LS1046A QSPI NOR Flash Programming C Code

[DaT63]

Hi,

I need to access the boot NOR Flash memory by C code for read/write/erase operations. I wonder if there are C code examples, API, libraries, ... already available which are not OS dependent

Regards

Daniele

Hello,

You can use CW flash programmer to perform those operations, Please find the attached file and take a look on chapter 7.3 Using flash programmer.

Hello,

I do have a CW flash programmer, but if I am asking for sample code is because I need to do such operations inside an embedded software application (not Linux). I wonder if somewhere is available a sort of SDK or at least an Application Note 

Thank you

Hello,

We don't have a c code example, but, you can use sf command under U-boot to perform those operations.
