And what more test should we do except to build images such as core-image-sato, core-image-sato even build world? 2 There 2 aarch64 configure files from linaro. First one is little endian and it is as default, and the other one is big endian. I take the little endian one as qemuarm64.conf as linaro does. Do we need add the other one as qemuarm64_be.conf or something like that? -- Regards, Neil | Kai Kang --------------030105090806020804050208 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: 8bit Hi Saul,
