Hi,

 

My board uses two FLASH,NOR FLASH and SPI FLASH。

SPI FLASH :AT45DB161D.

 

My initialization code in the Annex .

 

When I use the NOR FLASH startup added initcode file is no problem . ldr file from NOR FLASH start automatically.

I that this initcode file is no problem .

 

 

SPI MASTER starts , I use two programs to do the experiment :

 

1 , a simple led program , the program did not use to SDRAM .

Ldr file can be generated automatically start .

 

 

2,A TFT test procedures , a number of image data into the L3 .

 

Ldr file generated later programmed into the FLASH,Does not start automatically。If this program start from nor flash is normal.

In initcode file , I modified the DDR2_init, because my DDR2 is 256MB , ezkit 's is 128MB .

 

SPI FLASH reading and writing I have already been verified , is not a problem.

I do not know why SPI MASTER fail to start .

 

Thank you.
