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
Bad Block Manage Mode
# 1 Skip Bad Block
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.
as below:
#2 Hard Copy
Force data reads or writes regardless of whether the block is marked with a bad block or not. If the verifying displays error during
writing, programming will be stopped. This method is generally used for technical maintenance when replacing memory chips.
#3 Replace Bad Block
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
is still a contiguous area, and is generally used in partitioning mode.
See detailed instructions in the example configuration as below. The number type in the start block (example: 900) is the actual
replacement block index that is written to FLASH when the bad block is found
Hope this helps you solve your problem.
