what is to be put in the bootargs?
The correct root device, of course.
the error message is : Root-NFS : no NFS server available.
And what was the other boot messages?
-setenv bootargs "root=/dev/mtdblock0 mem=128M ether=27,0,0xfc800000,0xfc800010,eth0 mtdparts=versatile:0x5c0000@0x1c0000(cramfs) video=vc:1-2clcdfb:"
Did the boot messages indcate that the kernel really created a MTD0 device as per your request? Did you enable command line partitioning in your kernel configuration? Did you enable cramfs support in your kernel configuration?
-setenv bootargs "setenv bootargs root=/dev/mtdblock0 mtdparts=armflash.0:0x65d000@0x2200000(cramfs) ip=none mem=128 console=ttyAMA0 video=vc:1-2clcdfb:"
This is obviously wrong but the kernel will ignore the bogus additional arguments "setenv" and "bootargs".
my cramfs is in flash at address 0x341c0000 while the basis of my flash memory is 0x34000000.
And does your kernel acknowledge this?
[BTW: this has nothing to do with U-Boot and it off topic at least on this list.]
