nand ecc

[punnaiah choudary kalluri]

Hi,

  I have the following confusions regarding the nand ecc algorithms:
Haming and BCH

Request your help to clarify the below concerns.

Hamming  Mode:
   What will happen if the data has more than two bit errors for codeword?
   Will the nand_correct_data() function returns uncorrectable ecc error ?

BCH mode:
 Assume that the BCH block can correct upto 24bit errors. what will
happen if the data
has more than 24 bit errors?
Will the nand_bch_correct_data() function returns uncorrectable ecc error?


Regards,
Punnaiah
