Accessing onboard FLASH memory of CB34EX

[jacojordaan]

Does someone have an example of how to open/read/write a file on the built-in Flash memory of the CB34EX Netburner device (32-bit ColdFire MCF5234 processor)?
From the user manuals and examples I am unable to find the appropriate commands, C++ libraries and header files needed for this task.

Thanks

Hello,

In the latest release, there is information in the \nburn\docs\EFFS directory. Look in the EFFS Programmers Guide and the EFFS STD file system reference manual. Use extreme caution. You need to know exactly what flash chip you are using and its sector sizes. I would recommend opening a support ticket at support.netburner.com if you have any questions. Improper settings will overwrite the boot monitor, and you will need to return your device to the factory for reprogramming.

I downloaded the latest version of "EFFS-ProgrammersGuide.pdf" from the Netburner website. In chapter 6 ("Using the EFFS-STD File System with On-chip Flash") there is an example (which is also included in the Netburner development software) of how to use the on-chip flash. However, a library file "C:\nburn\lib\StdFFile.a" is missing from the Netburner development software. Because of this many function calls are not defined.

You will need release 2.2rc2 to get that file
