Hi,

I find there is no applictation note about how to use IEEE1588 on stm32f107. As a newbie, it is very hard to start. When i enabled the timestamp function, and adjusted the ethernet receive processing, but the ethernet was dead. Who can tell me how to initialize the timestamp and the ethernet correctly?

Hello,

I have exactly the same problem with a STM32F207. When I enable the CPU timestamp, I have a strange behavior with Ethernet controller : the MAC register tells me that the DMA never start (

ETH_DMABMR->SR is never set to 0).

Thank you in advance for your help. Best regards, Thomas
