Hello ST Community,I was following below link,https://wiki.st.com/stm32mpu/wiki/How_to_integrate_AWS_IoT_Greengrass_on_top_of_openSTLinux_distribution#cite_note-3I found that I have to buy STPM4RasPI extension board.The board is not available on mous...
Hi STI have a question when setting the ADC Clock on the M4 Core side.The STM32MP151C datasheet states that the ADC Clock can be set up to 36Mhz.When the AHB clock is 200Mhz, what clock will it work with if I set "ADC ClockPrescaler" to "ADC_CLOCK_SY...
what does MPU_InitStruct.TypeExtField ? mean only three options available #define MPU_TEX_LEVEL0 ((uint8_t)0x00)#define MPU_TEX_LEVEL1 ((uint8_t)0x01)#define MPU_TEX_LEVEL2 ((uint8_t)0x02)does it mean only 3 set of HAL_MPU_ConfigRegion(&MPU_InitSt...
We have own MP157 based module and it sometimes hangs after NRST during debug. It doesn't respond to JTAG DAP, further NRST pulses doesn't help but NRST_CORE helps. It seems as errata "Incorrect reset of glitch-free kernel clock switch". We tried sw ...
dts:in M4:I find the SPI1 doesn't work.
