-# STM32F103C8T6 Dev. board
-## Overview
-{{ :arm:stm32f103c8t6:board.jpg?direct&200|Board top view}} I have had this board on a shelf for quite some time, but never used it before. Having nothing better to do this week-end, I gave it a try, and here is what I've found/done.
-It's a small development board, with a 20 pins JTAG connector, a MiniUSB connector and all (?) pins broken out on two rows on the side.
-There's a 8Mhz quartz (with PLL, the chip can run at 72Mhz), a 32.768kHz quartz (for the RTC), and that's pretty much all, but for only 10 bucks... It's okay =)
-## Bootloader
-The board is shipped without any software, link, datasheet, or pre-loaded code. Luckily, the STM32 family chips often (always ?) embed a bootloader. For this chip, STM32F103C8T6, it's a Serial bootloader, which can be accessed on the top left UART header (the 4 pins next to the USB port).
-I have tried flashing it with the SWD (that can be found in the JTAG header) with an ST-link programmer. I does work but requires some hardware. So the Serial bootloader...
-Don't forget to set BOOT0 to 1 (and keep BOOT1 to 0) with the appropriate jumper on the board. Then, power or or reset the Board (with the onboard switch) and flash you binary =)

-Using Parser : Raw BINARY
-Serial Config: 57600 8E1
-Version      : 0x22
-Option 1     : 0x00
-Option 2     : 0x00
-Device ID    : 0x0410 (Medium-density)
-- RAM        : 20KiB  (512b reserved by bootloader)
-- Flash      : 128KiB (sector size: 4x1024)
-- Option RAM : 16b
-- System RAM : 2KiB
-Wrote and verified address 0x08001e6c (100.00%) Done.
-Starting execution at address 0x08000000... done.</code>
-It should start right away. If you're using the USB port in your code, you will probably have to unplug and replug the board from your USB port (or else it won't enumerate...).
-This method is better, since it only requires a USB-Serial adapter. But
