回复: OpenixCard - 在 Linux 系统刷写全志镜像到 SD 卡发布在 编译和烧写问题专区
@yunyisa 自制的固件无法打包成全志的镜像，只能由SDK生成，全志镜像有专有的封装格式，不仅仅是地址偏移

回复: 对R128模块原理图的疑问发布在 R128系列-智能硬件
1.AVCC是芯片内部电源供电吗？datasheet上没说。 -- 是芯片内部供电
2.EXT-LDO33不是内部LDO输出么，为什么要外接3V3? -- 外接DCDC降低功耗，减少发热
3.为什么VDD-SYS1与VDD-SYS2、VDD-AON与VDD12-PSM外部要接在一起。 -- R128各模块供电采用内部 PMU
我猜应该有一本完整的硬件设计指南可以解答问题，只是没公开。 -- https://r128.docs.aw-ol.com/hardware/hardware_design/ -
回复: 程序运行之后告诉我有错误发布在 V853系列-AI视觉
@aaa0557li V851S 不能刷 V851SE，不能刷V851S3，ic cant match axp, please check... 是检查固件与芯片型号不对应，另外检查编译环境是否有其他变量导致编译出来的固件检查不匹配，如果都没问题建议重装一个干净的SDK不要与其他SDK复用同一个环境

@nimadibaj
[ISP_ERR]isp_ctx_save_exit, line: 109,open /mnt/isp0_1920_1088_30_0_ctx_saved.bin failed, err:Read-only file system.
这个是暂存isp参数，由于没有文件所以打开失败。可以无视。真正的问题是Got signal 11, exiting ...，程序出现段错误，请检查指针使用

回复: T113S3双路 dual lvds驱动不起来发布在 Linux
uboot和dtsi里面添加dual link IO的配置

&lcd0{ ... lcd_lvds_if = <1>; ... ... pinctrl-0 = <&lvds2link_pins_a>; pinctrl-1 = <&lvds2link_pins_b>; ... }其他和single link的配置方法无异，如果点不亮请检查时序

回复: V853 和 V853S NPU算力差了0.2，这个0.2在具体应用上会有明显的性能差距吗？主要用来做目标检测，静态场景。发布在 V853系列-AI视觉

回复: V851se的u-boot引导发布在 V853系列-AI视觉
会，启动介质优先级描述了每个介质被选择为启动介质的可能性。BROM 首先读取具有最高优先级的介质的 boot0。如果该介质不存在或存在任何问题，BROM 将尝试下一个介质。否则，该介质将被选择为启动介质。

回复: rs485的设备树怎么修改发布在 其它全志芯片讨论区
DE和RO为使能管脚。DE为低电平、RE为低电平时为接收；DE为高电平、RE为高电平时为发送；RO和DI为数据管脚。RO为接收，DI为发送；因此我们经常将DE和RE直接连接，用一个IO口控制。
需要添加以下三个成员：
- sunxi,uart-rs485
- 0：485模式关闭
- 1：485模式使能
- sunxi,uart-485fl
- 0：485 gpio管脚数值为0时表示发送状态
- 1：485 gpio管脚数值为1时表示发送状态
- sunxi,uart-485oe-gpios
- 用于外部转换芯片使能信号的gpio引脚，GPIO_ACTIVE_HIGH含义为默认为高电平
示例：
uart1: uart@2500400 { ... status = "okay"; //添加以下三行 sunxi,uart-rs485 = <1>; sunxi,uart-485fl = <1>; sunxi,uart-485oe-gpios = <&pio PG 8 GPIO_ACTIVE_HIGH>; };A40I 5.10 内核：
uart5_pins_a: uart5_pins@0 { pins = "PH6", "PH7"; function = "uart5"; }; uart5_pins_b: uart5_pins@1 { pins = "PH6", "PH7"; function = "gpio_in"; }; &uart5 { pinctrl-names = "default", "sleep"; pinctrl-0 = <&uart5_pins_a>; pinctrl-1 = <&uart5_pins_b>; rs485-enable = <0>; rs485-mode = <0>; /* defalut 0:rx 1:tx */ rs485-mode-pin = <&pio PH 8 GPIO_ACTIVE_LOW>; status = "disabled"; }; - sunxi,uart-rs485

回复: R128-S2 使用外部1.2VDC的情况下, 如何关闭 APP_LDO发布在 R128系列-智能硬件
@maplerian 在深度休眠下，内部APP_LDO由PWRCTRL硬件关闭，且深度休眠下GPIO控制器断电不会启用DCDC，唤醒时由PWRCTRL硬件逻辑开启内部APP_LDO，然后启用GPIO控制器拉高启用外部DCDC，启用后自动切换到外部DCDC供电

回复: R128-S2 使用外部1.2VDC的情况下, 如何关闭 APP_LDO发布在 R128系列-智能硬件
APP_LDO的关闭是PWRCTRL的硬件行为，由配置处理器
deep sleep mode后，CPU进入WFI触发PWRCTRL的该行为，无寄存器配置。PWRCTRL仅支持手动关闭DSP。外挂DCDC可以通过读取LDO_EN寄存器查看目前是否开启内部LDO -

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。
