Hi i'm trying tcp server with stm32f427 which combined LAN8720A phy chipI got a problem with this codeHAL_StatusTypeDef HAL_ETH_Init(ETH_HandleTypeDef *heth) { uint32_t tickstart; if (heth == NULL) { return HAL_ERROR; } if (heth->gSta...
I have my board running well, and flow control works in the "IN" direction (board -> PC).But there are strange issues. I am testing with a loopback program which has variable size packets and at a point which is very close to 1024 bytes I see a lot o...
Related to the STM32G030xx HAL driver.Many examples of the macro __HAL_FLASH_CLEAR_FLAG use multiple flag values ORed together. The comments on this macro seem to suggest that this is OK since the plural form is used on flagS ("Clear the FLASH pendin...
Use caseI'm planning to perform STM32 firmware update over I2C. For this I need to communicate with the STM32G030C6 system memory boot loader using some other host controller. In our system we'll be using the BOOT0 pin to decide the boot area at the ...

Specifically the SNB (SSN1 & SSN2 in the data sheet) bits are defined erroneously as being 3 bits wide at position 6, whereas it should be 7 bits wide, allowing all 128 sectors in each bank to be erased.#define FLASH_CR_SNB_Pos (6...
HiI want to use FreeRTOS with low power STOP2 mode without using the ticklessidle mode.One of the tasks once every cycle goes sets the mcu into stop2 mode.I’m using both RTC and LPUART for waking up the mcu.when using with just two FreeRTOS tasks all...
