[参考译文] CC3351：校准器：校准器无法在 OTP 中读取和写入 MAC

尊敬的 Shi：

我已将其分配给一位硬件专家来提供支持。  

您好、Dylan、感谢您的支持、软件专家 更适合支持此问题。 您能帮我们指定一位 软件专家吗？  

您好、Shi、

请尝试对“get_efuse"命令“命令使用以下语法：

校准器 wlan0 cc33xx_plt get_efuse -mac_addr -wifi6_disable -rollback_protection_enable -country_code_restriction -country_code -vendor_key -vendor_key_usage

例如、如果要读取在电子保险丝中设置的 MAC 地址：

校准器 wlan0 plt POWER_MODE 开启

校准器 wlan0 cc33xx_plt get_efuse -mac_addr

只有在电子保险丝中已设置了某些内容时、get_efuse 命令才有效。 这意味着如果您没有在电子保险丝中设置 MAC 地址、get_efuse 命令将返回错误。 默认情况下、在电子保险丝中未设置 MAC 地址。

要设置电子保险丝、应使用以下语法：

此致、

Jonathan  

您好、Jonathan：

它 在 OTP 中包含 Mac、我使用“calibrator wlan0 cc33xx_plt get_efuse -mac_addr“。 这是测试日志。
