Creating a non cacheable area of RAM on STM32H7A (B)
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...
Trusted Firmware-M for STM32U5 or STM32L5
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!
Data storage on cloud using STWINKT1B
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?
How to solve HardFault or MemManage Handler for STM32H743?
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...
How Segger J-FLASH configures its external loaders?
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 ...
Why does MemManage Fault occur in ITCM?
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
Need libraries for MCP4261 digital potentiometer
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.
Resolved! Why do I miss certain things when breakpoint and single stepping functions (e.g. in CRYP or I2C)? Is there anything I can set to help this during debug?
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.
Is the compass demo available for the STM32F303? It looks like older boards came with this but the new one uses the gyro instead.
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 ...
