@cgzxilinx 在 t113主频问题 中说：

t113可以长期工作在1.2G主频吗，我看很多厂家只跑800m的

同问，是否降低到800M就能到工业级温度范围

@awwwwa 多谢指导，已经解决，整个clean以后重编就生效了，搞不懂之前咋回事，好在最后解决了

串口0-5都开启了，其他串口都正常，唯独串口2找不到设备，dmesg看到PD1被lcd0占用
[ 0.736249] sun8iw20-pinctrl 2000000.pinctrl: pin PD1 already requested by 5461000.lcd0; cannot claim for 2500800.uart
[ 0.756395] sun8iw20-pinctrl 2000000.pinctrl: could not request pin 97 (PD1) from group PD1 on device 2000000.pinctrl

[ 2.617710] sun8iw20-pinctrl 2000000.pinctrl: could not request pin 97 (PD1) from group PD1 on device 2000000.pinctrl
在board.dts里面把&lcd0和&disp里面都添加了status = "disabled";并且把相关引脚引用都注释了，还是报错PD1被lcd0占用。
//pinctrl-0 = <&dsi4lane_pins_a>;
//pinctrl-1 = <&dsi4lane_pins_b>;
继续改，把uboot-board.dts里面的lcd0也给disabled还是报错PD1被lcd0占用，求教哪位老铁遇到过？指点一点线索，多谢多谢

@wyljkl 请教t113的tina2.1 sdk哪里可以下？

T113能在新平台下么？

@whycanservice 有支持linux计划么？看着高配的有32m内存，可以替代f1c100

@chhjnavy 感谢谢谢帖子，对于入门非常有用，万丈高楼平地起

@lingeasy 没解决，放弃吧，我花了一周多时间全浪费了，我得结论是wifi的sdio只能接到参考设计的那个口，我最后重新改了板子解决的，把口换回去

@mysteryli dvp针对低像素场合，不超过200w像素，便宜的不行

这种30w的dvp超便宜，五块钱以内，甚至200w的dvp 2640也就十块钱，适合大量走货，问下sdk有没有已经适配过的型号？

@super0759 老铁，开源版本目前只有853的支持，你看到的楼上截图是商业用户的界面

@georgelzh d1s

@lovexulu 多谢老铁

@lovexulu 怎么解决的？我之前还发了个帖子说tf启动到kernel就没下文了

@whycan 只留了一个tf卡，大概率跑不起来，我蹭了2颗851，发现sdk的tf启动引导有问题

@ftwtwzy fe8.1的hub芯片有驱动么？

0603安逸，不用眼瞎去焊接了，这个好歹弄个wifi上去啊！851的sdk也没释放呢

@yuzukitsuru 全能靓仔

@yuzukitsuru 能跑到多少带宽？

直接拿官方放出来的镜像最省事

@l13819506056 RTL8152的usb驱动是sdk自带了么？

@mangogeek 芒果大佬，如果要改sdc0连接wifi，除了改dts还需要改其他文件么？

@yuzukitsuru 麻烦再问一下除了dts需要修改，还需要修改其他文件么？

@yuzukitsuru 多谢指导，除了这个dts还需要改动哪些部分？

这里是哪没有配置好，新手入门，贻笑大方了

如题，默认是用sdc1，因为项目需要，sdc1被占用了做网口，板子实际是用sdc0作为wifi的sdio总线，wifi模块是8189ftv，改了board.dts，加载ko文件，没有扫卡动作。请教修改wifi的sdio号，需要做哪些操作？改动哪些文件？

@whycan 晕哥，853s的样品啥时候开卖？851s我看已经有样品卖了

@lyscut 可以买V851S先画板子，sdk后面肯定也会开放

能否放一个851用tf启动的固件测试下，从朋友那讹来了2片851，启动kernel，然后没有然后了，想找个能启动的固件测试下

@ubuntu14_0824 楼主写的很详细啊，写单片机的老铁们刚接触soc，都有这个适应过程，感谢分享

@lansecd 在 V853s芯片量产情况咨询 中说：

这是853不是853S

@yuzukitsuru 感谢指导，这一块有没有文档说明？怎么关rv小核没搜到资料。

@zhayujie 兄弟，这种环境的问题还是放弃折腾吧，老老实实用虚拟机。我已经搭进去一周时间折腾了，因为我用的是ubuntu22.04真机，不想在win下面开发，所以先后试过docker 18.04 docker 16.04 ，确实也解决了一些问题，但是没法解决全部的问题，最接近的一次是编译都过了，打包又异常。后来没办法在win下面装了虚拟机，放弃了折腾，太耽误时间了

测试阶段总是tf卡最方便，按照文档“Tina Linux 存储介质切换”修改了tf卡启动，改了fex文件的存储类型，修改了board.dts，硬件是sdc0接tf卡。编译和打包都没问题，但是启动报错，贴一下log，寻求指点，多谢~

v853s开发板

@xiaowenge 啥眼神啊你，那么大个核心板

肯定是V853或者853S了。那些猜113的咋想的？T113都有开发板了，没必要做二遍了

买了个480-272的电阻屏，按照帖子修补了驱动的补丁，现在可以正常显示了，但是触摸没反应，看了下dts，触摸ad已经是ok的了，还需要修改哪些地方？有做过的老铁提点一下

@yteraa 20.04没问题，我编过

淘宝299的有货能买到就行，申请僧多粥少，多上架几个是正经

@yuzukitsuru 新电脑硬件比较新，只有22.04支持好一点，但是编译这些老古董sdk就遭罪了

@yteraa 敢不敢给我上个ubuntu22.04么？

@soso90 模拟的就算了，跟幻灯片一样，还拉窗帘

原厂也不知道为啥么？我用d1s也出现过这个问题，j1效率太低了

@a-i-unicorn 淘宝买

我关心有没有教程资料？像6ull那种指导教程

这个板子有配套教程资料不？只有6ull一半详细就行

之前想把demo剥离出来的，能力受限没能实现，现在捡现成的，真香

用串口登录就没这个问题，sdk的问题，只能ls加参数

打样了一个多月啊

@yuzukitsuru 你简直是万金油，啥都知道

最近看到sd nand这玩意有意思，想折腾一下试试。但是贴到板子上面去以后，再次更新固件，要怎么样不拆下芯片就能烧录进去呢？折腾过的老铁们路过，指点一下

这个不错，感谢分享，终于看到了参考电路

核心板的原理图现在方便放一份么？

@bayche 挤牙膏也要挤多点啊，就这么针眼大一点，沾点水就化没了

整点干脆的嘛！一起放出来sdk得了

同问，啥时候开卖？需要你们家的教程

@frank_yuan ssh不就是么

d1s那个板子啥时候开卖啊？

板子开卖了么？这个拿来做学习不错

同问，有没有 d1s接网口的参考

放弃挣扎吧，我也遇到过，有时候用make j1又可以过。有时候咋都不行，整个工程删除重来，我遇到好几次了，ubuntu20.04环境

sdk啥时候开放啊

sdk已经开发了么？

@tripod9 能否讲一下电阻屏的驱动适配过程？

@luojia65 虽然看不懂，但不妨碍我表示感谢

@exoy28 20.04，14.04都没源了，我没有用虚拟机，装的真系统。昨晚发现make -j1没问题，make -j8就完蛋，搞不懂

D1S的电阻触摸现在还没有帖子说解决了，我今天试了menuconfig里面选上tslib都会编译失败，先驱们知道咋回事么

@mangogeek 底板底板

牙膏厂开工咯三天挤一点

可以安排上架销售了

@yuzukitsuru 老板威武，比原厂速度快

@anruliu 解释的太细致了，多谢热心指导

@yuzukitsuru 实在是不好意思，水平很菜，起步学习中，能多说一下具体是要改哪个文件夹下面的makfile么？我下载了论坛的lvgl7，解压后的目录里面直接有makefile，修改一下cc的工具路径就能编译了，但是tina2.0的sdk里面带的lvgl8工程结构不一样，菜鸟搞不清是怎么调整修改

2.0里面的lvgl8怎么能拿出来单独编译？不会cmake的白痴难在这一步了

比d1h那个板子好看一些了

@yuzukitsuru 你也太高产了，悄无声息又出新板子了

@yuzukitsuru 请教下小正太，如果想单独编译package/gui/lvgl需要怎么操作？比如说我把lvgl文件夹单独拷出来，独立于sdk之外，应该怎么编译？需要修改那些配置文件？

别一点一点上啊，一把梭哈全放出来过瘾

@a937983423 那是必然的，这不是现在还买不到么

等着放原理图准备抄作业

d1s如果真的cpu不够用，换t113也没好到哪去，不过内存翻了一倍还是舒服

@mangogeek 来来来，干完这一杯，还有三杯，继续画底板

@yuzukitsuru 来个完整的看看

@xiaowenge 小文哥，sdk啥时候释放啊，新妓到来，饥渴难耐啊

我感觉你这块会比芒果的出来的更快，船小好掉头

@yuzukitsuru 强顶，调通了我也想买一块玩下，跟一跟AI的潮流，不然落伍太多了

来个xr872整个活

一般两个脚幅度不一样，一边小一点峰峰值可能600mv，另外一边大一点，可能超过1.2v

@mangogeek 老板，核心板有哪些接口？看样子有一个wifi

已经五月口，说好的四月底发布呢？快快快，最近半年新ic太多了，百花齐放

全乎了这接口，为啥要用2路网口？

提个建议，既然板子空间有多余的，基本的复位和fex按键，40p rgb，摄像头，mic，喇叭pa， wifi这些还是尽量放上去，不用底板也可以是一个完整开发板

几时上市？买一个玩下

楼主威武，这都搞定了
