8MHZ HSE crystal. HSE selected and PLLCLK selected.64MHZ / 115200 / 16 = 34.7222Assuming the CPU picked 34 as the divisor then the baud rate is 117647.1 2% too highBut setting to 59MHz I was able to successfully communicated at 921,60059MHZ / 921600 ...

2 months ago I started from link below, however I use it to write firmware to an onboard SPI Flash with an STM32F417 and stm32cubeide.https://community.st.com/s/question/0D53W00000LFUOmSAP/lwip-tftp-on-stm-boards

Can't share .ioc as it's a production version, but prepared to share the customized BSP_PlatformIsDetected() function.The issue is we have 2 generations of board, using 1 common code set, and 1 .ioc file and 1 bin fileThe difference between the boar...

regarding divisor if I understand you correctly please see response to @Community member Hope ST see suggestion for nomimal error.

from RM0454 Rev 3 Page771The oversampling method can be selected by programming the OVER8 bit in the USART_CR1 register either to 16 or 8 times the baud rate clock (see Figure 267 and Figure 268). Depending on your application: • select oversampling...

Answering my own questionLWIP 2.1.2 is in STM32Cube_FW_F4_V1.25.0 and STM32Cube_FW_F7_V1.16.0Thanks much appreciated

User Activity

fatfs_platform.c needs a section /* USER CODE BEGIN Includes / and / USER CODE END Includes */ so we can call our user defined functions in BSP_PlatformIsDetected(), otherwise when the code is regenerated the manually inserted includes are lost.

STM32G070: UART speed of 115200 is not possible with PC when running SYSCLK clock at 64MHZ - however is when run at 59.0MHZ

About to upgrade to STM32CubeIDE 1.4.0 and find that the release notes are still only for 1.3.1. When will they be released? When clicking 'check for updates' in the 1.3.1 IDE, the 1.4.0 update has no details either. Thanks Alec

Please advise when CUBE MX libraries will be updated to LWIP 2.1.2

Trouble creating a working HAL + FatFS + SDIO + DMA+ FreeRTOS solution.
