Hi All, I am using MIP405T board and trying to reduce the size of u-boot.bin by disabling the drivers that i didn't need. But the image size is not changing because it is padding all 1's at the end of the image. Can anyone tell me how to remove these padding bits.

Image size is 512 K Actual image size is 207 K (approx.) u-boot version is 1.3.2

Hexdump of u-boot.bin is as follows:

00337d0 0000 0200 0000 0100 f9ff a8d0 faff 78f8 00337e0 faff 90f8 faff acf8 0000 1000 0000 0100 00337f0 f9ff 68ce faff b4f8 faff d4f8 faff 04fa 0033800 0000 1000 0000 0100 f9ff 68ce faff 08fa 0033810 0000 0000 ffff ffff ffff ffff ffff ffff 0033820 ffff ffff ffff ffff ffff ffff ffff ffff

Hi kuldeep nigam,

I think you want to change CONFIG_SYS_MONITOR_LEN in your configs/board/*.h board config file. Based on the numbers above, you should be able to reduce it to 256K. * You want it to be a multiple of a flash sector in size. * Your environment is probably stored in the next flash sector. * The change doesn't actually change the size of u-boot, it just changes the amount of padding in the .bin file.

The README file could probably stand some tuning. http://git.denx.de/?p=u-boot.git;a=blob;f=README;h=43fb1c0d8959b515c62e612280a0ba538d2921ce;hb=HEAD#l2144
