推荐答案

魔数 7F45 指定了可执行和可链接格式 (ELF) 文件类型，这是一种在 ARM 处理器上无法执行的格式.

Magic number 7F45 specifies the Executable and Linkable Format (ELF) file type, a format that is not executable on ARM processors.

原因可能是不正确的交叉编译或使用了错误的工具链.

Reason could be either improper cross compilation or either using wrong toolchain.

使用正确的工具链应该可以解决这个问题

Using correct toolchain should fix this problem
