Reserving an area in image with mkifs
Hi,
I'm working on a project where there are two 'images'.
The first is the IPL. It is linked directly to FLASH to the area of memory it will run. The processor we're using has
it's reset vector practically in the middle of flash. So, the IPL has a small bit of code at the reset vector which
does a few things but then jumps to the rest of the IPL which is located at the start of FLASH.
The IPL and the image file system are loaded onto flash separately. The reason they are kept separate is because we are
doing in-field updates and do not want to have the IPL touched by these updates.
The problem is creating the image file system. So far, it hasn't been a problem as the length of the ifs has kept it
from overwritting the the reset vector. Now however it is starting to touch and overwrite the reset vector memory
location.
My question is: How do I create an image file system that has a portion of it reserved so that when loading it, I can
specify a range (offset 0x700100 plus some length) that will be skipped.
Thanks
Kevin
