<br></blockquote><div><br></div><div>Hi Steve,</div><div><br></div><div><div>There is a patch in the chromium flashrom tree that add support for firmware 6.0+ (which may or may not include 6.5.3) that does not seem to be in the upstream flashrom:<br></div><div><a href="https://chromium.googlesource.com/chromiumos/third_party/flashrom/+/543101a06832b4e3a0d89ec9bf81ec398ff5808e" target="_blank">https://chromium.googlesource.com/chromiumos/third_party/flashrom/+/543101a06832b4e3a0d89ec9bf81ec398ff5808e</a><br></div><div><br></div><div>I suspect the chromium flashrom tree has diverged enough from upstream that it will not apply cleanly there but it is only a 130 line patch so it shouldn't be too bad to integrate if needed.</div><span><font color="#888888"><div><br></div><div>-duncan</div><div><br></div><div></div></font></span></div></div></div></div></div>
