Resolved! STM32F4 can I join SRAM and SRAM2 memories?
Hi, I have STM32F407VET6 which has such memory layout.Can I join SRAM (0x2000 0000 - 0x2001 BFFF) and SRAM2 (0x2001 C000 - 0x2001 FFFF) memories to one?Or do I must to manage them separately?

Resolved! [STM32H7B0][OSPI] Not able to activate Memory Mapped mode in Read and Write modes
Hello Dear Community,I am having a real strange issue while using OSPI peripheral in STM32H7B0 custom board.I am trying to use OSPI with PSRAM but I wanna make sure it works fine, so I am using it with a NOR Flash for test.When I try to activate the ...
Incorrect footnote for pin capacitance in I/O port characteristics table
This is how footnotes looked like in old rev of the same DS:i.e. the "hysteresis" footnote goes to Vhys, and Cio should have a separate footnote.I've seen this error in several 'F4 and 'F7 DS.JW
STM32U575 change PWM output duty realtime
I tried to change PWM output duty without stopping or suspending PWM output, but between two times of writing new value to CCR, there must be a delay time inserted in. Following is the example code:/* if delay_ms(300), code can run correctly, if chan...
Using the FMC of the STM32U575 for SDRAM
Hello everyone,I am currently working with a STM32U575ZIT6 and am trying to connect as much RAM as possible to its FMC peripheral. However, SRAM and PSRAM are not available in the sizes I am looking for, so I was wondering if it would be possible to ...
Data acquisition from PDM microphones via SAI using DMA - problem with writing to PDM_buffer
I have configured the readout of 4 PDM microphones through the SAI interface. I am using 1 slot of 32 bits per frame. I have enabled DMA.Unfortunately, when reading PDM data, the first 6 and last 2 values of the array are filled with zeros. This happ...
1. SPI communication between MCU and MPU.
Hi,I am working on SPI bus communication between IMX6dl MPU and STM32L476 MCU.MPU work as a master device and MCU work as a slave device.Configuration of MPU is:pinctrl_ecspi3: ecspi3grp { fsl,pins = < MX6QDL_PAD_D...

Problem using STM32F411 ADC,DMA, USB virtual com and HAL_ADC_ConvHalfCpltCallback
Hello everyone, I'm trying to develop a simple DAQ, most of the code is generated by stm32cubemx then I just added two callback (HAL_ADC_ConvHalfCpltCallback and HAL_ADC_ConvCpltCallback) to send the half buffer data by the USB virtual com, pretty s...
Is there somewhere to write custom data that isn't overwritten by the bootloader?
I want to be able to program a STM32H7 device with something like a device ID, for example, this device is #10, and that devices is #55. This would affect the behavior of the device, so it must be possible to read that number through the firmware, so...
