AM3352: BIN2NAND

Hi,

Version bin2nand-1.0.5.0 is the latest that we have and it only supports BCH8.

HI  Jianzhong

thanks for your reply ,and Customers can only make a software product  which supports BCH16 by oneself?

if AM3352 have BCH16 ,why  not make a software produce which supports BCH16? I think just need port code for am3352.

it should easy。

looking foward to your reply。

Yes, that's correct. Users will need to add BCH16 by themselves. Some customers have done that already, for example, this thread has a StarterWare patch to implement BCH16.

We currently don't have any plan to add BCH16 to bin2nand tool.

this just add bch16 at startWare，and this work  i had do it 。i do not know what is the relationship between the two.

i need add ecc data at .bin file which  generated by the CCS,  add bch16 at stareWare? how does it  achivev my goal?

i think i should explain my need again by a  example

for example ;my project name is nand_boot,and  it can generate a .bin file by ccs generated,this file name is nand_boot.bin which generated by the CCS.and the nand_boot.bin is not contain ECC data。so we  use BIN2NAND (is a applied software ) to add ECCdata at nand_boot.bin,it will create a new file ,like nand_boot_oob.bin。 and then i can use tool load this file in nand_flash before it  soldering to the circuit board.

  so i can not understand what is the relationship between the add bch16 at stareware and my need?i think there is no relationship between them，because  add bch16 at stareware,the ecc data also calcute by am3352,users only can get ecc data ,but do not know how to calculate。so it get ECC data must by am3352.but i want get ECC data just by PC。

   so the question is user not have algorithm which AM3352 calculate ECC by BCH16,how to add ECC data at .bin file by pc?

Hi,

Sorry about not making my point clear earlier. What I meant was that we had customers who implemented BCH16 by themselves. The example I gave was for bootloader, not for bin2nand tool. My point was it shouldn't be too difficult to implement BCH16 in bin2nand tool.

Thanks and regards,

Jianzhong

thansk for your reply

       implement BCH16 in bin2nand tool just need bch16 algorithm,i not find it ,  bch16 algorithm which AM3352 used  is  open source ?

     if not open source ?how to  implement BCH16 in bin2nand tool. if open source , it is easy to implement BCH16 in bin2nand tool.

Hi, 

Sorry for my delayed response. So you wanted to know how BCH16 is implemented by the AM335x hardware, right?

Thanks,

Jianzhong

Not quite right

    bin2nand supportts BCH8, the tool uses algorithms with BCH8,  now  if it want support BCH16,we need algorithms with bch16,Actually I don't care   how BCH16 is implemented by the AM335x hardware, i just need TI can Provide an interface.I just need input data ,it can output BCH16 Data。then i can add ECC data at .bin file by pc

Understand you point. But we don't have BCH16 support in bin2nand tool and don't plan to provide it in near future, you'll need to implement it by yourself. To do that, you would need to know how it is implemented on AM335x SOC. Is that right?

yes  ,it is

Ok. Let me check internally how to get that to you.

OK,Thanks。

hello ,Is there any progress?

Hello Mengdong,

Sorry for taking longer than I had expected. Our internal team updated the bin2nand tool to support BCH16. I've sent you a friend invitation. I'll email the updated tool to you once we're connected.

Thanks for your patience.

Jianzhong

thanks for your support,  and i have  accepted your  fiend invitation.  thanks again.
