Memory Management in STM32 || Cortex M7 || CUBEIDE

[@ControllersTech]

Please don't ask me about other IDEs like Keil or IAR. I don't know about them.

[@bobby9568]

No problem, what you are using is just fine. Just like always amazing content, you are very smart!

[@vigneshwaransaminathan6418]

Sir, this IDE is powerful than others. Whatever the things we do in keil, seggar we can do here in cube IDE as well. Continue your great job.

Hey can we have a tutorial where u teach how to use external flash like the WQ25xx series in SPI mode or QSPI mode?? Waiting for reply!!

[@ControllersTech]

Later.. first i need to cover MPU. Without that use of external memories will be useless.

[@ecs038_ark7]

I will be waiting patiently 😊

[@filiprak1184]

So important topic for bigger projects. Thank you very much! Looking forward for the next part :)

[@wolek141]

Such an awesome explanation of the topic, i am really thankful for your job!

[@lucvanhove9639]

Thanks for this info, I'm new with STM32f7, so different with PIC 👍😃

[@excite236]

You will love stm and their ecosystem.

Thanks for the video, very good as always. I have a couple of questions: In case we makr a change and regenerate code with cube mx would the changes on the linker script be overrided? Also, will there be any tutorial focusing on linker scripts? Thank you so much!

[@ControllersTech]

1. No the linker script won't change with regeneration. 2. No plan on making any particular video for it. This is it for the script part.

@@ControllersTech Thank you very much! Keep up the amazing work

Thanks a lot! What an amazing free material...

12:16 - In the Memory Details tab, why is the LMA column empty? In my case I am getting confusing readings. The (VMA) seems to be matching the number in the Ethernet Buffer configuration, which to my understanding were the physical address of the memory. Are the address in the Ref Manual the ones that should show in LMA?

[@mikegomez70]

Hi CT! this is pure gold! Thank you! Is it possible to pointer a buffer in an external sdram?

[@ControllersTech]

Yeah sure, why not. That's what the external memories are there for.

[@mikegomez70]

@@ControllersTech Many thanks! (Y)

Great video, thank you controllers Tech

[@mateusgomes3617]

Hi, great work. There will be a video about how to setup STM32 SPI in slave mode using registers ? Im struggling with HAL functions and DMA.

[@saustin98]

Great video. What are you using to display the manual? I like the way it's laid out.

[@ControllersTech]

Okular pdf thingy

You put so much effort into these very useful videos but so far I have not been able to run anything on a Riverdi (STM32H747) platform (except for the high-level generated TouchGFX GUI). I have tried to modify such projects by adding some simple functionality by adding a DAC that is timed by a timer and fed from the DMA based on one of your related videos, but this video got me thinking that it failed because the memory was in a wrong location. However, I have tried to replicate what you have done, simply declaring a variable in the main.c file (tried with both for M4/M7 core) and I cannot even see the variable in the build analyzer's memory region, let alone after modification of the .ld file and adding the section directive!!!. Do you know what could be wrong there, maybe some memory protection? But mind you, this is still only the build state and nothing had been downloaded...

[@woldecosgrove]

Hello i have been following your video and would like to know if this tutorial can work on STM32H750 Discovery board, this is the only board i have now.

[@ControllersTech]

Yes it works for all m7 devices.

[@armenian34]

perfect demostration...

[@kaziasifkhaled1751]

Thanks for the video. I have one question. When you changed the memory location in F746, although the address of the variable changed, but the RAM usage was substantially higher (20.63%)! Is it normal?

[@ControllersTech]

It depends on the usage and size. And yes it's normal

[@Saranbabu05]

Hello sir, Thanks for the video. Keep up your good work. Please make a video for project creation in cube IDE along with touchgfx. I'm eagerly waiting for this video.

[@ControllersTech]

not a fan of touchgfx.. I will make for the lvgl though

I really love your videos. Can you please make a complex CAN network with STM32? with 3+ tx messages and 3+ rx messages. I don't find any tutorial about that 😭

[@ControllersTech]

Yeah i am thinking about it.. but it will take a while. There is already a lot in my to-to list.

@@ControllersTech Thank u for reply ☺️

[@shettymalnad1978]

Hello sir i am stuck in linking DMA to ADC any related videos or any guidence .

[@ControllersTech]

Check mpu config videos in the cortex m7 playlist. There are about 4-5 videos i guess.
