Hi everyone,I wonder if someone has successfully interfaced STM32 MCU with LAN9303 switch RMII mode using lwip library? Could you give me any clue?Thanks in advance.

Hi all,I'm currently working on a project using the STM32H723 interface with SDRAM IS42S16400J. After booting up, I have to read a large JSON file [2MB] from flash into SDRAM then parse it to get the information. I wonder if I could allocating dynami...

Hi everyone,I have a project using STM32H723ZG interface with SDRAM IS42S16400J (via FMC) and LAN8742. If I enable both FMC and LWIP to run with FreeRTOS, my program ends up jump to hard fault handler. If either FMC or LWIP is enabled with FreeRTOS, ...

What do you mean by "from external SDRAM"? Do you want to allocate lwip stack/pool memory from sdram?

Currently, I'm using H743, both SDRAM and LWIP work fine. :D

Thank you. After struggling with the linker file and _sbrk function, I'm able to move the heap section into sdram :)

Could you please share your linker file. Thank you.
