*
|
||||||
|
* AVRPROG compatible boot-loader
|
||||||
|
* Version : 0.2 (24. March 2004)
|
||||||
|
* Compiler : avr-gcc 3.3.1 / avr-libc 1.0
|
||||||
|
* size : ca. 610 word ( larger than 512 words :-( )
|
||||||
|
* by : Martin Thomas, Kaiserslautern, Germany
|
||||||
|
* eversmith@heizung-thomas.de
|
||||||
|
*
|
||||||
|
* based on the Butterfly Bootloader-Code
|
||||||
|
* Copyright (C) 1996-1998 Atmel Corporation
|
||||||
|
* Author(s) : BBrandal, PKastnes, ARodland, LHM
|
||||||
|
*
|
||||||
|
* The orignal code has been made available by ATMEL together with the
|
||||||
|
* Butterfly application code. Since ATMEL.NO had no problem with
|
||||||
|
* the application gcc-port they hopefully will not have any concerns about
|
||||||
|
* publishing this port. Make sure to keep the copyright notice in derived
|
||||||
|
* work to avoid trouble.
|
||||||
|
****************************************************************************
|
||||||
|
*
|
||||||
|
* Many functions used by "AVRPROG" (fuses) have been disabled by ATMEL in
|
||||||
|
* the original source code of the Butterfly Boot-loader not by me.
|
||||||
|
* Please 'diff' against the original source to see everything that has been
|
||||||
|
* changed for the gcc port.
|
||||||
|
*
|
||||||
|
* The boot interrupt vector is included (this bootloader is completly in
|
||||||
|
* ".text" section). If you need this space for further functions you have to
|
||||||
|
* add a separate section for the bootloader-functions and add an attribute
|
||||||
|
* for this section to _all_ function prototypes of functions in the loader.
|
||||||
|
* With this the interrupt vector will be placed at .0000 and the bootloader
|
||||||
|
* code (without interrupt vector) at the adress you define in the linker
|
||||||
|
* options for the newly created section. See the avr-libc FAQ and the avr-
|
||||||
|
* libc's avr/boot.h documentation for further details.
|
||||||
|
*
|
||||||
|
* For this bootloader a Boot-Size of at least 0x4C4 (1220) bytes =
|
||||||
|
* 610 words is needed. Sorry, so far efforts to shrink to 512 words failed.
|
||||||
|
* See the makefile for information how to adopt the linker-settings to
|
||||||
|
* the selected Boot Size (_Bxxx below)

ATMEL AVR UART Bootloader for AVR-GCC/avr-libc
|
||||||
|
based on the AVR Butterfly bootloader code
|
||||||
|
|
||||||
|
by Martin Thomas, Kaiserslautern, Germany
|
||||||
|
mthomas@rhrk.uni-kl.de
|
||||||
|
eversmith@heizung-thomas.de
|
||||||
|
|
||||||
|
This is an adapted version which has been tested
|
||||||
|
with the ATmega16 but should work with the ATmega8,
|
||||||
|
ATmega169 and ATmega32. The bootloader uses block/
|
||||||
|
page write and is fast.
|
||||||
|
|
||||||
|
======================================================
|
||||||
|
|
||||||
|
|
||||||
|
24. Mar 2004 - Version 0.2
|
||||||
|
|
||||||
|
During the development of a data-logger application
|
||||||
|
with the AVR-Butterfly there was a need to make
|
||||||
|
some changes in the bootloader. The same problem
|
||||||
|
again: no IAR compiler. The same way to solve the
|
||||||
|
problem: a port of the code to avr-gcc/avr-libc.
|
||||||
|
So this code is based on the ATMEL Butterfly
|
||||||
|
bootloader source code Rev 0.2 for IAR.
|
||||||
|
|
||||||
|
The bootloader-port for the Butterfly which mimics
|
||||||
|
the complete functionality of the original
|
||||||
|
BF-bootloader is availabe at:
|
||||||
|
www.siwawi.arubi.uni-kl.de/avr_projects
|
||||||
|
|
||||||
|
Atmel used a separate "lib" written in "pure"
|
||||||
|
assembly to access the low-level functions
|
||||||
|
for flash and eeprom read/write. Well, so far I
|
||||||
|
don't know how to use "mixed language sources"
|
||||||
|
with the avr-gcc toolchain, so the low-level
|
||||||
|
routines have been implemented as inline assembler.
|
||||||
|
The avr-libc boot.h module written by Eric
|
||||||
|
Weddington served as a template Three of the four
|
||||||
|
low-level routines found in lowlevel.c come from
|
||||||
|
boot.h with minimal changes. The read routine has
|
||||||
|
been developed based on the ATMEL assembler code.
|
||||||
|
|
||||||
|
Ignore the fuse and lock-bit readout. Read and Set is
|
||||||
|
not enabled (TODO).
|
||||||
|
|
||||||
|
|
||||||
|
--------------- Installation -----------------
|
||||||
|
|
||||||
|
- Change the MCU type in the makefile (so far
|
||||||
|
ATmega16 has been tested, ATmega169, ATmega8
|
||||||
|
and ATmega32 should be o.k. too.
|
||||||
|
|
||||||
|
- Change the boot(loader)-size in main.c, this
|
||||||
|
bootloader is larger than 512 words (1024 bytes),
|
||||||
|
so select at least _B1024!
|
||||||
|
|
||||||
|
- Change the XTAL in main.c to the clock-frequency
|
||||||
|
of your board (keep BAUDRATE at 19200). See
|
||||||
|
the datasheet for frequencies with minimum
|
||||||
|
error at 19200bps and select Crystal/Oscillator
|
||||||
|
to get minimum errors.
|
||||||
|
|
||||||
|
- Change the start-condition in main.c. Default
|
||||||
|
is: enter bootloader if Pin A7 is connected to
|
||||||
|
GND during reset/startup
|
||||||
|
|
||||||
|
- Edit the value MT_BOOTLOADER_ADDRESS in the
|
||||||
|
makefile according to the selected bootloader
|
||||||
|
size. Keep in mind that this value has to be
|
||||||
|
given in bytes (not words) in the linker options.
|
||||||
|
|
||||||
|
i.e. ATMega16, boot-size 1024 words, see
|
||||||
|
datasheet and find "Boot Reset Adress" for
|
||||||
|
"Boot Size" 1024 words is 1C00. 1C00 is given
|
||||||
|
in words, so set MT_BOOTLOADER_ADDRESS to
|
||||||
|
3800 (=2*1C00)
|
||||||
|
|
||||||
|
- Please use at least avr-gcc 3.3.1/avr-libc 1.0
|
||||||
|
or WINAVR Sept. 2003 or later to compile and link
|
||||||
|
the bootloader.
|
||||||
|
|
||||||
|
- upload the hex-File to the AVR (STK500, STK200, SP12
|
||||||
|
etc.)
|
||||||
|
|
||||||
|
- program the "Boot Flash section size" (BOOTSZ fuses)
|
||||||
|
according to the boot-size selected in main.c
|
||||||
|
i.e. BOOTSZ=00 for boot-size 1024 words on ATmega16
|
||||||
|
|
||||||
|
- enable the BOOT Reset Vector (BOOTTRST=0)
|
||||||
|
|
||||||
|
- Set the lock bits to protect the bootloader from
|
||||||
|
SPM-writes (Boot Loader Protection Mode 2 in STK500-
|
||||||
|
plugin)
|
||||||
|
|
||||||
|
- Connect the AVR UART Pins via level-shifter/inverter
|
||||||
|
(i.e. MAX232) to you PCs Com-Port.
|
||||||
|
|
||||||
|
- Reset the AVR while fullfilling the bootloader start-
|
||||||
|
condition. Which means connect PA7 to GND in the default
|
||||||
|
config during reste/power-cycle. Keep the connection
|
||||||
|
or hold the key down until you see the AVRPROG dialog!
|
||||||
|
|
||||||
|
- Start AVRPROG (AVRStuido/Tools or stand-alone) -
|
||||||
|
keep PA7 grounded!
|
||||||
|
|
||||||
|
- AVRPROG will detect the bootloader, you may release
|
||||||
|
PA7 now
|
||||||
|
|
||||||
|
- see AVRStuido online-help for more information how
|
||||||
|
to use AVRPROG
|
||||||
|
|
||||||
|
- make sure to EXIT from AVRPROG (button) to start
|
||||||
|
your main-application (or toogle power/reset)
|
||||||
|
|
||||||
|
good luck, feedback welcome.
