Hi All,
This is yogesh working on Davinci board, Where we have 32MB of Flash
which i am able to do read/write.
Flash mapping is as follows
0x02000000 0x02040000 (u-boot)
0x02060000 0x021A0000 (linux kernel)
0x02240000 0x02FFFFFF(flash file system)
where we are able to load kernel image and root file system image (jffs2
image) on to the flash after the kernel decompresses it gives out the
following error
