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...
I am Korean and a developer with less than a year of experience. Please understand the immaturity of inquiring in the official English language. I am using STM32MP157C-EV1 board. The board has the following settings according to the blog link I refer...
Hello,we are working on the ST32MP1. The SPI3 works fine with the CubeMX software combining the DMA2 and FIFO when the board works in engineering mode. But if I perform the same software loaded by Linux (rproc start), the DMA2 SPI stream stops worki...
I ran into a warning for one section of code that I did not for a different section of code. So I simplified it into two function. I don't see why I get a warning for one and not the other.void test32(uint32_t *data) { uint32_t src_addr = (uint32_t...
