one that I sent to you or the one you generated?

    Secondly, I ran the tool to generate the BCH16 data as below:

    D:\Sitara\apps\bin2nand\bin2nand_1.2>bin2nand_v1_2_0 -spare 128 -bch 16 -block 64 NAND_boot_ti.bin NAND_boot_ti_bch16.bin

    The output I got is identical to file convert1.bin which was generated by James and sent to you. Please make sure you run the tool with correct options.
