How do I start the PER clock? U-boot won't boot

‎2024-08-12 04:27 PM

I never heard about the PER clock. I'm looking inside CubeMX, but I don't see any PER clock at all. I guess it's periferial clock. So how do I start it?

 

My U-boot won't boot. I guess that if PER will be like 24 MHz, then U-boot will continue. Or am I wrong?

@Erwan SZYMANSKI 

Hi! It seems that I have the same clock configuration. So this means it must be a bug?

Skärmklipp.PNG

Here is my device tree for Op-tee. Do you see something suspect? ;)

 

&rcc{
	pinctrl-names = "default";
	pinctrl-0 = <&rcc_pins_mx>;
	status = "okay";

	/* USER CODE BEGIN rcc */
	/* USER CODE END rcc */

	st,clksrc=<
		CLK_CKPER_DISABLED <------------
		CLK_ETH_PLL4P
		CLK_SDMMC12_PLL4P
		CLK_STGEN_HSE
		CLK_SPI2S23_PLL3Q
		CLK_I2C46_HSI
		CLK_USBO_USBPHY
		CLK_CEC_LSE
		CLK_I2C12_HSI
		CLK_UART24_HSI

 

After fix:

By the way! CubeMX will clean the whole U-boot-mx.dts file in the device tree when I'm generating new code. It's two bugs counted now! Try it your self. Create and STM32MP151AAC3 project and write something within BEGIN and END commands of the U-boot-mx.dts file inside the DeviceTree folder. Then generate. See if it's disappear.

Hello @DMårt ,
Yes this is peripheral clock, you can find related information in the Reference Manual (RCC chapter).

For the CubeMX configuration, you say that the PER clock is not inside, I am a bit surprised. Can you please double check, I can see this on my side (taken with the STM32MP157F-DK2 example project) :

@Erwan SZYMANSKI 

Oh, it's called CKPER clock. Intill check. I very sure it exists for MP151.

It might be the issue, i guess.

 

I will reply later.

Hi @Erwan SZYMANSKI 

Did you know there is a STM32MP151 board that is based on STM32MP157D-DK1. It's OK if the ST dev team want to build this board and use it to debug the device tree for the 151 processor. Right now, i have seen a lot of bugs inside the device tree for the 151 processor. I guess the dev team is only using 157 and 135.

Feel free to use this. I have build a device tree for this project.
