嗨，我注意到Wandboard Quad中的USB有一些奇怪的行为，内核4.15 / Ubuntu 18.04 armhf（来自Ubuntu netboot安装的库存内核）。在系统启动时正确检测

本帖最后由 一只耳朵怪 于 2018-6-20 15:02 编辑 1.我們的板子想用使用ramdisk 來當rootfs ( TI Linux SDK 6.0 )ramdisk 放置於SD卡 boot分區2.我該如何修改uboot 讓kernel 開機可以自動載入ramdisk??(不使用setenv 方式)

刚买回来的华美A100路由器，马上想刷一下固件试一试摄像头功能，可为什么根据视频一样的方法就是刷不进去呢？ 步骤跟视频一样，但是最后是出现TTTTT字样不是....字样，就是刷不进去。

本帖最后由 一只耳朵怪 于 2018-6-21 11:43 编辑 自己做的3358板子，使用ddr3（和BBB一样），nand启动；使用sdk8.0的uboot和kernel，修改了uboot中的read_eeprom、sdram_init中config_ddr使用和BBB一样的参数。 在启动时，串口信息如下：U-Boot SPL 2014.07-00107-gd28f2b9-dirty (Jan 23 2017 - 16:27:26) The Expected Linux image was not found.
