Well it seems it is the problem ... i have generated cramfs on my x86 and my target is ppc . is there a simple trick to make my cramfs image correct for ppc ? should i build my cramfs image on the target ? thanks, Julien. details ------- ok i boot my target over nfs, and i try to mount my cramfs with : # mount -t cramfs /dev/mtdblock/2 /mnt/temp wrong magic ...... # dd if=/dev/mtdblock/2 of=/root/toto.dat bs=1024 count=1 then i switch to my PC (x86) to look at what i have : #hexdump /root/toto.dat | more 0000000 3d45 28cd 0000 0001 0000 0000 0000 0000 0000010 6f43 706d 6572 7373 6465 5220 4d4f 5346 0000020 6344 2423 98f1 b87f daf3 58a0 b74a a046 0000030 6f43 706d 6572 7373 6465 0000 0000 0000 in cramfs.h : #define CRAMFS_MAGIC 0x28cd3d45 /* some random number */ -- Julien Eyries R&D engineer Thales Broadcast & Multimedia (ex-thomcast) email: julien.eyries at thales-bm.com fax: 33(0) 1 34 90 31 10 tel: 33(0) 1 34 90 31 01 ** Sent via the linuxppc-embedded mail list.
