Hardware
|
||||
========
|
||||
Find eagle schematics at
|
||||
https://github.com/UweBonnes/wiki_fuer_alex/tree/master/layout
|
||||
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
|
||||
- Erasing a single 64 k Page is faster then erasing 2 16 k Pages
|
||||
eventual the 64 k page
