when the microtronix add the upload function into the nios2 ide , it's very easy to write the file into the flash . but i have some question

1) what's the destination address in the flash when load the kernel image vmlinuz.bin

2) what's the destination address in the flash when load the filesystem image

3) does the kernel image in the filesystem like the normal linux ?

4) when the kernel startup , how the kernel konw where the romfs system on the flash , is the kernel startup command line " root=/dev/mtdblock0 ro" enough to let it the the location?
