@maplerian 是的没错，感谢提醒

@caoniu 应用不需要修改，gpio相关控制由控制器实现，上层不需要关系

@maplerian

CS翻转问题请检查下逻辑分析仪的触发电平是否设置的太低？ CLK不匹配问题，请看下CCU中SPI相关的寄存器与软件设置的值是否有差异？或者用hal_ccmu打印当前时钟源信息看看SPI是哪个时钟源，频率是多少？

@kanken6174 不建议修改引脚驱动能力，因为i2c协议要求总线为弱上拉，提高IO驱动能力会使之变成强上拉

当VCC为1.8V时，上拉电阻应选用2K
当VCC为3.3V时，上拉电阻应选用4.7K

若无法正常使用，应排查走线质量与信号干扰。

使用spidev-test测试命令的-s参数可以调整spi速率

Usage: ./spidev_test [-DsbdlHOLC3vpNR24SI] -D --device device to use (default /dev/spidev1.1) -s --speed max speed (Hz) -d --delay delay (usec) -b --bpw bits per word -i --input input data from a file (e.g. "test.bin") -o --output output data to a file (e.g. "results.bin") -l --loop loopback -H --cpha clock phase -O --cpol clock polarity -L --lsb least significant bit first -C --cs-high chip select active high -3 --3wire SI/SO signals shared -v --verbose Verbose (show tx buffer) -p Send data (e.g. "1234\xde\xad") -N --no-cs no chip select -R --ready slave pulls low to pause -2 --dual dual transfer -4 --quad quad transfer -8 --octal octal transfer -S --size transfer size -I --iter iterations

@liuqiang UART转RS485 IC的流控通过IO脚进行方向控制，控制器本身并没有这种功能，需要在代码里添加相关GPIO操作

@miller370321 不需要，V853 vision直接把helloworld 文件夹加在package 目录下，然后，source build/envsetup.sh lunch 16, make menuconfig 就可以看到hello world 了

知道了，cd到对应的目录下，mm就好了

@rainnnn 我也是这个问题没法用呀

后来发现 我插入鼠标有反应，说明系统已经起来了，控制台却无法使用，boot和内核都能打印，应该不是这两个地方的问题，猜测是文件系统配置的问题，进入SDK /tina-d1-h/target/allwinner/d1s-nezha_nor/base-files/etc下的inittab 文件:ttyS0::askfirst:/bin/ash --login 控制台串口并没有改过来，改为ttyS3就能进入系统了。

是不是晶振附近有干扰 或者是买到了假的晶振

要使用G2G 加速和G2D 旋转 要先开双缓

@jr_online 你好，有修改成功吗，按照上面修改会报错 ：

@apollo_0101 直接找defconfig配置也行

@leomini5 谢谢 OK了

@huerli 大佬解决了吗 我也遇到这个问题

@whycanservice 明白了👍

@daizebin R128-FreeRTOS_v0.9.tar.gz

@awwwwa 大佬，我执行 mboot 的时候显示 boot0 和 uboot 都编译成功的，那是要怎么操作呢？

@zifeiyu https://bbs.aw-ol.com/topic/1701/tina-linux-存储介质切换-emmc-spi-nand-spi-nor-sd-card-sd-nand/2?_=1701672096020&lang=zh-CN

@awwwwa 好的谢谢

@lyg116 EMMC大概率支持，但是也有小部分是需要适配的

@pointzero36 这个错误应该是 ISP 信息获取失败了

@lw409309740 推测是 yolo 模型训练开发

@liker292 在服务器里面执行 make -v看看

@chrisvista 已经看到了是5.4.61

@damiaa 照样打补丁，打百问网的就行

@lyg116 自带fbviewer的

@lyg116 微信he1157173310

@kanken6174 谢谢，哪里可以找到让v851se工作的方法？理论上，除了ephy部分，v851s应该和v851se是一样的。

用的哪个版本的u-boot？

来个教程啊来个教程啊

@dsp2000 通过 Zadig 工具 把 "USB Device(VID_1f3a_PID_efe8)" 编辑名称为 "Allwinner SoC in FEL mode" 就行了。

@frank 这改完 lcd0 不能用了啊

把t113换成d1s，能启动了、

@whycan 在 D1s 如何使用TVIN1作为输入源？ 中说：

@meihao
不是 0x10吗？

在这里也能看到晕哥
感谢晕哥对各位小伙伴的支持
我还需要水一个帖子，升级到LV2拉取SDK

但是到目前为止，我还没确定选D1S还是T113 S3?

新版ubuntu就这样。
报错已经说明了
要安装python2就使用

sudo apt-get install python2

要安装python3就使用

sudo apt-get install pyhton3

要使用python这个执行名称，就安装python-is-python3，即将python链接到python3.

@daizebin 那要怎么解决这个问题呢

@awwwwa 谢谢回复。所以XR829的LPCLK是可以接地的吧？ 知道内部RC不准确，只要不影响WIFI工作就好。

想要使用wifi adb 应该做什么？

列表目前我的板安装这个操作可以正常使用adb

@dream 同步最新的信息， 已经使用了 mutex 的方式，替换文件锁，可以解决 opkg remove 和 opkg list 等指令不能正常使用的问题，目前 opkg install 会出现段错误。

原以为解决了文件锁，就能解决 opkg 不能使用的问题，没想到只解决了一半🙄

@fanhuacloud 谢谢大佬

@awwwwa 这儿改了也没用。
我都测过了，即使一起改了sys_config.fex和uboot-board.dts里面的，仍然不起作用。

我这个应该时韦老师的sdk搞得鬼，他给spl的clock.c里面强制写了个1008M，不受配置文件的控制了。

@awwwwa. 这个又随机出现了一次，这次好了，刚启动就卡了

@awwwwa 好的谢谢

@awwwwa 了解了, 非常感谢

测试使用串口 ttyS1 正常，关闭 CONFIG_SERIAL_8250

@ethan_00 可以通过U盘来写入设备树dtb overlays覆盖原屏参

Makefile:68: *** missing separator. Stop.

这个错误通常表示在 Makefile 的第 68 行或附近存在语法错误。Makefile 中使用的规则必须遵循严格的缩进规范，通常是使用 Tab 键进行缩进，而不是空格。

请检查 Makefile 第 68 行附近的代码，确保每个规则的命令部分都以 Tab 键开头，并且规则名称和命令之间使用冒号（:）分隔。此外，还需要确认 Makefile 的每一行都是使用相同的缩进方式，要么都是 Tab，要么都是空格，不要混用。

默认HDMI不开，需要命令开启

cd /sys/kernel/debug/dispdbg echo disp0 > name; echo switch1 > command; echo 4 10 0 0 0x4 0x101 0 0 0 8 > param; echo 1 > start;

RI-2020.5-linux 编译器需要向购买开发板的商家/代理提交申请，需要提供自己的HIFI5 DSP Xtensa Xplorer的证明

@zifeiyu 那为什么pack打包到固件的有，刷进去就没了，是不是刷写到emmc但是TF卡启动了？

请贴出LOG，截图

@lyg116 已更换镜像解决结贴

@wanglang 赞。👍 👍

@fanhuacloud 的确是这样的，谢谢大佬

@yuri123088 加我qq: 535888978 我发开发环境运行脚本给你，这个问题应该可以解决。

搞明白了，这两句配置搞得问题：
CONFIG_BCMDHD_FW_PATH="/etc/firmware/fw_bcmdhd.bin"
CONFIG_BCMDHD_NVRAM_PATH="/etc/firmware/nvram.txt" \

@whycanservice 感谢！
