How Can I Find The Root Cause Of A System Problem With SPI Devices?

Our test results show a repeated error while programming M95128-R EEPROMs. The EEPROMs are located on separate panels. To program these SPI devices, we use relays and the SPI Host Adapter. 

So far, we have been unable to identify and resolve the root cause of this consistent problem. How else can we analyze and remedy this issue? Are there other tools and techniques to consider? There you can consider Flash Programmers for 8-32 bit custom MCUs & SPI Flash Memory.

Recommendations to Successfully Analyze the Root Cause

There are various methods to obtain the details you need to understand and resolve the issue that has been occurring with your setup. One method involves reproducing your system in a more controlled environment. Another method is monitoring the traffic of your system – identifying the root cause by gathering and filtering real-time data.

Prototyping the System

We suggest using our I2C/SPI Activity Board for your scenario. This should help you create a prototype of the system and act as a tool for debugging a system against working slave devices. This approach can help differentiate between hardware and software bugs. The activity board is also useful for establishing a baseline for software commands and responses. 

Monitoring Real-time SPI Transactions

Depending on the complexity of your system, you may need more details to fully understand the cause of error and failure.  In addition to the  I2C/SPI Activity Board,  we recommend also using  Beagle I2C/SPI Protocol Analyzer with our Data Center Software, which you can easily integrate into your setup. 

This powerful and cost-effective set of tools will enable you to monitor the flow of data on the bus, facilitating real-time monitoring along with diagnostics and communication. Please look at our video that demonstrates how the Beagle I2C/SPI Protocol Analyzer can be used to quickly analyze and debug a system.
