Hi, I am working on STM32C071 I wrote code to jump to ST bootloader from my application. The code seems to work well, after jump to ST bootloader, I can connect to ST Bootloader by USB, using STM32CubeProgrammer. I can read flash data, option byte......

We are working on STM32C071KBU6 In STM example TIM_DMA, I see it uses PA10 - TIM1_CH3 with DMA channel 5, but I could not find anything about this. Anyone know how to find this information? I would like to use different pins but don't know what DMA c...

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, thank you for your reply, I tried enable interrupt but still don't work.My code is from your link actually, and it does work to jump ST bootloader. Problem is after jump to bootloader, all thing I can do just read, can't change for write to flash...

yes, LL_DMAMUX_REQ_xxx is input, that defined in table 42.But I don't know why it is LL_DMA_CHANNEL_5? That is main question. LL_DMA_SetPeriphRequest(DMA1, LL_DMA_CHANNEL_5, LL_DMAMUX_REQ_TIM1_UP);

That is the one I posted earlier. Table 42 saying input 22 for tim1_ch3_dma. That is it.The code I posted here, nowhere to use "input 22", and it is working fine. Input 22 is useless in my code and table 42 is not an answer.

Can you a bit more specific? Here is a piece of my code and I already get it working on PA1 which is TIM1_CH2 I understand input 22 is TIM1 channel 3, 21 is TIM1_CH2, but my code, I don't need to know this number. All I need to know is channel to set...

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...
