We are trying to use circular DMA to transfer data from ADC1 into a buffer in MCU SRAM using CubeMX-generated code to configure the ADC and DMA. The DMA stream encounters a transfer error on transferring the first item. I have tried clearing the DMA ...
The RTC clock is on motherboard and usesthis driver (M41T62). I obtained source code from your website. I try to compile this driver as a linux module (debian). I have learnt that this driver is not supported.
Hi, I downloaded the image file required by STM32MP157-EV1 from Yocto, but this error occurred when I used ST32CubeProgrammer. Does anyone know how to solve it?Error:Yocto image information:
I tried setting the i2c frequency to less than 20KHz but I got the following error:[ 1.788573] stm32f7-i2c 40012000.i2c: no solution at all[ 1.792517] stm32f7-i2c 40012000.i2c: failed to compute I2C timings.[ 1.798793] stm32f7-i2c 40012000.i2c:...
Hi,we are working on a sensor data reading application based on your logic analyzer example project. But in our use case the data are sampled on a FPGA connected via QSPI. We have hard realtime requirements (far below 1ms) of reading the data and tra...

Hi, I am using my custom SOM board based on STM32MP157CAC3 chip. The DDR, SDMMC1, UART4, I2C4 & PMIC configuration is same as of stm32mp157c-DK2 board. even I have used the same pin configuration in my hardware. For USB OTG, I have left USB ID and US...
Hi,I am working on a custom board based on STM32MP157F and I am having some issues with USB and EHCI driver in U-Boot as well as with USB and OTG controller in U-Boot and TF-A.Once Linux is booted USB with EHCI driver works fine, but in u-boot it doe...
hi,i would like to know if there is an API for configuring, starting and stopping the timers (TIM1, TIM2, etc.) i'm interested in setting up a timer as a PWM device. i've come across documentation that talks about functions that can be used to set ...
I would like to configure USB_OTG_HS port as Virtual COM Port(VCP) on stm32mp157f-DK2 board. The board is running STLinux and the host is windows 10. I can see the debug usb port as COM6 on my windows-10 device manager - that works fine. I would li...
