Kim, You should use mtd2 partition of cause. There is an error in spraaa0 AppNote. And not ftl_format, it is not so good for the NAND, better use flash_eraseall. But better to do it by the u-boot: tftp 0x85000000 uImage nand erase 0x60000 0x400000 nand write 0x85000000 0x60000 <uImage size>
to load the kernel just use: nboot 0x80700000;bootm BR, Maxim Shabrov ------ Odin TeleSystem Inc., Russian Office. web: www.odints.com ICQ# 10139715 Skype: Maxim_Shabrov > -----Original Message----- > From: Kim Klaiman [mailto:[EMAIL PROTECTED] > Sent: Tuesday, September 11, 2007 10:38 PM > To: Maupin, Chase; [email protected] > Subject: RE: Booting DaVinci EVM from NAND Flash > > Thanks Chase, > > I have now U-Boot on my NAND, I can boot the kernel from nfs. > Now I'm trying to write the kernel to NAND flash following > spraaa0 and I have some troubles doing it. > When I try " ftl_format /dev/mtd0" I get "open failed: > Permission denied". > Actually, formatting /dev/mtd0 doesn't make sense to me, > since this partition is reserved for the bootloader, isn't it? > > > -----Original Message----- > From: Maupin, Chase [mailto:[EMAIL PROTECTED] > Sent: September 11, 2007 11:14 AM > To: Kim Klaiman; [email protected] > Subject: RE: Booting DaVinci EVM from NAND Flash > > Kim, > > The safest thing to do is to set the S3 switch to 1100111110 > which is UART mode.
