DDR1 clock problems, DDR1 clock Problems

I encountered a problem recently. I had a hard time tossing for a week and had a special crash! When the board is powered on, when reading data from Flash, sometimes an error occurs when writing data to DDR. For occasional errors, it is difficult to use reveal to locate the error online, and the location of each error is not the same.

Today, the hardware engineer told me that I could reduce the frequency, reduce the DDR1 clock to 90 MHZ, and reduce the operating clock from NAND_FLASH to 90 MHZ. The surprise is that the problem has been solved !!

Conclusion: In the debugging process, we have encountered some random events. We should discuss the hardware issues with hardware engineers. In this way, we can better solve the problem!
