器件型号：AM623

工具与软件：

您好！

我们在项目中使用 AM623定制电路板、但我们的电路板设计不包含 EEPROM 组件。尽管如此、我们在引导过程或操作期间会观察到与 EEPROM 相关的日志消息。这些日志在我们的设置中是不必要的、会在调试过程中引起混淆。

您能否指导我们如何从系统日志中抑制或删除这些与 EEPROM 相关的消息？如果需要更改配置、修改内核或更新设备树、请提供详细说明。

尊敬的 Vikash：

如果启用了配置选项 TI_I2C_Board_detect、U-boot 代码会显示 EEPROM 的状态。

#if CONFIG_IS_ENABLED(TI_I2C_BOARD_DETECT)
int do_board_detect(void)
{
	int ret;

	ret = ti_i2c_eeprom_am6_get_base(CONFIG_EEPROM_BUS_ADDRESS,
					 CONFIG_EEPROM_CHIP_ADDRESS);
	if (ret) {
		printf("EEPROM not available at 0x%02x, trying to read at 0x%02x\n",
		       CONFIG_EEPROM_CHIP_ADDRESS, CONFIG_EEPROM_CHIP_ADDRESS + 1);
		ret = ti_i2c_eeprom_am6_get_base(CONFIG_EEPROM_BUS_ADDRESS,
						 CONFIG_EEPROM_CHIP_ADDRESS + 1);
		if (ret)
			pr_err("Reading on-board EEPROM at 0x%02x failed %d\n",
			       CONFIG_EEPROM_CHIP_ADDRESS + 1, ret);
	}

	return ret;
}

请检查此配置的使用位置、并将其删除。

Re -构建 U-boot 源代码、然后重试。

此致、
