[参考译文] AM69、无法从 uboot 引导 Linux FS

问题可能在这里

加载"/boot/dtb/ti/k3-am69-sk.dtb "失败
libfdt FDT_check_header ()：FDT_ERR_BADMAGIC
未配置 FDT 存储器地址。 请配置
通过"FDT addr "添加 FDT 地址

另一个提示是 uboot 不会发现 SD 卡  

=> MMC 列表
MMC@4f80000：0
MMC@4fb0000：1

此处是来自预构建映像的 env 配置，该映像由 TI 捆绑在 SD 卡中。 但与传统的略有不同、

尊敬的 Marcin：

您是否可以通过将 tiboot3-j784s4-hs-fs-evm.bin 重命名为 tiboot3.bin 来尝试将 tiboot3.bin 替换为 tiboot3-j784s4-hs-fs-evm.bin？

谢谢！

法比亚纳

我已经这么做了、正如我在这里提到的 FS、"我有 HS-FS 板、所以我将 tiboot3-j784s4-hs-fs-evm.bin 和 tiboot3.bin 放置在 SD 卡的引导分区中、它与 hs-fs bin 链接"、因此、基本上我采用了  tiboot3-j784s4-hs-fs-evm.bin 复制它并将副本重命名为 tiboot3.bin、 两个文件都放在 SD 卡上、就像在随电路板提供的 SD 卡上一样。 这意味着它在这里不是解决方案、  

如您所见 、K3-AM69-SK.DTB 位于2个分区上

尊敬的 Marcin：

您使用的是 SK-AM69还是 AM69 EVM？

谢谢！

SK-AM69、我使用的是 SDK  

TI-PROCESSOR-SDK-LINUX-EDGEAI-J784s4-EVM-09_01_00_06-Linux-x86

我已经决定重新构建内核以便能够访问 dtb 目录，它的问题消失了，但显示了新的
