Hi,We wish to add CRC16 checksum to our communication payloads,and I see in the stm32mp157 datasheet CRC module section that it should support CRC32,16,8 and 7 bits."""25.4.3 CRC control register (CRC_CR)Bits 4:3 POLYSIZE[1:0]: Polynomial sizeThese b...
Hello !I have some trouble implementing a FDCAN internal loopback on the STM32MP157c-dk2.I have linked the FDCAN1 Instance to the cortex M4 and I don't have any can bus to connect it to yet so I'm trying to implement an internal loopback. I took the ...
Hi , iam using STM32mp157C micro processor ,On the cortexM4 i have configured SPI 1but iam unable to transmit using HAL_SPI_Transmit(), i have done some debugging in the spi driver , i found it is always returnning the HAL_TIMEOUT from SPI_WaitOnFlag...
Hi everyone, I am using stm32mp157f-dk2 with ecosystem 3.1.I am interested to store the board information of my future product using the OTP featureAfter reading the reference manual, ch3 and 4, I have the following doubtDo I need any extra hardware ...
stm32mp157daa boot linux is slow. it will take 15S in yotco rootfs. stm32mp could not fast boot ? it too slow.
hi I wanted info if there is a seminar or a course, or an expert person who can direct me to use the stm32 mp1 board really to take the first steps, in the area where I live near Parma Italy, thanks
Since STM32MP157D requires positive analog input, I have added a fully differential amplifier to capture the negative inputs. STM32MP157D devices embed two analog-to-digital converters.I have attached a diagram that explains my problem. I need to cap...
Hi, I have compiled the kernel source files and prepared the install artifacts as described in README.HOW_TO.txt, but when I am copying the modules into my STM32MP157C-DK2 board, it gets out of space. Moreover in the board I only have the modules rel...
I have custom board based on STM32MP157AAC3T CPU. I'm building image using yocto and board boots fine. Compared to devkit I'm using other panel .I've added driver + dts changes but I figured out that DSI drm driver is not probed. I checked dts on run...
Hi everyone, @Kevin HUBER I am using stm32mp157f-dk2 with ecosystem 3.1, with weston support.I connected the HDMI display to the development kit, reset the device, but nothing displayed.After checking, modetest show that the HDMI are properly conn...
