Hi All,I'm having a terrible (fun) time trying to get the DP83848 to work with the STM32H743 (RMII).No packets, no interrupts, nothing. - it's just dead to the world.I can get things working with the LAN7842 and I can get the DP83848 working with the...

Hi!when I run the HAL example code LwIP_HTTP_Server_Netconn_RTOS I get HAL_ETH_ErrorCallback() called on every packet, but the program seems to work fine.its this bit that gets called (so something hapenning with DMA)if((HAL_ETH_GetDMAError(heth) & E...

As far as I can tell, there is a bug in mem_init() in mem.c this can cause a memory overrun and hard fault (if you're lucky) In lwipopts.h I set LWIP_RAM_HEAP_POINTER = 0x30004000 MEM_SIZE 0x4000 I would expect the pool to be from 0x30004000 to 0x300...

Hello!I’m struggling to get a decent jpeg frame rate with both OV2640 and ov5640 using DCMI. I'm getting about 10fps!I’m using what seems to be the technique that other are using to determine when a jpeg frame has arrived. while (1) { jpegComplete...

All,I'm finding that concurrent DMA driven SPI transfers are failing.its STM32H743, Latest HAL, latest Cube and followed all rules with cache configuration etc etc.I’m running this in different FreeRTOS threaads and if I put a mutex around the HAL DM...

Thanks for the link.It all seems to be working now - It might have been down to bad wiring between the microcontroller board and breakout board, rather than the my code.I will incorporate the code you referenced into mine.Mark

Hi DK.Did you ever sort this out?I have exactly the same problem. I've tried the the LAN8720 and DP83848. with no luck.I've tried it on the WeAct STM32H743 and the WeAct STM32H723. I've spent several days on this so far - and I've tried absolutley ev...

The ethernetif.c code attached shows a MII interface not the RMII, which the Nucleo has. Its also showing the DP83848_PHY_ADDRESS, but the nucleo has a LAN8742. Try looking in the HAL example/CubeMX code for a better offering.(The HAL examples have s...

FYI - I had the same problem and the fix workssee my post (done before I found this one)STM32H723 HAL example raises HAL_ETH_ErrorCallback on every packet, but still works!click here to see it

Thanks for the quick response and fix.I had seen this error for a long while and never really looked into it as everyhing seemed to work ok.sad to see it go - was becoming a familiar friend :)
