RTD299X方案修改屏参,本例以海尔LE48A5000主板为例

xtqtd520

实验主板:海尔LE48A5000   RTD2995+单EMMC    没试过其它本芯片主板,理论上只要是299X进入控制台,应该都可以修改连接好TTL小板(编程器也可)到主板的4pTTL端口,打开超级终端按住ESC不松,主板上电,出现提示符Realtek>  后松开,先前查看一下当前的屏参,在打印信息中查找,当前使用的屏参,参考下面的打印信息,注意看红色的我已经标注出来的.

我们随便选择一个屏型号来试一下
输入 panel -s Haier_Samsung_48_panel.bin  回车  (只需要复制相应的文件名,目录不用复制)
出现以下提示:
Panel: Use parameters in tmp/factory/bin_panel/panel/Haier_Samsung_48_panel.bin

修改完成,现在我们来重启一下再来看看
