STM3210E EVAL Platform HAL

Description

The STM3210E-EVAL board consists of a STM32F103Z microcontroller, 1MiB of external SRAM, 16MiB NOR flash and 64MiB NAND flash. It has connectors for two UARTs, I2C, MicroSD, USB, CAN, JTAG and various other devices.

For typical eCos development, RedBoot or a GDB stub image is programmed into internal FLASH and the CPU boots directly into that. It is then possible to download and debug stand-alone and eCos applications via the gdb debugger using UART0. Alternatively test programs may be downloaded and debugged via a JTAG debugger attached to the JTAG socket.

This documentation describes platform-specific elements of the STM3210E-EVAL board support within eCos. The STM32 variant HAL documentation covers various topics including HAL support common to STM32 variants, and on-chip device support. This document complements the STM32 documentation.

Supported Hardware

The STM32 has two on-chip memory regions. A RAM region of 64KiB is present at 0x20000000. A FLASH region is present at 0x08000000 and is aliased to 0x0000000 during normal execution. On-board memory consists of 1MiB of SRAM mapped to 0x68000000 and 16MiB of NOR FLASH mapped to 0x64000000.

The STM32 variant HAL includes support for the five on-chip serial devices which are documented in the variant HAL. UART0 and UART1 are connected to external connectors on the board marked "CN12" and "CN8" respectively. Only UART1 on CN8 is equipped with RTS/CTS lines.

Tools

The board port is intended to work with GNU tools configured for an arm-eabi target. The original port was done using arm-eabi-gcc version 4.3.2, arm-eabi-gdb version 6.8, and binutils version 2.18.
