Problem solved. The first line of init needs to be removed. That is to enable watchdog.

Well, it looks like not everything is working perfectly. I am unable to write anything to this range of addresses 0x0000-0x3FFF.

I took the original file and did a bitwise NOT on the whole file. Then flashed it and then read the file back and got a match on the above address range.

Is there something that could be different with this flash chip that is causing this?
