Hi, All,
I'm porting uClinux to our board based on ARM946E-S. Now, I generated an
uncompressed uClinux kernel image and romfs (txt+data+romfs) with
command like:
cat image.txt image.data romfs > image.bin
And objdumping results like:
===================================================================================
>arm-elf-objdump -h linux-2.6.x/linux
linux-2.6.x/linux: file format elf32-littlearm

Instead of a standard Linux bootloader. Our board has a simple
bootloader, which can
1. Copy image to some place in main memory;
2. Transfer the control to kernel.
My questions are:
Where should I put the uClinux kernel at 0x00008000 in the main memory?
Do I need to make some changes on our bootloader for booting uClinux?
Thanks a lot.
WSL
