Hi everyone,
On STM32C0, PA9 and PA11 are same pin, need to enable/disable remap to switch between them.
Meaning if I enable PA9 then PA11 cannot be used.
Same issue for PA10 and PA12.
In STM32 Bootloader mode, STM32 can detect UART or USB mode on th...
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 /...
That is not true or I am confused. From the organigram, if UART has not received 0x7F then check USB cable connection, if USB cable connection is not connected then back to check 0x7F, they are in loop.My question is how to check USB cable connection...
No, problem is still there, I tested on LQFP64 version which is PA9, PA10, PA11, PA12 are separately, on small version 28 pins still have problem, not sure how we detect usb cable.
