Hello,I'm currently tring to do an app and I want to switch in unprivileged mode when I'm in secure and privileged mode. The switch is working but the uart is not working in unprivileged mode. It works in privileged mode. When I debug my code go in t...
Hi, after spending already the half day, i finally found one problem of multiple:https://github.com/STMicroelectronics/cmsis-device-g4/blob/master/Include/stm32g431xx.hLine 1029 continues with wrong offset. Should be 18. Following are wrong too.After...
Dear community, my Nucleo H723ZG captures analog signals via channels (see attachment) :ADC12_INP15,ADC12_INP10 andADC12_INP10 The second one reads a 4-20mA pressure signal from a sensor with the help of an external shunt resistor. After a system res...
If Systembootloader Doesnt detect anything comming from any peripheral, does it timeout and jump to 0x8000000?Because by reading AN3154 , it looks like it does, but when im trying with my stm32f405RE it doesn this is my code: int main(void) { /* ...
Posted on January 12, 2015 at 09:17HiI am using STM32L151 bootloader.I wanted to run the bootloader at program start, and if no usb if attached for a certain timego back to regular application.Is it possible to configure a timeout for the bootloader...
when I use the usart6's DMA, my SDIO can't write to the SD card properly
Hi all. I am using STM32H747BIT6 with cm4 & cm7 cores but I am struggling with debugging my application. I started a new STM32 project using the CubeIDE wizard and gave the ioc file to generate simple code. Then I built the two projects (m4 & m7). Af...
If my data is more than one 32-bit word and I have to write it one 32-bit word at a time to the FIFO, is it possible that the USB controller could send just the first 32-bit word? Is there a way to stop that from happening?Thanks```USBx_DFIFO(1) = se...
Hello folks I am using the first bank for the firmware and the second bank to save a bunch of parameters. When the fw receives a command via uart, it updates the parameters erasing first and then writing groups of 8 bytes. When I try to erase the fir...
I am doing an academic activity where I was asked to execute a reading process from an external RTC via i2C, but on another MCU, I used a repeat timer, but I was unsuccessful. Something seems to interfere with the I2C communication and according to ...
