R3300L按reset键无法进入USB Burning模式的问题分析

由 与世无争的帅哥 提交于 2019-12-09 00:11:29
最开始并没有注意到这个问题, 因为从设备拿到手, 用USB Burning Tool刷入潜龙版的安卓4.4.2, 再到运行EmuELEC, Armbian, 再到给Kernel 5.3的Armbian编译RTL8189FTV的驱动, 都还算顺利. 因为Kernel 5.3也差不多搞定了, 开始打安卓的主意, 想看看能不能跑7.x版本的安卓. 固件包下了几个, 要开始刷的时候出了状况, 发现按着reset键再也无法进入USB Burning Mode了. 几经调查, 试了另外两台一样已经刷过的R3300L, 百度上查类似的案例, 发现其他人也存在这种情况. 而且网友们提供的处理方法(4R19接地)完全无效. 于是开始研究UBOOT 这个设备跑过的系统不外乎潜龙的安卓4.4.2, 以及各种版本的EmuELEC, 各种版本的Armbian, 通过查资料, 发现Linux下面的fw_printenv和fw_setenv命令可以查看及修改UBOOT下的配置. EmuELEC下可以直接运行, 但是在高版本的Armbian下, 仅有可执行文件, 缺/etc/fw_env.config, 于是又查资料找到了对应S905L的config. 通过分析UBOOT的配置, 可以确认EmuELEC和Armbian都会对UBOOT配置进行修改, 但是它们的修改只是在bootcmd里加东西,

Connection resets with simple Perl script

由 荒凉一梦 提交于 2019-12-08 13:46:16
问题 Below is a Perl script whose sole purpose is to receive an HTTP request, and spit out "503 Service Unavailable" and a short message. It works fine, except in many cases, the connection resets, which causes the browser to show an error message. This is on Win32. I have no idea what's wrong with it. #!/usr/local/bin/perl use strict; use IO::Socket::INET; my $f = join('', <DATA>); $SIG{CHLD} = 'IGNORE'; my $sock = IO::Socket::INET->new(ReuseAddr => 1, Listen => 512, LocalPort => 80, LocalHost =>

JQuery: Fading Out, Performing an Action, then Fading Back In

由 扶醉桌前 提交于 2019-12-08 06:03:55
问题 So I have what amounts to an html form, but is not an actual <form> , per se. I have a 'Clear' button that I am currently using to reset all of the fields back to their defaults. From an aesthetic standpoint, I would like for the form to fade out, reset while it's "gone", and fade back in completely reset. I've got this code so far to try to achieve this: function Reset() { $formDiv.fadeOut(function() { // perform reset actions here $(this).fadeIn() }); } However, what happens is, as the div

Git: temporarily reverting pushed commit(s)

由 天涯浪子 提交于 2019-12-08 05:06:23
问题 Say, you've pushed some commits and pulled them into production, in your server's webroot, for example. And then something goes wrong. Clearly, most often what you want to do is temporarily revert the files in the webroot to some previous state, then go back to your local development place, fix what is broken, test it, commit on top of commits that broke something and push these new fixing commits to the master branch. And then just go to the production webroot again and pull everything to

How to create Reset button in iPhone Settings

由 空扰寡人 提交于 2019-12-08 03:54:47
问题 How can I create a "button" in Settings bundle? Something like "Import SIM Contacts" inside Mail settings? Or "Reset Calibration" in Nike + iPod application? Need to have a " Reset Username and Password " button for Settings, if that is a special case... I mean how can I add logic to clear some of other settings, while my own app is not running? 回答1: You can't run custom code in settings, so this is commonly solved with an on/off switch to reset settings at next launch. When the app launches,

Automatically set mysql autoincrement to min value

由 混江龙づ霸主 提交于 2019-12-08 03:20:29

Reset Spring-Boot During Integration Tests

由 混江龙づ霸主 提交于 2019-12-07 20:22:34
问题 I guess am trying to get a corner case to work here. In my current project there are about 20 integration tests. One new integration test requires @EnableAsync to make the test work: @RunWith(SpringRunner.class) @EnableAsync @SpringBootTest(webEnvironment = WebEnvironment.NONE) public class MyITest { : } When run alone, this test works fine. Considering Maven and Eclipse' execution of tests in one project and knowing that the environment is only created once and reused (or soft-reset) for all
