Using the linker script - How would I assign an area of AXI SRAM1 that is not cacheable by DCache? I am currently having problems with DMA transfers to the PWM peripheral when DCache is enabled (I think this is because I am sending 8bits to the HAL_T...
Hello，has anyone run TF-M successfully on STM32U5 or STM32L5 ? Does ST provide examples for this? I have NUCLEO-L552ZE and NUCLEO-U575ZI board.Looking forward to your reply!
I know that there are firmware files to store data on sd card but i just wanted to know if there is a way to store raw sensor data on the cloud directly using the board?
Hello,I have implemented some source code on my original borad with STM32H743.(ex. use HAL_UART_DMA, HAL_SAI_DMA, and more.)I run without Breakpoint, but HardFault occurs.However, I run with Breakpoint, HardFault does not occur.According to the Fault...
A customer has a board with STM32F746 and QSPI flash.The board looks as derived from STM32746G-DISCO, though I'm not 100% sure.Their program has data in the QSPI flash, and they flash the app using J-LINK and Segger J-Flash.Now, I cannot figure out ...
Hi,MemManage Fault occured in ITCM when I changed the system clock and DMA channel.Does ITCM cause errors? What are the causes of errors? Any ideas?I changed below:system clock: 480MHz→400MHzDMA: DMA2_Stream1 →BDMA_channel0
I am trying to interface Microchip MCP4261 digital potentiometer with my STM32F401 based Nucleo-64 board.. Can somebody share the libraries for the same? Thanks.
An example is while( (I2Cx->SR1 & I2C_SR1_ADDR) != I2C_SR1_ADDR)breakpoint on this line means I loop indefinately, breakpoint before and after and it reads ok?I'm using EWARM.
I am building a test stand for motor stators. I planned to energize coils and use the demo compass to check coil identity and polarity. Just looking at the indicator would be sufficient but it may be useful to read the magnetometer via USB.I think ...
Hello Everyone,I would like to ask you if you have any more information about an issue I'm incurring in.I am trying to setup a project on a custom board with the forementioned MCU, on which I need to use the first 4 SPI interfaces with DMA for quick ...
