Hello all, When I had a beautiful STM32U5 in hand the world was still good.But now I have a comprehension question about the STM32L0, I have an 8-bit buffer and now the fastest way to AES decrypt/encrypt this data is via DMA with active burst mode. T...
Hi,I want to know a properly way do to that.If i use standard configuration I run hard fault as soon as DMA start (linklist mode) (HAL_HASHEx_SHA256_Start_DMA).I put Fault Analyser details Source/Destination secure bit are set before calling this fu...
I'm running SPI with DMA and CRC enable between two stm32, slave is stm32f415 MCU.Sometimes it appears that data received is corrupted whereas CRC check gives no error. For instance (polynomial used is 0x1021)Normal behavior:3 words sent: 0xAAA0; 0x0...
Hi,I want to compute APP's hash (SHA256) from my Bootloader using DMA.I have 3 non adjacent zone to process the HASH.If I use one node and call HAL_HASHEx_SHA256_Start_DMA inside HAL_HASH_InCpltCallback, I can compute my HASH.I hope I can use link li...
I'm struggling to get the SPI CRCERR flag and IRQ to work the way I expect.I am using an STM32WB55. The SPI communication in full duplex is working. The master is adding the CRC to the end of the Tx data. On the slave side, the CRC is read in. I can ...
Hi there.I'm struggling with the implementation of continuous SPI data transfer in Transmit only master mode with DMA in circular mode and enabled CRC calculation.In any other configuration I've tried (DMA normal mode or SPI transfer with MCU polling...
I'm attempting to configure peripherals in STM32CubeMX, but I'm getting error_handler calls from my DMA configuration for ADC1.All the necessary peripherals (DMA1 channel1, ADC1) are configured as secure in CubeMX, but when HAL_ADC_MspInit attempts t...
I need to receive SPI data from STM32G474RE master A to STM32G474RE slave B with DMA and CRC feature. DMA works in normal mode both on master and slave, which triggered by timer 2 on master A. The structure of the data frame is ADC1(16bit)+ADC2(16bit...
RNG, CRC, and DMA are all peripherals on the STM32L08x AHB bus. If I try to write to CRC_INIT before enabling CRC clock in RCC then STM32-WorkBench Memory window correctly just shows zeroes. But after enabling CRC clock in RCC_AHBENR and writing to C...
hi,my type is stm32f031, i try to debug ' spi + dma + crc' mode. i have no idea about transmit crc .i just enable crc_en, and set the bit crc_next every sending 8bit value.my logic analyzer occured the only 8 bit datas, it not contains the the crc va...
