Other Parts Discussed in Thread: AM3359
在二手市场上，有很多拆机的蚂蚁矿机阉割版BeagleBone Black。硬件方面，将AM3359降级为AM3352，512M DDR3减少为256M。移除了eMMC并且加入了256M的镁光NAND Flash。
我按照别人的patch，轻松解决了U-boot的问题，就是选择am335x-evm_defconfig，然后给board/ti/am335x/board.c打如下patch，使其不从eeprom中读取型号，而是写死。
固件方面，我下载了这个AM335x 11.7 2023-09-02 4GB eMMC IoT Flasher - BeagleBoard
用xzcat am335x-eMMC-flasher-debian-11.7-iot-armhf-2023-09-02-4gb.img.xz | sudo dd of=/dev/sdx status=progress指令写入插在读卡器上的SD卡
之后用Gparted将rootfs分区右移使其空出128M。
之后再用fdisk在前100M创建一个启动分区放置uboot和内核就像BeagleBone Black 从零开始制作操作系统 - 知乎 (zhihu.com)一样
把rootfs里的/boot里的文件全部复制到启动分区，创建extlinux目录，在目录里添加extlinux.conf，内容如下：
随后接上串口，给板子供电
结果就得到了内核报错Unhandled fault: external abort on non-linefetch (0x1008) at 0xd2326000
dtb换为am335x-bone.dtb am335x-evm.dtb后，故障依旧，所以排除是内存大小设置问题。
我就拉取https://github.com/beagleboard/linux.git的代码，checkout到v5.10.168-ti-r71分支，按照教程加入hello_world.dts，make dtbs。
最后把hello_world.dtb复制到板子上，修改extlinux.conf。
最后离谱的事情发生了：报错居然还是一模一样！
最后贴出开发板打印信息：
