LPC54608 MAC address

実奥山 — Mon, 08 Oct 2018 01:21:38 GMT

There are following MACADDRESS registers.

Table 721. MAC address high register (MAC_ADDR_HIGH, offset 0x0300)

Table 722. MAC address low register (MAC_ADDR_LOW, offset 0x0304)

Are these non-volatile?

If those are volatile,I have to preserve MAC address to flash.

Is below OK for preservation method to a flash?

const unsigned char * macaddr;

printf("0x12\n", macaddr[0]);

printf("0x34\n", macaddr[1]);

printf("0x56\n", macaddr[2]);

printf("0x78\n", macaddr[3]);

printf("0x9A\n", macaddr[4]);

printf("0xBC\n", macaddr[5]);

Hi 実奥山
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
After reviewing your question, I don't find you use the pointer macaddr points the MAC address, so you can use the below method to make it.
const char Test_str[6]= {0x02, 0x12, 0x13, 0x10, 0x15, 0x11};
Have a great day,

Thank you for your help.

Can I write Test_str(MAC address area) by my application program?

Please teach me how to write Tset_str.

I have to initialize MAC adress,IP address etc. by my application program.

Hi 実奥山,

Of course, you can define the MAC and IP addresses in the application.
For instance, you can use these below codes.

const char MAC_ADDR[6]= {0x02, 0x12, 0x13, 0x10, 0x15, 0x11};
const char IP_ADDR[4]= {192, 168, 0, 102};‍‍‍‍

Have a great day,
