Hi,I am using stm32WB5MM, I have bootloader which is located on regular start address 0x8000000.Bootloader executes image which is located on some other location (location is divisible by 0x400 as required).For that image I changed linker file and xx...
Configured the controller stm32l151c8t6a to work in low power run mode ( UART peripheral running) but the current consumption is going upto 6.2mA. After disabling the uart peripheral the consumption decreases upto 4.2mA. In real situation we are goin...
In "Memory Mapping" section of the datasheet, the SRAM2 Address is indicated as 0x2001-C000. The actual Address should be 0x2000-C000 since from what the reference manual says, both SRAM1 and SRAM2 are mapped at 0x2000-0000. AHB1 Bus address has a...
I was trying to change an option byte from the embedded bootloader of an stm32u5 over canFD. Long story short I sent it some messages that were not formatted correctly and It looks like I have bricked the chip. Trying to connect in stm32cubeprog wi...
Hello,I am assisting with the firmware development of a dual-active bridge converter and I am trying to create a phase-shifted PWM signal that will control the switches. Creating the phase shift is proving challenging, but I had an idea that I believ...
Hi,I'm working with a STM32F439 and I set both timers, timer3 & timer4 to produce a 460ns pulse at a 50Hz frequency with their PWM feature. Now I need to be able to control their offset to each other with the ability to set it to 0. But it appears li...
We have a STM32U575xx chip, where I want to read a bunch of voltages continuously.These voltages don't need to be measured at a particularly high rate, nor does the timing need to be strict. So it seemed efficient to run the ADC continuously with DMA...
Hello,I am using the STM32H7S78-DK board and STM32CubeIDE for development. In my application, I am working with UART communication between UART4 and UART7.Objective:I am sending data from UART4 (connected to the Virtual COM port on the board).The dat...

Hello,I'm just started using a nucleo-h742x. I have configured the SPI and the Fatfs library using the default settings, the SPI speed was configured at speed below 1Mbit/s. The sys clock is below 100MHz.I always get disk_not_ready error when trying ...
