Moved to the support forum.

You need to check 2 things:

1) Clock settings for PHY.
2) GPIO settings (alternate functions) in your board.h for MAC.

thank you for responding, which files do I need to check?
what is hal_mac?

Hi,

It is obvious that you are new to ChibiOS, which board are you using? is one of those supported or something else?

I use stm32f765, the program I use in this board from the example RT-STM32F769I-DISCOVERY, for blink and serial work but when MAC enabled board does not work

So you are not using a supported board.

You need to create board files for your board (board.h board.c) or it will not work, board files contain the settings for all GPIOs and external clocks. Creating board files is quite complex because all parameters have to be inferred from the board schematic and then chosen from GPIO tables on the data sheet.

I suggest to get a supported board to start gaining confidence, starting with a port is probably too complex.

on mac_lld_init I found the problem, on the mii_find_phy (& ETHD1) and while mii_read (& ETHD1, MII_BMCR) & BMCR_RESET), which made the bord stop working.
