I'm using FatFs on an STM32F722 with Cube V1.12. FatFs works well: I can mount, open, read, write, rename, stat, and unlink data.But f_mkdir() fails every single time, unless I'm running in debug mode. It's exactly the same code with f_mkdir(). Th...
For STM32F746 Discovery. This seems to work with buffers from 1 to 20 or so. If you have comments I am happy hear them. Unfortunately for UART6, because that is easily available in Discovery board.I used UART_TwoBoards_ComIT example as a basis, so yo...
The f_mount() function initially returns FR_NOT_READY then on subsequent attempts to mount the SD card the f_mount() function returns FR_DISK_ERR.There seems to be a lot of posts with a similar (or same) problem on the STM32F4.I have followed severa...
Hello,I have following Problem. Iam try to get Data from the MEMS and send it via Ethernet to another Controller. My issue is, that the Pin PA7 is used for the SPI Mosi and the Carrier Sense Data Valid by the Ethernet (RMII). Now iam trying to recei...
I'm seeing a bug in STM32Cube_FW_F1_V1.6.0.I was using timer 2 in up counting mode with a prescale value of 6399, however the prescale value was not being used. After stepping through the code I noticed a bug in the LL_TIM functions.The LL_TIM_Disabl...
Hello all,I am using an STM32H7 and STM HAL drivers V1.2.0, SPI slave in interrupt mode.My requirements are as follows: Receive messages of unknown sizeReceive messages at any timeAbility to transmit at any timeSo far I am having the following issues...
I've been trying to run some examples with FreeRTOS and lwip stack but I can't make it work. I'm using CubeMx to generate the config just like this tutorial: https://www.carminenoviello.com/2016/01/22/getting-started-stm32-nucleo-f746zg/And working ...
So, does OTG_HS support HS host mode?Also, if FSLSS=1 and read only, shouldn't the reset value be 0x0004? In OTG_FS, it's 0x0200... (i.e. we again have here a bunch of undocumented bits). And FSLSS is *not* read only there, can be written to 0 or 1.J...
I am working with STM32429i-eval and try connect it to PC. I think that there are two mistakes at stm32f4xx_hal_uart.c. Into void HAL_UART_IRQHandler(UART_HandleTypeDef *huart)Instead of if(huart->ErrorCode != HAL_UART_ERROR_NONE)need if(huart->Err...
hello! as I want to implement TCP/IP and Fatfs based application I have to use HAL library which I'm not very comfortable with. so for other peripherals like USART, SPI and I2C i want to use STD peripheral library which is much easier to understand a...
