Thank you for your reply.

There are three sample boards with the same issue. When this problem occurs, testing the 24MHz crystal oscillator frequency and 3.3V/1.8V power output is normal. We speculate that the program stopped at this point due to some internal initialization issues within the chip, and more log information can accurately locate the problem point.

There are two questions that need to be confirmed:

1. The data manual mentions that we need to perform software leveling for DDR3. Is this necessary?

2. There is a procurement question: How can we purchase the latest chip version? How long is the manufacturer’s chip warranty period?
