When developing touchGFX applications you tend to get a pretty high memory need.
I'm working with the CubeIDE integration of TouchGFX and tried to add a third screen (with a third background image). I got an error saying that the application would not fit in my FLASH.
After a bit of digging it seems that the linker files don't mention the QSPI at all.
I can add that to the linker files but I would like to know if there is an official way of doing this?
I found some documentation on this but I'm not sure if this is the right way to go about it.
What goes where in the memory and how do I control it? if at all?
Thanks!
Solved! Go to Solution.

I will definately go through the videos and follow your suggestions. However, you mention one of the prerequisites are to have a working project in Cube IDE, which I don't. If you look at my error log, there are a number of "multiple definition" errors. Do you think these will be resolved by enabling QSPI?
Update: Editing the linker script solved the flash issue, but all the other osWrapper issues remain.

Just see my other video: https://www.youtube.com/watch?v=43qQhrXc3n4
this will show you how to set up a working project in CubeIDE. All the videos are made in succession so you can start at the first (the one i just linked) and continue to the others :)

Outstanding work on those videos! I was now able to build and run debugging on my project. I did however have to exclude an additional file to remove all the "multiple definitions" errors in the osWrappers.
There are two files under touchgfx/framework/os called "OSWrappers.cpp" and "OSWrappers_cmsis.cpp" that have functions defined with the same names/class. Excluding either one removed the errors, but I don't know if this could cause further problems down the line.
When the project buildt the first time and I was debugging, I got following error
Error in final launch sequence:
Failed to execute MI command:
-exec-continue
Error message from debugger back end:
Cannot execute this command while the selected thread is running.
Failed to execute MI command:
-exec-continue
Error message from debugger back end:
Cannot execute this command while the selected thread is running.
Cannot execute this command while the selected thread is running.
I was able to remove this by disabling the "set breakpoint at [main]" box in the debug configuration. The error is gone, but I have not tested if debuggin works properly yet.
Thank you so much for your videos. It took a while, but right now it feels worth it :)

I'm glad they helped you out!
thinking of it it most likely that break at main thing. I was trying to start the code before the verify command was done and got all sort of weird behavior. Trying to send the -exec-continue command while the thread is already running seems like asking for trouble :)

Hi everyone
I'm new on ST boards, I have followed all steps on this video https://www.youtube.com/watch?v=VOs2LYO7wSA&feature=youtu.be and this video to use quadspi https://www.youtube.com/watch?v=237lPdMsDZs&feature=youtu.be. When build my project it doesn't have problems but at debugging my board gets just a black screen. Any idea which I could doing wrong?

at the very least - you should have a white screen. If not, that could imply that you haven't configured the LCD_DISP pin properly in the MX configuration.

Thanks for Reply. Following the first video mentioned I created a new projet with default pin configuration as showed in video. I have tried with project in first video and it works fine (just two screen with a button each one). I copied MX_QUADSPI_Init code posted here to configure it. When enters in debug mode the screen is white but after run it get black. I checked Pins configuration with .ioc file and tried changing display type from RGB888 to RGB565 but still have back screen

I still have the problem, to give more details, I created a template project using TouchGFX copied code from .ld file about QUADSPI section as show you below and code in MX_QUADSPI_Init function.
MEMORY
{
RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 320K
FLASH (rx) : ORIGIN = 0x8000000, LENGTH = 1024K
QUADSPI (r) : ORIGIN = 0x90000000, LENGTH = 16M
}
and this
...
libgcc.a ( * )
}
.ARM.attributes 0 : { *(.ARM.attributes) }
ExtFlashSection :
{
*(ExtFlashSection ExtFlashSection.*)
*(.gnu.linkonce.r.*)
. = ALIGN(0x4);
} >QUADSPI
/* Un comment this section to place fonts and text in external flash*/
FontFlashSection :
{
*(FontFlashSection FontFlashSection.*)
*(.gnu.linkonce.r.*)
. = ALIGN(0x4);
} >QUADSPI
TextFlashSection :
{
*(TextFlashSection TextFlashSection.*)
*(.gnu.linkonce.r.*)
. = ALIGN(0x4);
} >QUADSPI
}
and
hqspi.Instance = QUADSPI;
hqspi.Init.ClockPrescaler = 1;
hqspi.Init.FifoThreshold = 4;
hqspi.Init.SampleShifting = QSPI_SAMPLE_SHIFTING_HALFCYCLE;
hqspi.Init.FlashSize = 24;
hqspi.Init.ChipSelectHighTime = QSPI_CS_HIGH_TIME_6_CYCLE;
hqspi.Init.ClockMode = QSPI_CLOCK_MODE_0;
hqspi.Init.FlashID = QSPI_FLASH_ID_1;
hqspi.Init.DualFlash = QSPI_DUALFLASH_DISABLE;
if (HAL_QSPI_Init(&hqspi) != HAL_OK)
{
Error_Handler();
}
/* USER CODE BEGIN QUADSPI_Init 2 */
BSP_QSPI_Init();
BSP_QSPI_MemoryMappedMode();
HAL_NVIC_DisableIRQ(QUADSPI_IRQn);
MPU_Region_InitTypeDef MPU_InitStruct;
MPU_InitStruct.Enable = MPU_REGION_ENABLE;
MPU_InitStruct.BaseAddress = 0x90000000;
MPU_InitStruct.Size = MPU_REGION_SIZE_256MB;
MPU_InitStruct.AccessPermission = MPU_REGION_FULL_ACCESS;
MPU_InitStruct.IsBufferable = MPU_ACCESS_NOT_BUFFERABLE;
MPU_InitStruct.IsCacheable = MPU_ACCESS_NOT_CACHEABLE;
MPU_InitStruct.IsShareable = MPU_ACCESS_NOT_SHAREABLE;
MPU_InitStruct.Number = MPU_REGION_NUMBER2;
MPU_InitStruct.TypeExtField = MPU_TEX_LEVEL0;
MPU_InitStruct.SubRegionDisable = 0x00;
MPU_InitStruct.DisableExec = MPU_INSTRUCTION_ACCESS_ENABLE;
HAL_MPU_ConfigRegion(&MPU_InitStruct);
/* Configure the MPU attributes as WT for QSPI (used 16Mbytes) */
MPU_InitStruct.Enable = MPU_REGION_ENABLE;
MPU_InitStruct.BaseAddress = 0x90000000;
MPU_InitStruct.Size = MPU_REGION_SIZE_16MB; /* NOTE! Change this if you change QSPI flash size! */
MPU_InitStruct.AccessPermission = MPU_REGION_FULL_ACCESS;
MPU_InitStruct.IsBufferable = MPU_ACCESS_NOT_BUFFERABLE;
MPU_InitStruct.IsCacheable = MPU_ACCESS_CACHEABLE;
MPU_InitStruct.IsShareable = MPU_ACCESS_NOT_SHAREABLE;
MPU_InitStruct.Number = MPU_REGION_NUMBER3;
MPU_InitStruct.TypeExtField = MPU_TEX_LEVEL0;
MPU_InitStruct.SubRegionDisable = 0x00;
MPU_InitStruct.DisableExec = MPU_INSTRUCTION_ACCESS_ENABLE;
HAL_MPU_ConfigRegion(&MPU_InitStruct);
HAL_MPU_Enable(MPU_PRIVILEGED_DEFAULT);
But checking memory on "Memory details", FontFlashSection and TextFlashSection are still on internal flash.
This is my pin configuration
And the pin mentioned on video "PI12"
And Still having black screen on debug.
A pair of things I have saw
* debug gets stuck for a long time on 93% after gets to main waiting for press button run.
* If something is modified and then genereded code; the first lines of configuration on QUADSPI init function are showed.
I hope this information give you a clue of what is wrong with my example project.
Finally I use four images as background some animated images buttons and texts

Hi everyone
Thanks for support, I have a working project. I did everything again and know my prototype is working. The only thing I could think is "some days ago my ide was updated and my project was been created by old version" so maybe this could be the error.

Hai bro Still I am working in QSPI concept in stm32f746 disco board
I tried to write the data for QSPI flash memory but I can't able to write and read the QSPI flash memory i need your help bro i have attached my code and snap pls find and give any sollution are example code
