I know this isn't the best fit for my question but, hopefully somebody can redirect to the correct source. My issue is I have bad data crc's on a jffs2 nor flash file system and I need to determine root cause. That is I need to prove the failure is either hardware or software. I don't have the programmer (on another continent) for the nor flash that is being used so, I think my only alternative is to find the memory location in flash that is corrupted and write in a select patterns to confirm that the hardware doesn't have a failure with the data lines,address lines, or memory cells. I have found source code for the jffs2 file system and the mtd utils but, I haven't found a useful tool that will allow me to traverse past the first corrupted node and return the starting and ending memory location for each corrupted node composing the file. Do such tools exist?
Thanks, Harry
