how to load and read fontflashsection and textflashsection in qspi?

[Zakba.1]

I could successfully load and read images (ExtFlashFection)in QSPI but when it comes to font and text it doesn't work... I use stm32f767+qspi+sdram+keil environment... and you see the .sct file and my project here.

can anybody help me?? internal flash runs out of space because of fonts and text and I don't know what to do... thank you in advance.

Hi,

Just took a look at your map file and it seems there's lots of stuff in external flash

Thank you sir for replying. but it still doesn't work. Before adding font and text to qspi everything is ok. but when I add them to the scatter file LCD shows just garbage...Is there any other thing I can do?

[Martin KJELDSEN]

This is the .sct file re: qspi for the f769-disco tbs

LR_EROM1 0x90000000 0x4000000 { ; load region size_region
 ER_EROM1 0x90000000 0x4000000 { ; load address = execution address
 *.o (ExtFlashSection)
 *.o (TextFlashSection)
 *.o (FontFlashSection)
 }
}

Thank you so much...

I dont use KEIL with TGFX, but primary try dont place TextFlashSection in QSPI.

Next debug your code, need switch mapped mode before tgfx init.

Thank you sir. I deleted textflash section from scatter file and it worked...

[Zakba.1]

yes sir. I want to place TextFlahSection in ext flash too. As you can see in the photo QSpi is initialized before Touchfgx in the config tree...
