It appears that whatever you are trying to burn into NAND flash simply does not fit.

Try using LoLo's info command to view the amount of memory on the board. Then take a look at the size of the file you are trying to put in there.

Also, you ought to be using YAFFS (or some other file system) to burn something into NAND. In general, anytime you use NAND flash you want to go through an appropriate flash file system that can handle bad-block management, errors, etc.

Check the LogicLoader's User Manual for information on using YAFFS. In general, you:

*losh> add-yaffs

*losh> mount yaffs

*losh> cp whatever file you want into YAFFS (try TFTP for this)

* access the file however you like using the normal LoLo file commands

The NAND FLASH memory available is 64 Mbytes. Even the size of file is also very less near about 1K. I am using yaffs for burning the nand.
As u suggested to use tftp but I want to use serial port only. Please help me out.

You don't use the load/burn command combination to put something into YAFFS. load unpacks a file into a RAM buffer or its execution space. burn flashes the file put in the RAM buffer by the load command. Where it gets flashed depends on the options you give it or the format of the file (ELF, S-REC, MS-BIN, raw-binary). The LogicLoader User Manual has a section dedicated to explaining this behavior.

You need to use the cp command. However, the cp command doesn't take data over the serial port. Mainly because the command can't guarantee the portion of the file's format that describes size, location, etc. will come at the beginning of the data stream.

Therefore, if you want to cp something into NAND flash, you need to:
1) create the YAFFS partition
2) mount the YAFFS partition
3) copy the file from another mounted file system (CF Card, YAFFS NOR partition, etc.) or from a TFTP server
