Development board hardware: Functional diagram 6-layer PCB design, open source, YYDS

The main control chip is: The STM32U585 microcontroller uses an Arm Cortex-M33 processor core running at 160 MHz, supports TrustZone technology for the Armv8-M architecture, DSP and floating point unit (FPU), and expands the STM32 ultra-low power product series and its performance. In addition to providing 2 MB on-chip Flash memory, the STM32U585 also provides additional hardware encryption acceleration engines (AES, PKA and OTFDEC).

The development board should come with its own system. The test is as follows:

Tera Term is a serial port debugging tool from abroad with a simple interface and practical functions. It is a terminal emulator for Microsoft Windows, supporting serial ports, remote login and SSH connections, and a built-in macro scripting language.

Tried STM32CubeProgrammer, but STLINK was not recognized. The next step was to test Keil or IAR programming.

The USB is plugged into the port on the right. My STM32CubeProgrammer works normally, but when I use STM32CubeIDE 1.7.0, it prompts me to upgrade. I have upgraded it.

Try to see if you can upgrade.

The wiring is dense and looks good.
