The previous u-boot version I use is U-boot 1.2.0, an ancient version. So I upgrade the u-boot to 2009-08. The platform is MPC8247. About build warnings, some warnings in printf for not proper type, and yes, I get the 64-bit printf warning :
nand_util.c:45:2: warning: #warning Please define CONFIG_SYS_64BIT_VSPRINTF for correct output! After I change the loff_t from long long to unsigned long, it works fine now. 2009/12/1 Scott Wood <scottw...@freescale.com> > > On Fri, Nov 27, 2009 at 08:14:41PM +0800, Peter Pan wrote: > > My u-boot version is u-boot-2009-08. > > In my U-boot, after I entered "nboot 800000 0 0", > > the following messages shows: > > > > Loading from NAND 1GiB 3,3V 8-bit, offset 0x0 > > Image Name: Linux-2.6.22.sac.rd > > Image Type: PowerPC Linux Kernel Image (gzip compressed) > > Data Size: 1045865 Bytes = 1021.4 kB > > Load Address: 00000000 > > Entry Point: 00000000 > > NAND read from offset ffffffff failed 0 > > ** Read error > > > > The image in nand is written in linux 2.6.22 using > > nandwrite -p /dev/mtd3 uImage > > This command works fine before. > > What u-boot verison is "before"?
