Hi, I started working on my own dev board for a flight computer based on the STM32H747BIT6.At first, I struggled a bit to connect the board to the computer, only managing to do so using the hot plug mode in order to get some info from the microcontro...
I am having issues with Ethernet+LwIP+FreeRTOS on the NUCLEO-H7S3L8. I was able to get Ethernet+LwIP to work on baremetal, but adding the RTOS and threading is having issues. I have attempted to follow the process here, but am still having issues. ...
MCU：STM32G070CBTx LQFP48My question is as follows: Why is it necessary to execute HAL_ADCEx_Calibration_Start() to calibrate EO and EG before using the ADC?Why isn’t this calibration performed at the factory before shipment?
Hi,I am facing issue with bootup in stm32h745xih6 controller. I am able to initiate debug for CM7 but when I initiate the same for CM4, in that case CM 4 does not go in debug and it fails and following error in there:<terminated>MOSv1.2_CM4 Debug [ST...
I bought the STM32H750B Discovery and wanted to program a first example "LTDC Paint" on the demo to start. I am using the STM32Cube IDE version 1.9 (default installation, no changes made).Procedure:- File -> New -> STM32 Project -> Examples -> select...
My understanding is that when setting BFB2, Bank 2 is remapped to 0x0800 0000.Why should we need to set VTOR on reset if thanks to remapping it should interact the same?Meaning I expect the start of my vector table for app2 to be at the same address ...
Hi, Please help me sort this out.I am trying to port a custom bootloader originally written for the SAMD21 Arm chip to the STM32U385VGT6. We are upgrading our current product with an STM32 Chip. I am having problems with switching from the bootloader...
After configuring SPI1 in CubeMX and calling HAL_SPI_Transmit, I get a signal on the SPI1_MOSI line, but no signal on the SPI1_CK. I have confirmed that the pin is working correctly with other code and tried different clock speeds to see if that was ...
When we were working on a small batch, we encountered a situation where one of about 100 pcbs would frequently trigger a hardfault. We found that the problem would recur when the cache was enabled. When the mpu was enabled and configured correctly, i...
Heyho,just checking the L162 for a new project, then found that the ADC can only be clocked by the HSI.Is that correct?If yes, why?My experience with HSI (and other RC-oscillators) is that it is "mediocre" at best, rather inaccurate and jitters like ...
