PROCESSOR-SDK-AM64X: AM64X-EVM enet例程运行失败

nub

我这边运行mcu_plus_sdk_am64x_09_01_00_41\examples\networking里面的所有例程都是在EEPROM_read(gEepromHandle[CONFIG_EEPROM0], I2C_EEPROM_MAC_DATA_OFFSET, macAddrBuf, (macAddrCnt * ENET_MAC_ADDR_LEN))这个地方失败，想问下是不是我要运行这些例程之前还有别的工作要做？网线我是接上的

请问用的是什么板子？对板子EEPROM有操作吗？

AM6442EVM,我对CPU和DDR初始化了，不知道是不是您说的EEPROM操作，有EEPROM操作教程吗？我试下

单独运行一下https://software-dl.ti.com/mcu-plus-sdk/esd/AM64X/latest/exports/docs/api_guide_am64x/EXAMPLES_DRIVERS_I2C_READ.html例程，看是否能读取EEPROM里的内容？
