PROCESSOR-SDK-AM64X: AM64X-EVM network module I2C read address

Part Number: PROCESSOR-SDK-AM64X
Other Parts Discussed in Thread: SYSCONFIG

Hello，

I am now running the network module routines. All routines (such as C:\ti\mcu_plus_sdk_am64x_09_01_00_41\examples\networking\lwip\enet_cpsw_socket) must change the I2C Address here to 0x68 before the program can run, otherwise an error will be reported.

Enabling clocks!
Assertion @ Line: 364 in syscfg/ti_board_config.c: ENET_GET_NUM_MAC_ADDR(numMacMax) <= ENET_BOARD_NUM_MACADDR_MAX : failed !!!

But according to my understanding, this place should be the address of EEPROM, then its address is 0X50, and 0x68 is the location of RTC, and all routines use 0x50. I run the routine here C:\ti\mcu_plus_sdk_am64x_09_01_00_41 \examples\drivers\i2c\i2c_read is normal for reading 0x50 data

1 Why can’t I use 0x50 in the network module?

2 Will it affect my program if I use 0x68?

Hi Gary Lu,

Sorry for delay in response.

What we understood from your question is that you have a custom board.

If you want to change EEPROM Address as per your configuration, you need not to change in code but in sysconfig

We do not have RTC on our EVM, so can you please provide more background what you are trying to achieve and how ?

Best Regards

Hello，

Now I just want to connect to the network. I have checked the official routine, which reads at 0X50. However, I need to change the reading location to 0X68, which is RTC. According to what you said, there is no RTC on our EVM. So, is it okay for me to change it to 0X68 to use it?

Regards，

Gary
