【STM32MP135F-DK】Get familiar with the STM32MP135F-DK exploration kit and development environment [Copy link]

1. STM32MP135F-DK Unboxing
   I received the STM32MP135F-DK development kit with great excitement. This is my first time using an STM32 board that can run Linux. The outer box is very crafted. Inside is an instruction manual, a flat cable, and the main part of the exploration kit wrapped in an anti-static bag.
   
   
   After unpacking the bag, there is a camera module, the STM32MP135F-DK kit body, and a bag with a 16G TF card attached to the screen. The role of the TF card here is similar to that of the Raspberry Pi's TF card. After the dip switch is set, it can be booted from the TF card, and the file system may also be stored in it
   
2. Quick Experience
   In order to quickly experience the STM32MP135F-DK Discovery Kit, we need to prepare two data cables, one USB Type-C data cable, the interface is on the right side of the development board; one micro USB data cable, the interface is on the left side of the development board. It should be noted that the official recommended power supply for typec is 5V/3A power input. Problems with the power supply voltage may cause the device to fail to start or even damage.
   We inserted the TF card and connected it, and the display effect is as follows.
   
   The development kit screen is touch-sensitive. After a simple test of the various functions, I was surprised. Is this still STM32? It's so powerful!
   
   After connecting the micro USB, a new serial port and ST-LINK device appeared on the computer.
   
   Let's connect with putty and take a look at the system configuration
   
   
   
   You can see that there is an ARMv7 core, a Linux 5.15 kernel burned, dual Ethernet cards, and a USB network card.
3. Development environment construction

My computer is win10+WSL2 (Ubuntu 20.04), so I plan to install STM32CubeProgrammer directly under Windows and compile the system and applications in wsl2.

First, download STM32CubeProg from the ST official website and select the software version according to your system. The official website address is: https://www.st.com/zh/development-tools/stm32cubeprog.html

After the download is complete, install it, select the installation path, and click Next.

After the installation is complete, continue to download the SDK from the official website, which includes the image, source code and compilation tool chain. Official website address: https://www.st.com/zh/embedded-software/stm32mp1dev.html

Later we can do further development and testing based on SDK

For dual-core devices, where does the boot process begin?

Generally, it starts from bootrom, and starts cpu0 first.

It seems that STM32MP135F is a single-core device. If it is a multi-core device, there are two cases, one is two high-performance cores and the other is a heterogeneous core. The heterogeneous core is not driven by Linux by default.

Well, the STM32MP135F only has a single-core Cortex-A7, while the 15 series has dual-core
