I port the uboot for my board. But when i boot from parallel nor flash of my board, i can not get the flash infomation. The parallel nor flash is sst39vf3201. I can read from the nor flash, but i can not erase and write the nor flash.
The chip in my board is bf609.
The uboot version is u-boot-2011.09-2012R1-RC4.
I have attached the board header and the sst39vf3201 datasheet.
