My board has ethernet PHY Micrel KSZ8721.I use STM32F407, RMII, LWIP, noRTOS.CubeMX 6.7, STM32Lib 1.27.1Although this is no exotic PHY, it is not listed in the supported BSP PHY as LAN8742 and DP83848.How can I write a mock driver so that custom call...

Hi,I have a chip marked as STM32F437 but my software fails on running the SHA256 algorithm on the hardware crypto module.The only difference to the STM32F427 is the additional presence of a hardware crypto accelerator in the STM32F437.How can I check...

Hello All,I have updated to CubeMX 6.5 and STM32F4 1.27 and now thinks are failing in my project.I could reproduce this using NucleoF429 board.When I create example from example selector LwIP_HTTP_Server_Netconn_RTOSit activates ethernetI can ping th...

I have a Nucleo-F429ZI and build a simple app using CubeMX pretending a F439ZI.When I access the HASH module there is no bus error or similar.It looks like reading all zeroes from this (nonexisting) HASH module.The default generated system ISR should...

Here is the description of the Chipmarkings as read from the device datasheet STM32f437.For me the 2 and the 3 in the second line, right position, are the revision codes.Maybe a synonym to line codes?Regard, Adib.--

Hello Tesla DeLorean, thanks for your response.2018 week 27 is fine. I have problems on the other year 1 week 33.This one reports revision "2". I checked our old PCBs. We have Revision "3" back to 2016.As the code is same on the boards I would expec...

Hi Peter, could you please check the chip marking for the bad chip.?it displays in the revision position a "2" where the good chip displays "3".In the errata sheet ES0206 there is no such revision "2" listed for STM32F427/437 ???Only revisions "A", "...
