Hello,My app running on M4 uses adc. It starting at kernel boot process using systemd. After some time kernel poweroff vdda and vref while my app is running[ 14.173564] remoteproc remoteproc0: powering up m4[ 14.308543] remoteproc remoteproc0: Boo...
Hello,I'd like use several gpio buttons to onboard CN2 connector (STM gpios PF0, PF1, PF3, PF4, PF6, PF8). So I've add following string to stm32mp157c-dk2.dts filebuttonkeys { compatible = "gpio-keys"; left-key { label="Left key"; ...
MCU is STM32F405. I write data array to output pins using DMA mem to peripheral (DM2 stream6 channel0). Trigger is TIM1 CC1 event. Also I use DMA2 stream5 channel6 for write to TIM1 registers. Trigger is TIM1 UEV event. So the writing and interrupt D...
Posted on January 16, 2018 at 11:32Hello,I use STM32L452 QUAd SPI for communicate with Winbond w25n01g NAND Flash.My init code ispage = 0x30; /* Initialize the read command */ sCommand.InstructionMode = QSPI_INSTRUCTION_1_LINE; sCommand.Instruc...
Hello Patrick,My dts files include all defines described your link but vref & vdda disabling by kernel. If I run m4 app after this disabling adc works fine (so app enabled vref and vdda).PS: I've changed regulator-boot-on to regulator-always-on in dt...
If I pullup these gpios using external resistor they work fine. In case already used by some internal peripherals the ones shouldn't work at all, right?Thanks,Alex.
Hello Olivier!Thank for your advice! Unfortunally combination GPIO_ACTIVE_LOW and GPIO_PULL_UP and path gpiolib.c driver help only for PF0 and PF8. Unpressed PF3, PF5, PF6 and PF9 still are cause to occure for multiple events. If I pullup these gpios...
