The following lists some common problems according to the form of Q&A, please try to find a solution in the following if you find any problem when using it, if the above record doesn't solve your problem, you can try to ask the question in [Community](https://maixhub.com/discussion), reasonable questions will be answered by the technical staff for you. | ||
|
||
## General Question | ||
|
||
**Q:**There are some functional defects when using the logic analyzer/DAPLink/JLink/serial port module. | ||
|
||
**A:**Please try to find and resolve your issue first in the Q&A section. If the problem persists, click [here](./update_firmware.md) to update the firmware and try again. | ||
|
||
|
||
**Q:**The LED doesn't change after pressing the button? | ||
|
||
**A:**Check that the interval between key presses is not less than 100ms, otherwise it may cause the module to enter boot mode and you will see that LED no longer change. If this occurs, re-power up the module to restore it | ||
|
||
## Logic Analyzer | ||
|
||
**Q:** After clicking "run", the prompt "device closed but should be open." | ||
|
||
![image-20230816113213933](./../../../zh/logic_analyzer/combo8/assets/use_logic_function/tips_capture_failed.png) | ||
|
||
**A:**This may be the result of unstable contact that causes the device to disconnect, try to re-plug the device and then reconnect it to solve the problem. | ||
|
||
**Q:**When using 8-channel sampling, it was found that waveforms also appeared when the D7 channel was not connected. | ||
|
||
**A:**This is a problem to be solved, but this problem will not affect the sampled waveforms, and the waveform can still be acquired normally after connecting an external signal to the D7 channel. | ||
|
||
**Q:**When sampling waveforms, the waveforms in the display window do not match the actual waveforms. | ||
|
||
**A:**Make sure that you connect the GND wire of the logic analyser to the GND of the target device, and make sure that the GND wire is as close as possible to the location of the point to be measured. Be aware that even at a distance of 1cm, there may be many components in between that can interfere with the signal, so even 1cm closer is likely to give better signal quality. | ||
|
||
**Q:**Logic analyser can't sample for long periods of time | ||
|
||
**A:**There are multiple situations: | ||
|
||
**Situation 1:** Sampling time is very small due to incorrect setting of sampling points and sampling rate, sampling time (unit:s) = sampling points/sampling rate, please make sure that the sampling points and sampling rate are set correctly. | ||
|
||
**Situation 2:** Effect from PC performance. As PulseView needs to use a lot of USB bandwidth, but if the PC performance is poor at this time, it will also result in shorter sampling times. | ||
|
||
**Situation 3:** If everything is fine, check if the number of sampling points is set too large, resulting in a memory overflow that prevents sampling | ||
|
||
|
||
|
||
## DAPLink | ||
|
||
**Q:**MDK can't find DAPLink device | ||
|
||
**A:**It is possible that the MDK version is too low, and a low version of MDK may not be able to recognise DAPLink (the MDK version used for testing in this article is V5.38). If the MDK version is too low to recognise DAPLink, if you don't want to upgrade the version, you can refer to the method [here](https://developer.arm.com/documentation/ka003663/latest/) to update the debug driver of CMSIS-DAP. | ||
|
||
**Q:**The serial port function in DAPLink mode does not work properly and messages are echoed back | ||
|
||
**A:**Please refer [here](./update_firmware.md) to update the firmware to the latest version before trying again | ||
|
||
|
||
## CKLink | ||
|
||
None | ||
|
||
|
||
## Serial Module | ||
|
||
**Q:**The serial terminal cannot open the serial port. | ||
|
||
**A:**Try using a different serial terminal. For Windows, you can try using XCOM, and for Linux, you can try using Minicom. | ||

以下按照Q&A的形式列举了一些常见的问题,使用过程遇到任何问题时请在下文中尝试寻找解决方法,如果上述记录并没有解决你的问题,可以尝试在[社区](https://maixhub.com/discussion)中反馈该问题,合理的问题会有技术人员或其他开发者为您解答。 | ||
|
||
## 综合问题 | ||
|
||
**Q:**使用逻辑分析仪/DAPLink/CKLink/串口模块时有部分功能异常 | ||
|
||
**A:**请优先在Q&A中尝试找到并解决你的问题,如果仍有问题,则点击[这里](./update_firmware.md)更新固件后再尝试 | ||
|
||
|
||
|
||
**Q:**按下按键后,指示灯没有变化? | ||
|
||
**A:**检查是否按下的频率太快,按下按键的间隔不要小于100ms,否则可能导致模块进入boot模式,现象会看到灯不再变化。如果遇到了该情况,尝试重新上电即可恢复 | ||
|
||
## 逻辑分析仪 | ||
|
||
**Q:**点击run后弹窗提示"device closed but should be open" | ||
|
||
![image-20230816113213933](./assets/use_logic_function/tips_capture_failed.png) | ||
|
||
**A:**这可能是接触不稳定导致设备断连了,尝试重新插拔设备后再重新连接即可 | ||
|
||
**Q:**使用8通道采集时发现D7通道在悬空时也会出现波形 | ||
|
||
**A:**这是一个待解决的问题,但这个问题不会影响采集波形,给D7通道接入外部信号后仍然可以正常采集波形。如果不需要这个通道时也可以隐藏这个通道,很抱歉给您带来了困扰。 | ||
|
||
**Q:**波形采集时,波形显示窗口中的波形和实际的波形不一致 | ||
|
||
**A:**请确保将逻辑分析仪的GND线连接到了目标设备的GND,并且确保GND线离待测点的位置越近越好。要知道即使是1cm的距离,中间也可能有很多元器件会干扰信号,所以哪怕是更近1cm也有可能让信号质量更好。 | ||
|
||
**Q:**逻辑分析仪无法长时间采样 | ||
|
||
**A:**有多种情况影响无法长时间采样: | ||
|
||
**情况1:**采样点数和采样率设置不正确导致采样时间很小,采样时间(单位:s)=采样点数/采样率,请确保采样点数和采样率设置正确。 | ||
**情况2:**PC性能的影响。由于PulseView需要使用大量的USB带宽,但是如果此时PC本身性能不足,也会导致采样时间变短。 | ||
**情况3:**PC内存的影响。如果一切都正常,那么检查一下是否是采样点数设置太大,导致内存不足以保存采样数据 | ||
|
||
|
||
|
||
## DAPLink | ||
|
||
**Q:**MDK找不到DAPLink设备 | ||
|
||
**A:**有可能是MDK版本过低的原因,低版本的MDK可能无法识别DAPLink(本文测试使用的MDK版本是V5.38)。如果MDK版本低导致无法识别DAPLink,但是不想升级版本,可以参考[这里](https://developer.arm.com/documentation/ka003663/latest/)的方法来更新CMSIS-DAP的调试驱动 | ||
|
||
**Q:**DAPLink模式的串口功能无法正常使用,出现回显的情况 | ||
|
||
**A:**请在更新固件章节中将固件更新到最新版本后再尝试 | ||
|
||
|
||
|
||
## CKLink | ||
|
||
None | ||
|
||
|
||
|
||
|
||
## 串口模块 | ||
|
||
**Q:**串口终端无法打开串口 | ||
|
||
**A:**尝试一下其他的串口助手,Windows上可以尝试使用XCOM,Linux上可以尝试使用Minicom | ||
