STM32G0B1RETx DFU design questions, BOOT0
Setup: I am designing on the Nucleo-G0B1REGoal: DFU via USB FW updatesAlthough the Nucleo Expansion provides a USB ST-Link interface I do not want to utilize this interface as I want to go directly to the MCU to emulate our board.For code uploads an...
Resolved! USB host HID LS chirp issue?
Hi,I have a USB host HID FS/LS on a nucleo board (also on definitive hardware this happens). It works with several keyboards (Logitech, Acer, china trades, ...).Today, I connected an HP slim keyboard 803181-071 SP provided with my computer and after ...
Resolved! STM32H743XI SDMMC1 SD Card - HAL_SD_ERROR_UNSUPPORTED_FEATURE
Hello,I'm currently facing an issue with a basic project to setup the SDMMC1 peripheral where the function HAL_SD_Init() fails. The issue is happening inside HAL_SD_Init(), in SD_PowerON(), where it always returns HAL_SD_ERROR_UNSUPPORTED_FEATURE. I...
The STM32F469 has the USB bugs found in errata of STM32F429 (but not its own errata) where it can't connect to low-speed thru a hub. Is that a problem in the PHY, and will using an external PHY solve it?
Specifically, will using the STULPI01 allow a low-speed device to connect via a hub to the OTG-HS USB interface, or is this bug not actually in the internal FS-PHY, but in the controller?
AZURE vs FreeRTOS
On the newer chips, such as the U5 series, FreeRTOS support is underwhelming in CubeMXIDE. I have, and did, use FreeRTOS. I tried AZURE in a C++ programming environment and found several problems, one to do with systick, another to do with tasks, o...
UART DMA receive to Idle with LL
Hello all,at the moment I use the HAL function HAL_UARTEx_ReceiveToIdle_DMA to receive the data from the UART. This works very well but I have a timing problem because I want to send and receive a lot of bytes. To speed this up I want to use the LL f...
Move/change default reset location of STM32F765
We are trying to implement application which starts from location(eg. 0x0806 0000 of the flash) which other than default 0x0800 0000.As per STM32F765 reference manual and AN2606 performed following steps,Switched to Dual bank mode of flash, nDBank = ...
