Hello,
I am going to run ARM with kernel 2.6, 32M DRAM and 16M Flash (Intel
J3). Could you please help me the following questions:
Redboot> load -v -r -b 0xA00000 ramdisk.gz
Redboot> load -v -r -b 0x80000 zImage
Redboot> exec -r 0xA00000 -c "console=ttyAM root=/dev/ram"
1. I guess the address is the DRAM entry address. If the ramdisk.gz = 4M
and the decompressed ramdisk = 12M, and zImage = 800K, I guess that the
ramdisk will be allocated in DRAM between 0xA00000 - 0x1600000 and the
zImage will be allocated in DRAM between 0x80000 - 0x148000. I guess
those address sections of ramdisk and zImage are occupied during
operation time, is it correct?
2. Can the DRAM loading addresses be selected anywhere, or it can only
be selected in particular segments?
3. Do we need to allocate the memory (stack and heaps), or the kernel
will use the rest of the available DRAM?
Thank you.
Jim
