The clk command cannot provide useful output without a clock driver. So let it depend on CONFIG_CLK. Since commit 258c100 ("cmd: clk: Use dump function from clk_ops") the remark about deprecation is obsolete. Remove it. Since commit 7ab418f ("clk: add support for setting clk rate fro...

In uboot, use clk dump to query the llce_can_pe clock. The device tree of atf is configured with 40MHZ, which seems to be fine, but why is the value 0? ATF dts config: mc_cgm0: mc_cgm0@40030000 { compatible = "nxp,s32cc-mc_cgm0"; reg = <0x0 0x40030000 0x0 0x3000>; ...

如果用系统初始化的RCC程序可以正常运行调试,但引用自己配置的RCC(如下) 会出现“JTAG调试不能全速运行,单步调试会卡在RCC_SYSCLKConfig()”的情况,始终找不到原因。 这里除了自己配置好RCC还需要在其它地方设置什么吗?请各位大神指导一下,谢谢! void RCC_Configuration(void) { ErrorStatus HSEStartUpStatus; RCC...
