Dear ST Developers, I think, that my problem is your bug

[EEuge]

Hello!

Problem is described here https://community.st.com/s/question/0D53W00000YU9O3SAL/loading-object-code-error

I try to find reason of problem by creating new clear project.

I created project in cubeMX 6.1.1, configured SDRAM, LTDC, QSPI, DMA2D

Than I added to H743.SCT this section

LR_EROM1 0x90000000 0x2000000  {    ; load region size_region
 ER_EROM1 0x90000000 0x2000000  {  ; load address = execution address
*.o (ExtFlashSection)
 ;*.o (TextFlashSection)
*.o (FontFlashSection)
  }
}

Keil project downloading and startin without any problems

This project is here https://cloud.mail.ru/public/uUgS/jxTK5fmg1

NEXT STAGE

 

Than I edit project in TouchGFX editor, add one button, generate code, and build it in KEIL.

Than I download it to flash.

Then starting debug I get error, on this stage

 

this error

 

this error is not occured when I delete from H743.sct this code

LR_EROM1 0x90000000 0x2000000  {    ; load region size_region
 ER_EROM1 0x90000000 0x2000000  {  ; load address = execution address
*.o (ExtFlashSection)
 ;*.o (TextFlashSection)
*.o (FontFlashSection)
  }
}

But I need this code for keep pictures in QSPI.

HERE IS MODIFIED PROJECT

Please, anybody, who have H743 board, please, try to download both projects an answer me - what reason of problem?

This question is into KEIL support and not ST bug. But i mean KEIL is good, but for example debug with more configs is impossible, attach to running MCU is one miracle and price for unlock is ...

You need to select a Flash Algorithm for the external QSPI Flash

[EEuge]

No!

IT is TouchGFX problem.

If I set TouchGX off in CUbeMX - problem disappeared.

Sorry , when you turn it off, sections ExtFlashSection... is empty = problem disappeared.

"when you turn it off, sections ExtFlashSection... is empty = problem disappeared."

Really? YOu really think, that I so stupid?

After setting touchgfx off, I set ExtFlashSection to *.SCT MANUALLY!!!!!

I add

LOCATION_PRAGMA("ExtFlashSection")
KEEP extern const unsigned char _blue_buttons_round_edge_small[] LOCATION_ATTRIBUTE("ExtFlashSection") = // 170x60 ARGB8888 pixels.
{
    0x00, ...................
}

But problem (if touchgfx is off) not appears!

[EEuge]

If you so clever - can you create simple project, add to it touchgfx with one button, and try to start on KEIL?

[MM..1]

Sorry your example lines result

..\main.c(39): error:  #77-D: this declaration has no storage class or type specifier
  KEEP extern const unsigned char _blue_buttons_round_edge_small[] = {    0x00, 0X05 };
..\main.c(39): error:  #65: expected a ";"
  KEEP extern const unsigned char _blue_buttons_round_edge_small[] = {    0x00, 0X05 };

when i remove KEEP result warning extern have init, and when i remove extern compile ok,

but optimizer remove it from link when is not used...

i use this syntax

const unsigned char _blue_buttons_round_edge_small[] __attribute__((section ("ExtFlashSection"))) = {    0x00, 0X05 };
 

result to this

compiling main.c...
linking...
.\OUT\test.sct(21): warning: L6329W: Pattern *.o(ExtFlashSection) only matches removed unused sections.

Hi,

I havent downloaded you project (not really allowed to, shady link), could you give more info on how you configured TouchGFX in your project ? If you look at the application template available in TouchGFX Designer for the H747-eval, you can see in the folder /projectName/TouchGFX/target files that we have set ourselves. Those are not generated by TouchGFX Generator. There are more steps involved than just setting it in CubeMX.

.....

How it is difficultly...

Look:

I've attached CUbeMX project.

I ask somebodyx who have CubeMX+Keil+TouchGFX Designer to do next:

1. Generate project for Keil from CubeMX project
2. Open TouchGFX project in TOuchGFX Designer and add one button
3. Build project in Keil
4. Run project with debugger

Please....
