It can result from hardware problems or setting programming problems.
- Image setting error: Confirm whether the read and write mode of the QSPI chip and the burn tool match, especially whether the correct mirror is selected at startup. You can try modifying the mirror options or changing the burn tool.
- 2. Hardware fault: Check whether the QSPI interface is correctly connected, whether there is a short circuit on the PCB tracks, and whether there is a problem such as virtual welding. You can check the line or replace the QSPI chip or the main control board.
- 3. Power supply problem: Confirm whether the power supply is sufficient and stable, you can use an oscilloscope to monitor whether there is fluctuation or interference in the power supply. You can replace the power supply or add a filter circuit to solve the problem.
- Program error: Check whether the code is correct, whether it is compiled successfully, and whether it is compatible with the hardware. You can use other QSPI burn tools or downloaders to burn and verify that the problem is not present in the burn program.
- QSPI chip memory chip problem: Check whether the QSPI chip is damaged, you can use other burning tools or downloader to burn and confirm whether the problem appears on the QSPI chip.
