STM32F417ZG burn data to external NOR flash issue

Hi, guys

Recently, i'm working on a board based on STM32F417ZG chip. And i connect the FSMC bank1 NE1 to M29W128GH NOR flash chip, the address is 0x6000 0000. My tool chain is ARM MDK + J-link, and i make the flash algorithm according to 'Flash\S29GLxxx' in Keil MDK, and make the NOR flash init file according to 'FLASH_NOR.ini' in 'STM32F10x_StdPeriph_Examples\FSMC\NOR_CodeExecute\binary'. Now, my problem is, i can erase the NOR flash chip, but it always failed at address 0x6008 0000 in programming, that say, i can only write 512k data to the NOR flash!!! This is so weird, because i also write one NOR test program which runs in the internal flash, just like 'STM32F10x_StdPeriph_Examples\FSMC\NOR' do, everything is OK. I can't find anything wrong, so does anyone can give me some suggestions???

Thanks.

I attach my NOR init file and flash algorithm here.
