如何搭建龙芯2k0300-久久派开发环境并升级内核？

在《龙芯2k0300 - 久久派开发环境搭建及内核升级（上）》我们对久久派开发板以及uboot、内核、文件系统的编译进行了介绍，本节主要介绍固件的升级，以及驱动移植。 一、更新固件 久久派开发板默认配套的是PMON固件以及linux 4.19的内核，这里我们打算将其替换换为uboot以及linux 6.12版本。 1.1 准备工作 1.1.1 串口连接 供电：久久派开发板集成了一个Type-C接口，用于给板子供电，板子上丝印标注DC-5V。 串口：龙邱久久派扩展板上也有一个Type-C接口，其连接久久派UART0，电脑通过Type-C数据线可直接控制久久派，使用更方便。 注意：实际上如果通过串口连接，供电接口可以不用了，因为久久派和龙邱久久派扩展板5V是连通的，所以任意一个Type-C接口提供5V电源都可以。 我们将扩展板上的串口连接到电脑，然后打开电脑的MobaXterm，选择串口端口（我这里是COM4），设置波特率115200。 1.1.2 测试 当我们按照前面的步骤接好线，给久久派复位上电，刚买的板子默认会输出如下信息： 点击查看详情 PMON2000 LOONGARCH Initializing.
