-========
-Find eagle schematics at

-The board can be used for F1/L1/F2 and F4 with some changed parts,
-see the datasheet and hints in the schematic
-
-JTAG: Reuse the JTAG Connector, unconnect JTAG Tap and reuse JTAG pins
-in inverse direction.
-Forced boot request: Connect Jumper Wire X11-34/X11-40 to pull PC15
-to ground
-System Bootloader: Jumper Boot0 to '1'
-
-Led: PB2 (Boot1)

-Application start address:
-=========================
-
-Use 0x8010000
-- lower 3 16 k pages may be used for parameter storage
