Subject: Questions on FRU.
Hi,
I had a few queries regarding the FRU programming
utility from Intel for IQ80310:
1. What is the maximum size of the image that
one can program using FRU on IQ80310?
ANS: The size of the flash device ( 8 Megabytes?)
2. Let's assume that we have two images,
foo1.img and foo2.img that need to be put
on the Flash. foo1.img needs to be flashed
at 0x00000000 and foo2.img needs to be
flashed at 0x00080000. Can this be done?
One intuitive way is to give the start
address as 0xa0800000 and sizeof(foo1.img)
and fuse the first image.
Then, change the start address to 0xa0880000
and give sizeof(foo2.img) and fuse the second
image. Will this work?

With the current FRU that you may have, it will not work. This will be
possible with the new release.
The current FRU erases the entire flash for each download. TRo accomplish
the task you just mention,
short of having a rew release you would have to download both files in 1
step.
This ould require creating a single file from your 2 images such that
foo1.img start at 0x0 and foo2.img start at 0x80000. To do this, pad the new
file between ( 0x0 + sizeof(foo1.img) and 0x7ffff) with 0xff and then
download the new file starting at 0xa0800000. multiple download capability
will be possible in the next release.
