STM32H7 and openbootloader
Hi I'm implementing Openbootloader to my project, using an STM32H743, and is having a hard time finding the correct start addresses and size for "Option bytes registers". This is needed to in the "openbootloader_conf.h" file in the Openbootloader mid...
Resolved! FMC SDRAM common clock description mismatch between CubeIDE and RM0433
I want to set up 100MHz for SDRAM.STM32CubeIDE version 1.18.1 has the following options for SDRAM clock:The selected board is the STM32H743IITx. RM0433 Rev 8 states that:I'm not sure HCLK and fmc_ker_ck are the same thing.If I have my FMC clock set u...
Resolved! STM32U5 workshop GPDMA on U5A5
I followed the GPDMA tutorial here:https://www.youtube.com/watch?v=jKOhRfb3gvkand configured everything as shown. The workshop was on a U575 but I would assume it's the same configuration for the U5A5? I'm using the Nucleo-U5A5ZJ-Q. I'm unable to ...
Resolved! STM32F401RETx HardFault in HAL_Init() for TIM4/TIM5 Timebase source
Hello! I'm working with FreeRTOS for the first time and am getting a HardFault during the call HAL_NVIC_EnableIRQ(TIM4_IRQn); call inside of HAL_InitTick(); from HAL_Init();I am currently testing with a Nucleo board with MCU STM32F401RET6U and have c...
Resolved! Which internal temperature is correct in STM32Cube FW_G4 V1.6.1
I want to use Macro "__LL_ADC_CALC_TEMPERATURE" to calculate the chip's temperature. But there is a difference here. As mentioned above, in datasheet, TS_CAL2 corresponds to 130 ℃.But in STM32Cube FW_G4 V1.6.1, file "stm32g4xx_ll_adc.h", line 386, T...
Resolved! Floating-point arithmetic interrupts
Hello to everyone in the forum. I am using STM32H735.Is it possible to perform a floating point number operation and generate an interrupt when an exception occurs?I want to interrupt when the bit for exception generation in the FPSCR register is tur...
HSEM causes weird jitter
Hello,Has anybody experienced weird jittery like behaviour when using the HSEM between two cores on the STM32H755 or another dual core MCU? This is the logic right now:The CM4 has a 1 kHz loop that toggles a GPIO on each successful reception of data ...
