Does anyone have experience with Etherner/IP on STM32? (STM MCU or MPU are just fine)We are looking for Ethernet/IP example on STM32 but seems not found any thing yet.All we found are just : I-NUCLEO-NETX - netSHIELD industrial ethernet protocols exp...
Hi, we see STM32H7 has Qspi errata as below: But we are not sure where to apply the patch exactly. It says "upon reset and upon switching from memory-mapped", mean in reset function, right after or before "HAL_QSPI_Init"?
Hi, on SPI, does anyone know why every 8 bytes then it has a big gap?We tried:1MH, no gap,2MH, gap occurs,4MHz gap bigger,8MH gap bigger than 4MHzSeem higher frequency, bigger gap We don't use DMA
I am using STM32CubeMx to generate device tree:I got these in uboot device tree:&rcc {st,clksrc=<CLK_MPU_PLL1PCLK_AXI_PLL2PCLK_MCU_PLL3PCLK_PLL12_HSECLK_PLL3_HSECLK_PLL4_HSECLK_RTC_LSECLK_MCO1_HSICLK_MCO2_DISABLED>; st,clkdiv = <1 /*MPU*/0 /*AXI*/0 /...
Hi, I set MCO1 using HSE clock and get 8MHz working well (my HSE is 8MHz)But I need 16MHz or higher on MCO1, so I changed to MCO1 source clock by HSI but there is nothing.I tested other CSI, HSE, ... MCO1 work, except for HSI.I think there is somethi...
Hi, thanks for quick reply,I think you are mentioning about Ethernet, LWIP, and this is not what we are looking for.We are looking for EtherNet/IP. This is an industrial network protocol that adapts the Common Industrial Protocol (CIP) to standard Et...
Following @KDJEM.1 : "before enabling peripheral clock and after HAL_QSPI_Init()."Following @Tesla DeLorean : "prior to HAL_QSPI_Init(), but after the APB ENA / RST for the peripheral/clocks"Following the ST HAL Driver: enabling peripheral clock is i...
Thanks PatrickF,I got dma working with resolution higher than 320x240. Problem was, I am using old kernel that using dmaengine_prep_slave_single while new version use dmaengine_prep_slave_sg. But I still have one more problem if you know or have any ...
Hi, I have same issue, capture 480x272 or smaller seems find, but higher then I have same error message:""dma dma0chan2: nb items not supported" and "stm32-dcmi 4c006000.dcmi: dcmi_start_dma: DMA dmaengine_prep_slave_single failed for buffer..." did ...
