Hi,

Can anyone tell me where I can download the latest version of spifi_drv_M4.lib please? The version that comes with LPCOpen 1.03 doesn't support the latest large serial flash devices, e.g. the Spansion S25FL512SAG devices (512Mbit).

We need this urgently for a project where we've designed a board with this device on, assuming that it would be supported like other members of the family, so it's seriously bad news if we can't get it supported!

What is the largest size currently supported? It seems impossible to find documentation for this library, including the error codes etc.

Thanks
Richard

No-one from NXP can help me? We really need this update otherwise it's a board re-design!

Hi rgledhill,

Have you considered using the SPIFI registers to perform the needed operations? The driver is only one way to work, and it seems that it is not supported very well. I've written a blog showing some simple register access examples and I've posted an XIP storage example as well.

Hi rgledhill,
Are you using LPC43xx flash part or flashless part? If you are using flash part you can boot out of internal flash and use examples mentioned by Noah thereafter to interact with QSPI flash.

Hi Noah: thanks, that's a very helpful start but I'm actually after using the SPIFI library to implement the erase/program access to serial flashes so that I can run the Keil file system over it. It does work fine except for not supporting chips newer than a year old...

Hi mc: I'm using the LPC4357...

Thanks both!
Richard
