CubeMX initialize MAC adress from external memory

[SiegiAtHome]

Hi,

what is the correct way to initialize the MAC address read from an external memory by using LwIP?

 /* Initialize all configured peripherals */

..

=> need MAC address here do correct initalization...

 MX_LWIP_Init();

...

=> MAC address can be read here from SPI flash or similar...

 MX_SPI2_Init();

 MX_SPI1_Init();

...

my suggest (but not possible within user code sections):

 /* Initialize all configured peripherals */

...

=> MAC address can be read here from SPI flash or similar...

 MX_SPI2_Init();

 MX_SPI1_Init();..

...

 /* USER CODE BEGIN READ MACADDRESS */

=> USER CODE SECTION could be useful here to read MAC address from external memory

 /* USER CODE END READ MACADDRESS */

...

 MX_LWIP_Init();

...

thanks

In my experience, manufacturers most often avoid the costs of external chips, and rather patch the MAC address (or other specific data) into the HEX file.

Thanks,

but however, I have to read out MAC Address from an external memory. If an firmware update has to be done, I can't patch all the HEX files individually.

Perhaps others have the same problem?
