I've managed to configure the STM32 CRC such that it can create the standard CRC-32 as per this article - https://stackoverflow.com/questions/39646441/how-to-set-stm32-to-generate-standard-crc32. However, this CRC does not match Ethernet spec.Is ther...

I'm looking to control the CDC_Receive_FS interrupt in a manner that I'm hoping is supported by the lower level hardware, but I'm having difficulty locating registers and functionality to support this behavior.To give a hint to the architecture I'm w...

According to the OctoSpi Documentation, only one of the five phases needs to be active in order to configure OctoSpi. "20.4.3 OCTOSPI Regular-command protocol When in Regular-command protocol, the OCTOSPI communicates with the external device using c...

I’m attempting to optimize a process of loading a large file from eMMC flash memory directly into a SPI device with 8 data lanes. Originally, I meant to use peripheral to peripheral in the DMA component that comes internally with the STM32L5 series. ...

When trying to read/write to the connected eMMC device, the eMMC driver will sometimes fail with an error. After failing in this way, every call to HAL_MMC_ReadBlocks or HAL_MMC_WriteBlocks will fail until the microcontroller is restarted. If the fir...

Both CRC-32 in question are using a polynomial of 0x04C11DB7. I'm using byte input data inversion mode to handle the endian problem.My current configuration is on an STM32L5 hcrc.Init.DefaultPolynomialUse = DEFAULT_POLYNOMIAL_ENABLE; hcrc.Init.De...

I've just realized the "USBD_CDC_ReceivePacket" function from within CDC_Receive_FS() controls when new packets are able to arrive. So I can use that to control buffer overflow, and I can adjust the new buffer position with "USBD_CDC_SetRxBuffer" to...

Thanks @Imen DAHMEN, I hope it can get patched!

Hey @ChahinezC I'm using the OctoSPI peripheral to load an FPGA configuration. In this case, I was unable to find success with memory-mapped mode because of the FPGA timing and special data constraints. I did spend a solid week trying to get this me...

Hello @ChahinezC ,I'm actually going to have to apologize here. This was our mistake. The software driver became suspicious because the issue was caused periodically but only on the first call (All future calls would work without issue), and the d...
