+=================

+
+The `NUCLEO-C562RE <https://www.st.com/en/evaluation-tools/nucleo-c562re.html>`_
+is an STM32 Nucleo-64 board featuring an STM32C562RE microcontroller with
+512 KiB of Flash and 128 KiB of SRAM.  The board includes an ST-LINK-V3EC
+debugger and programmer with a virtual COM port.
+
+Clocking
+========
+
+NuttX uses the board's 24 MHz HSE oscillator as the PSI reference and runs the
+CPU, AHB, and APB buses at 144 MHz.  The board also has a 32.768 kHz LSE
+oscillator.
+
+Configurations
+==============
+
+nsh
+---
+
+Configures a small internal-flash NuttShell image with USART2 as the serial
+console and the green status LED enabled.
+
+jumbo
+-----
+
+Enables a broader set of NuttX features for additional build and runtime
+coverage.
