T527有tina linux吧？ 这片子还是全志老朋友有点热情，3566 3568太火了

请问T527有Tina Linux吗？

贴主，做板验证了吗？ 查了下T113-s3的SDC2的引脚PC2~PC7内部是参考VCC-IO的，一般是接了3.3V，eMMC的VCCQ接1.8V会起效？

@xu13537826780 一般都好点，除非特殊的切割屏时序不好搞。您联系方式是？？

大佬，能贴下你的配置跟应用程序不，我这跟其他贴子的一样都是32个灯限制

买买买，上架了吗？

大家好，LEDC FIFO是32个深度，如果超出32个灯，像100个这样，怎么编程呢？现在产品上要用它来做，效果比3个PWM或者IO来好用多了，就是32个灯的突破要怎么编程还不知道怎么搞

LEDC在一个机型上要真正用起来，的确是个比较吸引视觉的部件，但32还是少了点

不错，买了根灯条回来，效果是挺漂亮的。不过FIFO最大32的深度，如果更多颗灯要怎么编程呢？

我也在设计，双天线有MIMO功能？？？ 还是只能选择一个？

对的，改default_lcd就行了，我贴几个验证过的lvds屏你参考下

GT911 接45P普通平板电容触摸屏的小板，大量便宜外屏可用了，一般45P的都是14x26的，如台电P20HD的。我这有3种类似外屏都是一样的45P.参数都能用一个。
网盘先上，里面有打版gerber和原理图， asc是可导入pads成PCB，也可用AD导入成PCB。

@xiaowenge 小哥稍等，我今天肯定上传到淘宝上，哦核心板，其它底板外壳的文件放百度网盘好了，

R528跟T113差不多，基本参考它就行。
LVDS好搞，如果参数不行，把分辨率改了后，直接用以前OK的时序先顶上调调看。

更新下动态，类似板型已经在产了，这个板基本引出了所有功能并经过了验证。准备上架核心板。

做了7.4" 1280x400和 10.1" 1280x800两种竖屏，使用G2D旋转后Framebuffer就是横屏操作，这点真的很棒。
外壳原型打印回来，喷上漆挺好看的，5个按键通过硅胶帽接触按压，很柔软舒服。

下面是10.1的，使用了G+G的普通平板外屏，做了GT911的电容屏小板，用产测工具固化好参数，就能使用便宜量大的平板G+G了。
10.1的竖屏真便宜现在， G+G也只要18，

哑光磨砂是挺有质感，以前见过一些老外的板子这种外观
坐等上架

@xiaowenge 暂时没用上它， 先预研下， 现在在用7.36" 1280x400和8" 1600x480的，这2货是LVDS横屏，但市场不多了。
刚好G2D有旋转功能，可以直接当横屏用了。 用过S3点6.86那时候还是得CPU去做旋转，有动态效果时CPU都到90%了。

画PCB， 画外壳，PCB上的接口有以下：
千兆RJ45 无POE
USBx2
TF Card
2.4G/5G Wifi， IPX/SMA接口的两种天线插座选装一种
5xKey (LRADC)， 5个按键在侧边，要装外壳有硅胶按键帽配合，非常舒服
2xGPADC， 4P XH2.54 单排针, 1.8V电压范围， PIN1准备了个1/2的分压来测试下。
2xMIC 1.25MM 2P插座， 配带线的MIC。
2x3W喇叭，贴板安装
3x全彩LED WS2812B ， 第3个LED的DO输出到 GPIO插座，可以再串接5V的WS2812B灯条。 据说1024个最大，但FIFO只有32个， 具体要突破这个32的编程还没Demo。
电阻触摸 4P 1.0mm插座
电容触摸 6P 插座
30P MIPI液晶插座
40P MIPI液晶插座 (此口配了个转10.1" 800x1280 液晶的转接板)
再GPIO简牛插座，PB2~PB12, PC0~PC1, PG8~PG11, PG16(LEDC应用，已经串接了 3个WS2812B)
CR2032 RTC电池插座，使用R528自身RTC， 精工晶振+村田电容， 精度室温10.x ppm左右。就是5V停电时电流有点大11uA了。一般够用。
Debug 3.3V TTL UART0 3P XH2.54插座, (PB0,PB1)
Type-C 5V电源插座

g2d_rotate_degree = 90是绿屏， 音频有，视频就是绿屏。
如果是1 是不旋转，这时正常。 是不是G2D旋转出了问题？

结贴，把LINE OUT关闭，只让HP输出即可。

在sound的soc-core.c中pmdown_time也更改过，从5000改到0x7fff ffff，也没用。

补充下，PA EN信号是正确的，我的MUTE信号是高电平静音，所以pa_level要设置成0x00.

R528-s3外接喇叭， 从HPOUTL HPOUTR引出信号到PA，使用PG17做为MUTE信号。 用aplay播放wav提示音时，会先有咔嗒声， msleep_time也调整过，都还是有，这个要从哪里着手解决呢？这个已经导产，是一个影响产品体验的bug.

pa_level	= <0x00>;
pa_pwr_level	= <0x01>;
pa_msleep_time	= <500>;	//0x78
gpio-spk	= <&pio PG 17 GPIO_ACTIVE_LOW>;

7.84最常见的量最大的应该是维泰的，但型号和生产日期太多了。于是点起来了，这不重要，
重要的是手上有3个规格，如WTL078401G05-24M, WTL078401G04-24M， WTL078401G01-18M
每个都有不同的生产日期，拿WTL078401G05-24M来说，我手上就有2017，2018， 2022，

开始是LT6911C点的， 除了04-24M外都正常。

放到R528上，只有05-24M的2017， 2018正常， 用逻辑分析仪抓包看，在初始化时最开始果然多了一个0x05写，这有坛友知道怎么来的么？
之前10.1 800x1280竖屏和1920x1200横屏挺正常，就没抓包看。

这个是多次抓包都会有这个0x05写命令在，所以可以排除逻辑分析仪测量错误，不过上百个初始化数据里面可能会有2，3个抓错的，多次抓对比一下就行。

好吧，功能基本调完，千兆的在genphy_read_status里面判断下phy状态，改下link speed就行了，千百兆都可以了。结贴。、
操蛋的是用的 南方硅谷的双频wifi竞然芯片停产了，特定搞了点库存，导产都不够。

之前调T113-S3也是如至的表现，这问题难道是我这独有么？

补充一下，插千兆网线时是千兆link灯亮， 插百兆网线时百兆link灯会亮，这样看芯片自动协商是正确的。

R528-S3接的RTL8211F，千兆网线正常， 接百兆网线还是显示千兆，而且无法udhcpc，这个要改gmac.c 吗？

好，2个CPU都起来了，OPTEE有需要时再看，暂时用不上。

@whycanservice 感谢，我试试，刚好功能全测完，只剩下这个问题。
是OPTEE打包后直接挂，所以去掉了OPTEE，结果又遇到SMP问题。

@barrng 不少啊，10.3寸，12.3寸的一些屏有单1920x720的。最新的16寸之类的条屏也是数据率上去了好多。

R528-S3上手，直接买芯片做的板，内核中配置PSCI会导致内核挂掉，报错__invoke_psci_fn_smc，而T113不会报这个错。

去掉PSCI选项呢，跑起来又只看到单核， 3个板都如此，难道买到次品芯片了？

各位大神有遇到这啥情况不？

现在16.2寸的双LVDS屏也都是单路LVDS上了100MHz时钟了

我观文档写是1366x768， 有个单路的1920x720的屏要点， 如果输出不了就只能加MIPI转LVDS芯片了， 或者寻找双LVDS转单LVDS的方案转一下

向群友请教个问题，T113的LVDS单路能输出1920x720 @60Hz的时序吗？ 一些HDMI转LVDS， MIPI转LVDS的芯片单LVDS输出的分辨率可以达到1920x720。
