[U-Boot-Users] Uboot image size reduction
Hi all,
I am trying to build a uboot image of size 90k.
My full image having all the functionality has a size of 169k. Till now i am able to reduce its size to 106k.
Things i did to reduce it to 106k are
-- disabled all the commands except (loadb,saveenv,setenv,help,printenv,protect) which are not used to load the kernel image. -- disabled the longhelp macro.
Is there any possibility to compress some parts of uboot and decompress into the memory when needed?
Also i am open to any suggestions which can help me to redue the image size close to 90k
Thanks in advance. Vijayakumar

90 k is a funny size. It does not match typical flash sector sizes. How did you come to such a size restriction?

No. if you think about the code needed to do that you will soon see that this does not fit into U-Boot's design principles (easily portable, provide success [and error!] messages as early as possible, etc.).

Use latest compilers, i. e. GCC 4.x; they optimize much better than older versions.
