openjtag on soliddigi spruce stm32 arduino board
DESCRIPTION
Spruce -SolidDigi STM32 ARM cortex board can be used with OpenJTAG and is compatible with mini ARM cortex-M3 board .It can be used in GCC+Eclipse+openocd+openJtag and Arduino enviroment!Spruce has Arduino compatible shield pins, all the Arduino shields can be used on SolidDigi STM32 cortex board. Arduino similar IDE can be used to download Arduino code to Spruce board.Spruce Hardware Resources:Including 2.4" TFT LCD Touchscreen, diamension of LCD screen CPU: STM32F103VET6, TQFP 100 pins FLASH£º512K BYTES, SRAM:64KBYTES 1 JTAG debug interface 1 power LED indicattor (Green), 1 status LED (Blue) 1 RS232 port, Need crossover cable to talk to PC Support 3 pin ISP 1 USB2.0 SLAVE port 1 Micro SD(TF) slot, uses SDIO 1 2.4 inch TFT (240X320 (touch screen) ), use FSMC 16 bits interface to control 1 SPI interfaced AT45DB161D(2M BYTES) serial FLASH 1 functional botton 1 RTC battery socket 1 RJ45 Ethernet port All unused GPIO pins are connected to external headers.TRANSCRIPT

Poll: poll spruce status
Halt：stop the spruce board
Stm32x mass_erase 0: mass erase flash
Flash write_image hex with file full path: write program to flash
Reset: reset the spruce
Note: stop the development board, mass erase, and then write the program to flash.
