Hi,
I want to calculate ECC for Flash F021 using my own script:
According to SPNU503 : "Each ECC[x] bit represents the XOR of all the data bits marked with x in the same row & For Odd parity, XOR a 1 to the row’s XOR result. For even Parity, use the row’s XOR result directly."
and using the given examples in SPNA126 I did not get the same results :
DATA: 0x954f6d2f2992a9b6 MY_ECC : 0x52 SPNA126_ECC: 0xAA
DATA: 0x2f92b288d3e1a7bd MY_ECC : 0x25 SPNA126_ECC: 0xDD
DATA: 0x5d80c176a04cfed0 MY_ECC : 0xf9 SPNA126_ECC: 0x01
DATA : 0x0000000000000000 MY_ECC : 0x0c
can you provide the algorithm of the ECC function ?
thank you in adavance !
