own external loader-custom board with 1gb nor flash which is not available in bsp

[jr_engr_mbed]

Hi ST members,

Where can I find the BSP components for the NOR flash with Part No: MT28EW01GABA?which is not in h7's bsp.

If I want to create my own external loader, I need to add the MT28EW01GABA.c and MT28EW01GABA.h files to the project. However, I can't find these files anywhere. Can anyone advise on what to do?

Thank you.

Best regards,

Perhaps put your embedded software engineering hat on and write them? Making stuff that doesn't exist yet is in my job description.

For things not readily available to copy, you could understand the data sheet for the part, and perhaps find something close, and port from there.

Perhaps don't look for the fully qualified part number, as the extended family of MT25EW parts, and those in slightly different packages will all operate in materially the same fashion.

Does the Micron part behave materially differently from U5 to H7. Might have to deal with QSPI, OSPI and XSPI changing naming convention, but that's a 99% search-n-replace exercise.

Why use parallel? Most people have migrated to serial memories for smaller foot-print, less complicated packaging  (ie SOIC,TSOP) and less MCU pins eaten up. And package consistency between vendors.

So I don't have to find later..

I remember another from earlier, but that might be this thread, recall you talking about EWARM in that one too.
