新画一块ESP32-C3板子，一运行 wifi 例程就无线重启，SHA-256 comparison failed

[矜辰所致_ESP32C3]

是的，修改代码重新编译下载试试。esp_wifi_start 会调用 esp_phy_load_cal_and_init()， 加些 log 检查一下是不是这个函数没有走完, 是否是 注释掉的那段代码导致的重启。

我截取了一段复位问题log：

看看能否看出什么问题，有人提示我说 wifi 启动影响晶振导致的。

[ESP_LJY]

Code: Select all

E (221) boot: No bootable app partitions in the partition table

这次的 log 和之前不同？ 这句 log 表示没有烧写有效的应用程序。

[矜辰所致_ESP32C3]

Code: Select all

E (221) boot: No bootable app partitions in the partition table

这次的 log 和之前不同？ 这句 log 表示没有烧写有效的应用程序。

我才发现两次不停复位区别不同，但是也是因为没有头绪，导致也没有注意到这些，在有些地方请教了以后，
他们说 ESP-IDF的 DEMO 也可能有些问题的，然后让我更新最新的 ESP-IDF ，我以前用的 V4.3.1 ，去年用了一整年，然后老板子也没遇到问题，也就是最近一个月画了新板子发现了问题。

为什么不用最新版也是因为 乐鑫官方的 VSCode 插件以前更新的进度赶不上 IDF 的更新进度，就是安装新版本总是会有问题。

然后我更新了一下4.3.4 版本，发现不重启但是连接不上 wifi ，然后我又更新了一下 4.4.2 版本的 IDF，然后目前看来就正常了。

大哥，能否指点一二，我这种可能是什么问题吗？ 我已经确定了不是电源供电不足的问题，有人说是wifi 启动的时候影响了晶振，SDK 初始化的时候以前的判断可能有欠缺。 不知道是不是这种问题？

如果大哥能够指点一下，对以后板子设计也有帮助啊，硬件上面能避免的最好就硬件避免了。

关注一下！

我也遇到了这个问题了，跟SHA-256没关系，也跟供电没关系，只要WiFi连上就会触发重启。试过代码注释掉WiFi初始化的流程，板子则能稳定的正常跑不会重启。同样的板子，刚开始是不会重启的，跑了20分钟左右也会出现重启现象。现在是一连上WiFi就会出现，不知道是否WiFi那个地方干扰了芯片的稳定性，需要大佬指导下。

可以嘗試這兩個改動：
1. 在sdkconfig 把wifi max tx power 降低
2. 在sdkconfig 關閉使用newlib

[IvanLi]

我也遇到同样的问题，不过我感觉，好像是和供电关系，我并了个 470uF 的电容，连电脑供电就稳定。 或者换供电的电源表现也会不同。连 USB HUB 时，给额外供电也能稳定很多。

有时候重启时，手摸模块有概率能挺过WiFi连接。我感觉是供电问题，但是我也不确定。。

有降低 Wi-Fi 的 TX power 吗？

[FengZhaolin]

我遇到了一模一样的问题。可以确定的信息有：

1. 当初始化 wifi 时，CHIP_EN 会被瞬间拉低，从而导致重启。示波器能看到明显拉低。
2. 当插上wifi天线时，不会出现这个现象。（或者用金属接触SMA插座的针脚，也不会）
3. 当拆掉RF相关的电容和电阻，不会出现这个现象。
4. 基本可以排除供电的问题，因为用商用的可调电源，现象一致。

RF 天线的电容和电感值（从chip到SMA的方向）是：2.7qF, 2.7nH, 2.0pF 。显然手摸或者接入天线的时候，改变了电容值，从而解决了问题。

哪位大神可以解释下原理？

[IvanLi]

我觉得就是供电问题。模块供电或者芯片 VDD3P3 单纯堆电容容值就没事。我现在不用模块了，用自己画的板子加芯片没再遇到这个问题了。
