器件型号：PROCESSOR-SDK-AM335X 工具/软件：
您好：
我使用 AM335x 创建了电路板、并使用 SDK 工具通过硬件修改 U-Boot 和内核。 u-boot 正确启动我并尝试初始化内核。
问题是当内核尝试启动时,我有很多错误的时钟和计时器和系统停止启动。

对于硬件、我使用了与 AM335x-EVM 相同的元件和连接、并连接 SYSBOOT [15：14 ]= 01b = 24MHz。
我查看了有关 Board_Port 的所有文件（假设在创建电路板时要复制）(https://software-dl.ti.com/processor-sdk-linux/esd/AM335X/09_03_05_02/exports/docs/linux/How_to_Guides/EVM/U-Boot.html#integration-support-for-a-new-board-intro-the-u-boot-tree) 、我只找到了以下与时钟和计时器有关的项目。
&rtc {
clocks = <&clk_32768_ck>, <&clk_24mhz_clkctrl AM3_CLK_24MHZ_CLKDIV32K_CLKCTRL 0>;
clock-names = "ext-clk", "int-clk";
};
/* Clock Defines */ #define V_OSCK 24000000 /* Clock output from T2 */ #define V_SCLK (V_OSCK)
因为我找不到为时钟和计时器充电的元素、我可能会发生什么情况？
谢谢、
