[ECOS] Compilation problem with Redboot on assabet (no memory region specified for section .got and .got.plt)

[benoit dot cousson at philips dot com]

Hi,


I try to build Redboot for assabet with network support, but the RAM image does not work. Although I followed the process described
in documentation:
"ecosconfig new assabet redboot"
"ecosconfig import hal/arm/sa11x0/assabet/current/misc/redboot_RAM.ecm"
"ecosconfig tree"

and after copying image in /tftpboot :
"load /tftpboot/redboot.srec"
"go"
and nothing...


I have also try with the redboot_ROM.ecm, but I have strange result. The size of the redboot.bin file is about 1,6MB ???

 Here is the result of objdump:

 install/bin/redboot.img:     file format elf32-littlearm

 The only differences with the working redboot.rom are sections .got and .got.plt.
These sections also generate warning during the link: "no memory region specified for section .got".
What does it mean? The linker store these sections in 0x00000000 and 0x00000008, and pad with zero until 0x50000000. That the reason
why the .bin file is so big.

I do not have CVS access, so sources come from ftp snapshot (ftp://ftp.skynet.ie/cvs/), downloaded 2 days ago.

I use HardHat CDK 1.2 for cross compilation on a Mandrake 7.2 linux.
Is it a configuration problem ?


Thanks in advance.

 Benoit.
