Hello @Imen.D, We still have this issue on certain custom boards designed in-house. We use KSZ8095 on some and KSZ8895 (5 port) on others with same base circuit over MII/MDIO. We have tested the clock signals and they seemed to meet the STM32H7 sign...

Posted on January 08, 2014 at 03:33We just bought ST-Link to debug our software. Everything works great with Atollic and Seger J-Link with ST32F407 chip.But when we switch to ST-Link, we can flash the chip, but when start the debugger (in JTAG mode)...

Hello BR,My EE confirmed that the ethernet chip IS coming out of the reset. He also confirmed that he didn't find any use of D29 as well and removed it for the testing.Any thing else we can check?

Hello BR,We have followed the circuit as described in KSZ8895 and KSZ8081 phys.We use Nuttx and drivers provided by Nuttx to setup Ethernet. We have confirmed that the sequence of initializing Phy and MAC is exactly the same as HAL code generated by ...

Hello @NOza.2 Did you find a solution?For us we are using STM32H7 with KSZ8081 and feeding 25MHz clock to Phy which in turn is sending 25MHz clock to STM32H7 and using MCO1 to drive the MAC all using MII. We run into same problem with some boards, no...

Hello Benedict, We have the exact same problem, which PHY are you using? We have an external micrel PHY.
