How can I handle the second qspi flash?

Hi,all

 

hardware:zc706

software:petalinux2016.02

 

Use the below three instructions, I can handle the first qspi flash:

1:sf probe 0 0 0

2:sf erase 0 0x1000000

3:sf write 0x08000000 0 0xffffff

 

when I want to handle the second qspi flash with below instructions:

1:sf probe 0 0 0

2:sf erase 0x1000000 0x1000000

3:sf write 0x08000000 0x1000000 0xffffff

 

I used md.b command to check the write memory region, the data didn't write into the flash. I suspect I can't handle the second flash correctly. 

1.How can I handle the second qspi flash?

2.what's the usage of command "sf probe 0 0 0", what's the meaning of parameters "0 0 0"

 

Thanks in advance

 

 

Tom
