I have a strange issue. I used the SDIO Interface on a F2 and a F429 without issues. But on the first usage with the F446 i run into a strange problem.With the Logic Analyzer i am observing the communication.Card Init:Requesting Card Type, CSD and CI...
I'm not able to conclude the FreeRTOS demo application for the B-L475E-IOT01A2 board. I'm following the instructions given in FreeRTOS User Guide.After compile and upload the firmware to the B-L475E-IOT01A2 board, two sort of problems are happening:1...
Hello,I'm testing with a NUCLEO-U575ZI-Q, I'm testing with the examples STM3Cube_FW_U5_V1.1.0.0jects_NUCLEO-U575ZI-Q. The minimum consumption I have achieved by modifying the code somewhat is 118uA seems very high to me.With other models of NUCLEO I ...
Hello everyone,I have a device based on a STM32H753ii which has an USB-OTG interface that is used for both serial communication and for mass storage mode. This last one is to have access to an EEPROM that is also on the same PCB.Normally, if we build...
What is the effect of USBH_MAX_DATA_BUFFER ? If I increase the value of this would it make my USB read faster ?

Hello USBH_MSC_Read function uses a while loop and USBH_MSC_RdWrProcess to USB mass storage. while (USBH_MSC_RdWrProcess(phost, lun) == USBH_BUSY) { if (((phost->Timer - timeout) > (10000U * length)) || (phost->device.is_connected == 0U) ) ...
I have used DFU USB to program hundreds of STM32F7 devices over the past several years. It has worked reliably until the most recent batch of 200 boards using STM32F&56VGT6 devices. We had approximately a 10% failure of the DFU USB connection (USB no...
Per section 2.6 of RM0433 (https://www.st.com/resource/en/reference_manual/rm0433-stm32h742-stm32h743753-and-stm32h750-value-line-advanced-armbased-32bit-mcus-stmicroelectronics.pdf), when the STM32H7 boots up it latches the boot pin and then goes to...
Hi,I use STM32H7+LWIP+FreeRTOS. With using STM32IDE and this forum I can now ping to my board from PC and get answer - perfect.Now I want to send and recieve some UDP packets - I can browse the code and try to understand how it all works (how to TX/R...
