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.
