我的板子触摸芯片是NS2009，写好了touch驱动，触摸也有数据，但是屏幕就是不动

Init OK
Boot to SPI mode
Copy Flash offset 64 to RAM 0x8000000 size:366124
Copy Flash Ok!
Goto 0x80000000 ...如果直接FEL模式启动时是正常的。我使用spiflash-read读出代码的前面1K字节，对比了下是完全一样的。
请问你遇到过这个坑吗？
我也遇到同样问题
Init OK
Boot to SPI mode
Copy Flash offset 64 to RAM 0x8000000 size:366156
Copy Flash Ok!
Goto 0x80000000 ...flash 型号 xt25f128b
把RT_SFUD_SPI_MAX_HZ 改为33M还是启动不了...
遇到同样问题，之前还好好的。make clean也不行

卡在start kernel 这里会是什么问题导致的？
和你一样，请问有解决吗？
