<br><font size=2 face="sans-serif"> The flash I am using on

Any help or pointers to solve this will be of great help.</font>

<br><font size=2 face="sans-serif">Strange thing is everything works fine

read/write/execute files from it.</font>

Hi,<br>
I'm not using that board so I can not tell which is the correct value,
but looking at the output you send it looks like the erase size you passed
when creating the image file is wrong. I suggest you to find the appropiate
value and create the image. For an mpc5200b it happened to be 0x20000.
May this would help.<br>
<br>
Good luck.<br>
<br>
Pedro.<br>
