我用着感觉挺快的啊，你是不是设置有问题，我是直接用的demo然后改的自己的驱动 例程里面用了dma，不知道是不是因为这个，psram_init(PSRAM_CLK_SEL_COREH_192M);这个改成最高的，再试试，我之前不知道芯片内部有psram，我用ram直接驱动lvgl也是慢的蜗牛一样

FR8008GP-U RTC例程有没有？

使用FR8008GP-U LVGLDemo创建控件反复重启
工程：fr8000u_sdk\examples\evm\gui_demo_8_1_BLE
修改部分：将蓝牙，PSRAM部分和触摸都去掉了，初始化LVGL和LCD7789驱动都没问题，只要我创建LVGL控件，芯片就会复位

屏蔽掉创建按键就不会复位了，是不是栈和堆溢出，如果是在哪设置呢

@yjx 可以正常下载程序，但是无法使用这个工具

使用rtt，没法打开rttview



要怎么使用他，这是我在jlinkdevices里面添加的

FR8008GP-U LVGL的例程在哪？
