LS1046A QSPI NOR Flash Programming C Code

DaT63 — Thu, 16 May 2024 10:10:57 GMT

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.

Hello,

accessing the flash memory trough the programmer or u-boot is of no use for me. I need to do it within a custom application. There must be the possibility to do that, I think that NXP should provide a minimal support to do such operation

Hello,

Please open a new technical case (not community thread) and ask for your c code requirement, if there is something helpful for you it will be provided there.
