error : memory exhausted

When I try to run my application I get "memory exhausted" message. I have passed "mem = 32M" as kernel parameter to increase the ram allocation to kernel to 32 MB. But it still doesn't work.

I don't understand your problem about padding.

One important difference between RISC and x86 is that RISC can not access unaligned word.

eg, read 32 bits word from address 4 is OK, but read 32 bits word from address 5,6,7 is wrong.

so you may need to 4 read bytes from address 9, and shifted to make a 32 bit word.

This applies when you read or write a unaligned member in a structure.
