I made a custom board with the processor STM32MP151AAC3 and own firmwire https://github.com/DanielMartensson/STM32-Computer/tree/main/STM32CubeIDE/STM32-Computer-Firmware . I have compiled the TF-A by using STM32CubeIDE. It was some bugs with the TF-A configuration, but it seems I fixed them in this thread:

PANIC at PC : 0x2ffec98b
Exception mode=0x00000016 at: 0x2ffec98b
I have tried to flash it with firmware of STM32MP157 with another I2C4 pin configuration. And it failed.

That means the following:
- The HSE clock is working
- The HSE clock is soldered correctly
- The I2C is working, even if it was not ready for communication (wrong pins)
Question:
This new error must lead to an answer. What can it be?

I found the solution! The solution is this.
Add this to your stm32mp15xx-<project name->-mx.dts inside the tf-a device tree.
/* USER CODE BEGIN includes */
#include "stm32mp15xx-dkx.dtsi"
#include "stm32mp15-pinctrl.dtsi"
/* USER CODE END includes */and this
/* USER CODE BEGIN root */
aliases {
serial0 = &uart4;
};
chosen {
stdout-path = "serial0:115200n8";
};
/* USER CODE END root */
clocks {
/* USER CODE BEGIN clocks */
clk_hsi: clk-hsi {
clock-frequency = <64000000>;
/* USER CODE BEGIN clk_hsi */
/* USER CODE END clk_hsi */
};
clk_lse: clk-lse {
clock-frequency = <32768>;
st,drive = < LSEDRV_MEDIUM_HIGH >;
/* USER CODE BEGIN clk_lse */
/* USER CODE END clk_lse */
};
clk_hse: clk-hse {
clock-frequency = <24000000>;
st,digbypass;
/* USER CODE BEGIN clk_hse */
/* USER CODE END clk_hse */
};
/* USER CODE END clocks */
};Last thing is to add cpu1 inside the stm32mp151.dtsi file in the fdts folder inside tf-a folder. Or else, you get one error when you're compiling.
cpus {
#address-cells = <1>;
#size-cells = <0>;
cpu0: cpu@0 {
compatible = "arm,cortex-a7";
device_type = "cpu";
reg = <0>;
nvmem-cells = <&part_number_otp>;
nvmem-cell-names = "part_number";
};
cpu1: cpu@1 {
/* EMPTY */
};
};Anyway!
With my FlashLayout, I only run to Id = 0x8 because I haven't done any more.

- My STM32MP151AAC3 can communicate with my PMIC.
I think that the memory configuration is not correct, because I have 4GB RAM.

Hi @DMårt
Have you moved forward with your board running process? I am in exactly the same place as your log snip shows. I have the following output:

Do you have the same processor as In do?
If yes, check your my custom board. It's working like a charm!

Thank you for the quick reply! I have quite a similar processor, STM32MP151FAD. Is it the correct repository https://github.com/DanielMartensson/STM32-Computer/?

Yes it's the repository. Notice it's for MP15XXAC, but if you copy the device tree and change the pins, then it will work.
Make sure you get the schematic from Circuitmaker as well.

You need to enable debugg for Opt-ee.
Very easy! Go to Makefile.sdk in Optee and change to DEBUG=y and DEBUG_LEVEL=4. It's currently on 2 (I/TC) for the moment.

Thank you! I moved forward but still don't know how to run it. I have a lot of logs, but I can't see anything wrong. Would you look at it and make any suggestions? Sorry for bothering you, but you are the only person who can help me. I can find nothing on the Internet, and the materials are minimal.
I don't know where you are from, but we can drink something if we meet one time ;) Thank you for being so supportive! Please share if you know something you can recommend to learn more about the STM31MP1 series.
I attached the complete log from the booting process.
The problem I have is the flashing process hanging after the 0x3 stage. Please look at the following log:
