Description
The board is stuck after powering down and then powering on, and the board freezes in the spi flash initialization after pressing reset. Re-burning other normal Apps after resetting and then burning the App function can work normally.
板子掉电再上电后卡死，按复位后卡住在spi flash初始化。重新烧录其他正常App复位后再烧录该App功能都可正常运行。
RTThread版本4.0.5，MCU使用F411CC，onchip flash 256KB，RAM 128KB。

Research direction
Start by reproducing the power-down/power-on and reset sequences on the F411CC with RT-Thread 4.0.5, watching the rt_hw_spi_flash_init entry point shown in the boot log. Compare behavior after re-burning the affected App and other normal Apps; the issue is resolved when the board no longer freezes during SPI flash initialization after reset or power cycling.
