もうじきARTIX-7でLinuxが起動しそうです
Artix-7でLinuxを動かそうとしています。
u-bootにロードするときのアドレスの指定でいろいろと勘違いしていたのと、FDTのアドレスの指定方法の知識が足りませんでした。
いろいろ試していたら、ついに、U-BootがLinuxのカーネルを読み始めて何か出てきました。

どうやら、Illegal opcode exception in kernel modeということから未定義命令か何かを踏んでしまっているようです。
あと少しな気がしてきました。

Without an elegant and outstanding dress or an outfit, a woman cannot look stylish and impressive. This brand will make you an eye candy of each and every informal occasion. Looking for fashion finds for less can be easy if you just look around more at less expensive stores. In Connecticut, bed bugs climbed the pole inside a firehouse; in Pennsylvania, an infestation occurred inside a classroom, and last year in Colorado bed bugs were found in a library. Indo Western wear for women is the best solution . Dial it down and you've got a pretty solid first offering from an album that could actually throw us a few surprises.
