Hi,
I cannot figure out some basic questions on ramdisk by reading ramdisk & initrd documents in linux tree and linux-ppc maillist.For the sake of more detailed explanation on ramdisk from DULG and this maillist,I post the topic here for some help.Sorry for bothering you all.
1.Is ramdisk a must or not for embedded application?In URL http://www.redhat.com/docs/manuals/linux/RHL-7.3-Manual/custom-guide/s1-cust...
and some web pages,they say an initrd image is needed for loading your SCSI module at boot time.So if I didn't use SCSI module,I would save the initrd image.Is that so?
2.What advantage does ramdisk have?In which situation should we use it?
3.After programming SELF 8xx image(from ftp.denx.de) to flash on lite_dw,u-boot+kernel+ramdisk worked fine on LCD panel(Thanks wolfgang providing such a workable ramdisk).It displayed "Application running".What does application refer to?Busybox or ramdisk itself?If I want to make my added application in ramdisk run automatically,how should I do?
Any advice is appreciated!
Best regards,
Sam
