Resolved! Do STM32F401 and F411 have a CCRAM ?
The documentation of these specific MCU do not show the CCRAM in the memory map.From my understanding this is Cortex-M4 related...https://github.com/ObKo/stm32-cmake/issues/134#issuecomment-651631813

STM32F103 unique device identifier not found (response ffffffff)
Hi,I have an issue with STM32F103RCT6 MCUs. When trying to check the device unique identifier sometimes (about 5% of the chips I tested) the response I get from the chip is just:ffffffff ffffffff ffffffffinstead of a "uuid-looking" 96-bit hexadecimal...
PWM+DMA behavior differes on STM32F407 compared to STM32G474
I tried to generate a 2-channel PWM on both the STM32F407 and the STM32G474. I was surprised to see that the PWM of both channels started simultanously, while for the F4 there was a delay. Is this intended behavior? Is there a work-around?This is fro...
memcmp crashes when accessing data stored in flash
STM32H745ziI am storing some configuration data in flash memory at address 0x080E0000.If I call HAL_FLASHEx_Erase and then do a memcmp of 24 bytes at this address vs a buffer where I have prepared data I want to write there everything is fine althoug...
Resolved! i would like to know how linker commands can be used in source file to push the multiple structure defines into a part of code memory. can some body share with examples
steps i tried.step 1: created a section in linker file ".parambuf"step2: in source file declared a structuretypedef struct{ param_t param[256]; \} t_param_block_t;step 3: in header files using attributes commands to push into parambuf section.extern ...
Resolved! STM32F7 + QSPI (QUADSPI): Sporadic failure with memory-mapped flash memory. Disabling timeout does not help.
Hi everyone,We have an issue when using QUADSPI (memory-mapped) on a STM32F7 microcontroller. The controller sporadically runs into a watchdog reset. Investigation showed that the crash always occurs during a LDM instruction from the memory-mapped fl...
Resolved! What STM32 Microcontroller will fit me
I am trying to make the transition from Arduino/Atmel micro controllers to something that can support true threading/multitasking in the 32bit ARM processor category. I am making a robot where I need to control 7+ 12v motors, 24 servos, 100+LEDS, spe...
Problem Porting TLS CLient from F207 to H743
I managed to get a simple TLS client working on the NUCLEO-F207ZG. I cannot get the program to run on the NUCLEO-H743ZI2. On Wireshark I see several DHCP DISCOVER messages go out; followed by an OFFER message coming back. My code never responds with ...
Do SPI pins ever float?
When I used buffers between CPU and SPI peripherals I got problems. There were no Pull-ups.Bare GPIO pins with pull ups work. So do SPI pins float between transfers?CPU happens to be STM32H750/STM32F746 if it matters.
