Have TouchGFX 4.25 access fonts from external SERIAL flash

[J-F]

Hi all,

I managed to move my fonts to external serial flash.

Now I want TouchGFX 4.25 to retrieve and use them but it doesn't seem to work.

My question is this. Is it possible to do so, and if yes, is there some kind of appnote on this?

Thanks

Directly this work only for memory mapped mode. And your sentence 1.manage move fonts 2.use in TGFX is oposite force... Normal you mark fonts to external and linker do job. After build you load hex or oher format over external loader to right place...

Hello @J-F.

Aside from the documentation referenced above, you can refer to one of the following TBSs available in TouchGFX Designer, if you are looking for reference implementations:

• NUCLEO-C071RB + GFX01M2
• NUCLEO-C092RC + RVA15MD
• NUCLEO-G071RB + GFX01M1
• NUCLEO-G071RB + GFX01M2
• NUCLEO-H503RB + GFX01M2
• NUCLEO-U083RC + GFX01M2
• NUCLEO-U385RG + RVA15MD

All of these TBSs use fonts stored in external serial flash.

Best regards,
Johan
