I think you have to modify nbl programmer in ccs3.3 envirment ! it just read
two blogs from nand flash.
#define APP_DESC_START_BLOCK_NUM 8
#define APP_DESC_END_BLOCK_NUM 9
if your nand page size is 64k,it equal 128k!
and you no need to modify nandprogrammer ,because it can accept blogs from 8 to
14(checked it in source)!

主题： RE: the u-boot size
I have read this structure before in the nandprogrammer code. Must i use the
nandprogrammer in ccs to change the descriptor?

SubjectRE: the u-boot size
U-Boot descriptor is located at block # 8.
Its format is:
/* Some of the parameters are modified runtime */
unsigned int appdesc [] = {
0xB1ACED22, //Magic number
0x0000000A, // Start block in NAND
0x81080000, // Start address in DDR
0x81080000, // Entry point
0x00000200, // No. of pages for the complete Application
0x00000000 //compression flag
};
You need to update descriptor as per your requirement.

You have to increase “no of pages” in u-boot descriptor.

Subject: the u-boot size
Dear all:
Recently,i modified the u-boot of DM355. Now the size of u-boot is 129KB. When
i updated the u-boot using the u-boot self, the system reported error. But if i
used the old version which i modified yesterday, the size is 127KB, everything
is OK.
the command line:
tftp 0x80700000 u-boot-0217.bin(129KB)
nand erase 0x140000 0x30000
nand write 0x80700000 0x140000 0x30000
when i rebooted the system, the display is below:
U-Boot 1.2.0 (Feb 17 2009 - 09:54:18)

Hit any key to stop autoboot: 0
Is there limit of u-boot size? Or any other suggest?
