This usually happens for several reasons
1 Problems with the connected programmer to chip
2 Chip with bad sectors
3 Chip partially damaged
in case 2 check to write the data on the chip there are ways to do it

[size=18.72px][font=DengXian-Light][color=#e8e6e3]If a bad block is found during reading or writing IC, the programmer will skip the bad block. And directly proceed to the next block. [/color][/font][/size]

[size=3]Force data reads or writes regardless of whether the block is marked with a bad block or not. If the verifying displays error during [/size]

[b][size=4]#3 Replace Bad Block[/size][/b]
[size=3]Bad blocks are found to be written to the beginning of a specific block set, that allows the system to logically feel that the memory [/size]
[size=3]is still a contiguous area, and is generally used in partitioning mode.[/size]
[size=3]See detailed instructions in the example configuration as below. The number type in the start block (example: 900) is the actual [/size]
[size=3]replacement block index that is written to FLASH when the bad block is found[/size]
