你好，请教个问题
单板类型：YTM32B1HA
Wdg_Demo 这个里面有个延时的函数 ，发现不生效 ，也不知道看门狗生效没，系统有无重启
延时函数是（demo生成的）：

这个延时不管填多少，打印出来的时间戳都是一样的。
打印时间的也是调的系统函数

简介

目前云途芯片 YTM32B1ME05 与 YTM32B1MD14 支持对欧司朗灯珠的驱动控制。
MCU 在完成对灯珠的初始化后，即可对任意灯珠进行控制，例如改变颜色，亮度等，实现各种灯效。
osire.mp4

配置参数

灯珠通过串行总线控制，目前 MCU 通过 SPI 来实现对灯珠的控制，所以需要使能对应 SPI 的时钟，以及配置相关引脚，另外 DMA ，lpTMR 与中断优先级也需要配置，这些在示例中有配置，下面详细介绍一下引脚相关的配置（peripherals_osire_config.c）。

当前的配置中，第零条灯带用 SPI4 来传输，第一条灯带用 SPI2 作传输。
PTC14 作为 SPI2_PCS0，记录一下它的 PINMUX(3)，以及它的 PCTRL 地址，即 PCTRL->PCR[14]
PTC15 作为 SPI2_SCK，记录一下它的 PINMUX(3)，以及它的 PCTRL 地址，即 PCTRL->PCR[15]
ee08646c-e2f1-43d1-94fc-b3b3d16564dd-ODE0bJgE2oyvc0x8I2scidNQnIf.png
此外，pinmux 中也得修改其引脚，PTC1 作 SPI2_SOUT，
1c1fc067-b708-4fec-9b21-b7b8faa694ea-KuCPbHSqdoxCnOxJ11Icyo38nzd.png
调用灯控相关API 时，有个参数是 StripNr，例如复位。若想复位第一条灯带，将 StripNr 设置为 1，就会使用 SPI2 向灯带发送复位指令

上述引脚配置需要根据实际硬件进行调整。 编译

目前灯珠驱动包以静态库的形式释放，支持 CMakeGCC，KEIL，IAR，YuntuIDE。可以通过 YT Config Tool 生成对应 IDE 的工程，随后添加静态库进行编译。关于在不同 IDE 下如何添加静态库，可参考该附件

1、SDK应用_Secure_Boot 模块配置及应用 此文档中 需要配置BVT，我想问下APP中需要和这个保持一致吗？里面的设置的信息是什么样子的？025f9dbb-1d42-4b0f-ba74-91b6f42a1790-image.png
2、boot_prepare是加载秘钥的。boot_demo是bootloader？用户的app yt需要怎么去设置啊。
3、有demo演示如果我的秘钥泄露了 我怎么去修它。

点击更新后就一直停留在下图界面，没有弹窗install，重启重更都没用

低功耗配置为standby模式，文档说standby模式下要配置GPIO时钟源为SXOSC才能正常实现唤醒，为什么我没配置GPIO时钟源也可IO中断唤醒standby。

我需要使用矩阵运算在SDK中找到了的矩阵相关的运算库，我把它添加到CMSIS目录下，并手动添加引用文件后，添加后使用YCT修改配置后，手动添加的引用会被覆盖清除掉，但我不想将文件移动至其它地方，因为它属于CMSIS的一部分，有什么方法可以解决呢？

欢迎使用3.1.0YT Config Tool（YCT), 下面是本次版本的更新内容，希望您在使用过程中有更好的体验。一些主要的更新内部包括：

Highlight AI FAE 功能

寻求基于MCAL的MCU睡眠电流测试例程，最好用LPTMR定时器实现polling(run--standby来回切换，run的时间特别短的那种）

我在原来 can 模式基础上添加了 fd 发送支持，目前发现无法正常发送数据。具体关键代码如下：

相比原来的 can ，主要增加了修改 CAN0_FDCBT 和 CAN0_CBT（之前用的 CAN0_CTRL1），以及寄存器CAN0_FDCTRL和CAN0_MCR开启canfd。
canfd报文发送时，追加了 EG32(CAN0_MB0_HEAD0) |= 0xC0000000;。

帮我看看这是什么问题， 我用J-FLASH刷固件， 提示的这个消息。

在使用ytm32b1le05，boot和app共用FEE区域，boot初始化后没有诊断请求，跳转到app后，app初始化FEE跳转之前标志位读写可以正常使用，在1002服务reset后boot初始化FEE在FEE_WAIT_DONE进入到DefaultISR（）是为什么。0209c415-0f4b-41b0-8a4f-7f9fd54b3b1c-image.png

比如修改某些简单的代码，导致section 段大小有改动，并通过YT Config Tool 生成签名，发现此代码无法启动，通过调试代码是没问题的

修改随机数的demo。我将size改为0x20的时候。FCT_VAL寄存器值会变为0 。随机数就停止了。

有大佬能帮忙看下吗
