Hi, 

I have customized a board using STM32MP157DAC referencing the mp157d-disco board hardware design. I have discrete power supply. I deleted the PMIC related nodes is DT and add fixed regulator in the root. The TF-A boot is ok, but the optee panic with the error message below:

@xchen, please try it. Change the values inside the following regulator to both on 1350000. This one simple change solved my issue. If not, please share your clock configuration or an ioc file.

 

vddcore: vddcore {
		compatible = "regulator-fixed";
		regulator-name = "vddcore";
		regulator-min-microvolt = <1200000>;
		regulator-max-microvolt = <1350000>;
		regulator-always-on;
	};

 

What MPU frequency do you have in the clock configuration? The configuration below works in my case. I set the MPU frequency to 800 Mhz.

 

vddcore: regulator-vddcore {
	compatible = "regulator-fixed";
	regulator-name = "vddcore";
	regulator-min-microvolt = <1350000>;
	regulator-max-microvolt = <1350000>;
	regulator-always-on;
};

&cpu0 {
	cpu-frequency = <800000000>;
	cpu-supply = <&vddcore>;
};

@xchen I have an idea of how you can solve your issue. First, you have to enable debug logs in the OPTEE Makefile. My problem was caused by the wrong clock configuration and CPU frequency, and the debug log described the reason in detail.

I couldn't enable debugging by command parameters, so I had to make a few changes to OPTEE's Makefile, specifically the EXTRA_OEMAKE variable.

CFG_TEE_CORE_LOG_LEVEL=4 CFG_TEE_CORE_DEBUG=y

Please enable debug and share the entire boot log. I will try to help based on my own experience :)

@rgruberski , thanks for help.

I have the detailed log info. I think the error occurred here, it seems like a discret power node problem:

Do you have idea how to fix it? I enclosed my optee device tree and the entire boot log.

@xchen You're welcome! I am so glad it helped. Please let me know if you will have any issues. I almost ran my custom board :)
