** Addtional code and improvements contributed **
|
||||||
|
** by Uwe Bonnes, Bjoern Riemer and Olaf Rempel. **
|
||||||
|
|
||||||
|
Eearly versions of this bootloader-code have been
|
||||||
|
based on the AVR Butterfly bootloader-source REV02
|
||||||
|
which has been available from atmel.com.
|
||||||
|
|
||||||

======================================================
|
||||||

|
|
||||||
|
Programming-Software (on the "PC-Side"):
|
||||||
|
|
||||||
|
* AVRProg (included in AVRStudio) available at www.atmel.com.
|
||||||
|
MS-Windows only. AVRProg can be used as stand-alone application.
|
||||||
|
(avrprog.exe)
|
||||||
|
|
||||||
|
* avrdude available at http://savannah.nongnu.org/projects/avrdude/
|
||||||
|
"Multiplattform"
|
||||||
|
|
||||||
|
* Installation instructions at the end of this file.
|
||||||
|
|
||||||
|
|
||||||
|
3. Dec. 2008 - Version 0.85
|
||||||
|
|
||||||
|
* disable U2X before jump to app as suggested be Alexander Döller
|
||||||
|
* moved UBRR-macros to main.c and changed them. Inspired by code from avr-libc setbaud.
|
||||||
|
(macros which are commented out (//) are from Pavel Fertser)
|
||||||
|
|
||||||
|
6. Nov. 2008 - Version 0.84
|
||||||
|
|
||||||
|
* Added definitions for ATmega64 provided by Pavel Fertser - Thanks.
|
||||||
|
|
||||||
|
12. Apr. 2008 - Version 0.83
|
||||||
|
|
||||||
|
* Added definitions for ATmega644P and ATmega324P
|
||||||
|
* Tested with ATmega324P, gcc 4.2.2, avr-libc 1.4.6
|
||||||
|
* Added testapp to verify "exit bootloader" with
|
||||||
|
watchdog (n.b.: watchdog-disable called early in testapp)
|
||||||
|
|
||||||
|
27. Jan. 2007 - Version 0.82
|
||||||
|
|
||||||
|
* Added definitions for ATmega644.
|
||||||
|
* Using avr-lib's eeprom-functions (old "direct-access"-code
|
||||||
|
has not been compatible with ATmega644).
|
||||||
|
* Watchdog-disable at startup (configurable): avoids problems with
|
||||||
|
repeated login to bootloader. Not needed if the bootloader is
|
||||||
|
never re-entered again between an "exit programming" and
|
||||||
|
a system-reset/power-toogle.
|
||||||
|
* Additional watchdog disable-function for ATmega644.
|
||||||
|
* Made watchdog-enable time at exit-programming a configuration-value
|
||||||
|
(define).
|
||||||
|
* Bootloader read-protection: if enabled the bootloader fakes
|
||||||
|
an empty boot-section (configurable by define)
|
||||||
|
Since more of the avr-libc functions's are used this version
|
||||||
|
should be more portable for other AVRs but the size of the
|
||||||
|
binary increases a little bit.
|
||||||
|
Make sure to disable the watchdog early in the user-application
|
||||||
|
esp. when using a "modern" AVR (i.e. ATmega48/88/168/644/324P/644P).
|
||||||
|
|
||||||
|
3. Dec. 2006 - Version 0.81
|
||||||
|
|
||||||
|
* Added definitions for ATmega162.
|
||||||
|
* Fixed init for double-speed (bitmask). Thanks to Bernhard Roth
|
||||||
|
|
||||||
|
28. May 2006 - Version 0.8beta3
|
||||||
|
|
||||||
|
* Supports discarding of interrupt-vectors which saves some space
|
||||||
|
if no interrupts are needed in the bootloader. Added option
|
||||||
|
in makefile to enable this feature, modified LDFLAGS,
|
||||||
|
additional code in main.c for a pseudo default_interrupt ISR.
|
||||||
|
The modified linker-scripts have been contributed by
|
||||||
|
Olaf Rempel (basicly just the .vector-section is not linked).
|
||||||
|
* Reverted the order of signatur-byte-numbers in part-
|
||||||
|
configurations to the usual order in the datasheet,
|
||||||
|
also reverted in main.c for sending the signature.
|
||||||
|
* Definitions for lock/fuse-readout.
|
||||||
|
* Updated installation-instruction at the end of this file.
|
||||||
|
* Added DEVTYPE_ISP/DEVTYPE_BOOT to part-configurations,
|
||||||
|
added configuration-option for this in main.c.
|
||||||
|
* A remark about the DEVTYPE: Usualy there are two
|
||||||
|
Part-Codes/Device-Codes. One is for ISP: AVRProg shows
|
||||||
|
the type of the AVR. The other code is for bootloading:
|
||||||
|
AVRprog shows the type plus "BOOT". When a boot-device-code
|
||||||
|
gets detected by AVRprog it "knows" how do handle the
|
||||||
|
limited functionality of bootloaders. (When receiving the
|
||||||
|
ISP-code AVRProg expects an AVR910-type programmer.)
|
||||||
|
The offset between the codes is usualy 0x01 where the
|
||||||
|
ISP-code is the smaller value, i.e. ATmega32 ISP-code
|
||||||
|
is 0x72->"ATmega32" and boot-code is 0x73->"ATmega32 BOOT".
|
||||||
|
When using avrdude the bootloader's device-code must match
|
||||||
|
the device-code in the avrdude.conf. Check the avrdude-
|
||||||
|
code to see if both codes (AVR910 and AVR109) are supported.
|
||||||
|
-- I have got some e-mails from users which have been
|
||||||
|
confused by this. Hopefully this explanation is good enough.
|
||||||
|
* This bootloader lets the watchdog do a reset when the
|
||||||
|
user selects "Exit programmer" (i.e. in AVRProg) after an
|
||||||
|
update. Make sure to disable or reset the watchdog early in
|
||||||
|
your application.
|
||||||
|
|
||||||
|
27. May 2006 - Version 0.8beta2
|
||||||
|
|
||||||
|
* More very well done improvements contributed by Olaf Rempel.
|
||||||
|
* Olaf Rempel also modified the STARTUP_WAIT method.
|
||||||
|
|
||||||
|
21. May 2006 - Version 0.8beta
|
||||||
|
|
||||||
|
* Version contributed by Olaf Rempel. He has done a lot of modifications.
|
||||||
|
-> "cleaner code", smaller binaries.
|
||||||
|
|
||||||
|
09. Feb. 2006 - Version 0.75
|
||||||
|
|
||||||
|
* additional STARTUP_WAIT support contributed by Bjoern Riemer
|
||||||
|
|
||||||
|
18. Aug. 2005 - Version 0.74
|
||||||
|
|
||||||
|
* AT90CAN128 support contributed by Uwe Bonnes
|
||||||
|
* Makefile modifications contributed by Uwe Bonnes
|
||||||
|
|
||||||
|
23. Feb. 2005 - Version 0.7
|
||||||
|
|
||||||
|
* (Version 0.6 has never been available on the web-page)
|
||||||
|
* ATmega128 support
|
||||||
|
* code cleanup
|
||||||
|
* This version has been tested with ATmega8, ATmega32 and
|
||||||
|
ATmega128
|
||||||
|
|
||||||
|
7. Apr. 2004 - Version 0.5
|
||||||
|
|
||||||
|
* added different startup-methods
|
||||||
|
* compatible with ATmega8 now
|
||||||
|
* included makefile adapted to ATmega8 now
|
||||||
|
(ATmega16 options still available)
|
||||||
|
* fixed jump to application which did not work
|
||||||
|
reliably before
|
||||||
|
* tested with ATmega8
|
||||||
|
* minimal options and startup-code result in
|
||||||
|
bootloader-size < 512 words
|
||||||
|
|
||||||
|
6. Apr. 2004 - Version 0.4
|
||||||
|
|
||||||
|
* Buffered read of chars from UART during programming
|
||||||
|
since eeprom-write is too slow for unbuffered
|
||||||
|
operation. So EEPROM-upload does work now.
|
||||||
|
* Added BOOTICE-mode to flash JTAGICE-compatible
|
||||||
|
hardware (ATmega16@7,3Mhz) (if you know about BOOTICE,
|
||||||
|
you may unterstand why this has been added, if not
|
||||||
|
just keep the option disabled)
|
||||||
|
* small changes in (my)boot.h (lock-bit-mask) found
|
||||||
|
out during the development of the STK-500-compatible
|
||||||
|
bootloader. But setting lock-bits still does not
|
||||||
|
work with this bootloader.
|
||||||
|
* read of the low-fuse byte works (high byte still TODO)
|
||||||
|
* read of the lock-byte works (write still TODO)
|
||||||
|
|
||||||
|
27. Mar 2004 - Version 0.3
|
||||||
|
|
||||||
|
Felt that as much functions from avr-libc's boot.h
|
||||||
|
as possible should be used without modifications.
|
||||||
|
Latest CVS-version of boot.h is included.
|
||||||
|
Only the read-routine is still "self-made" based
|
||||||
|
on ATMELs assembler-code.
|
||||||
|
EEPROM write on Mega16 does not work (and did not
|
||||||
|
work with V0.2 too). May be caused by my old Mega16
|
||||||
|
chip. Needs testing. Flash read/write and EEPROM
|
||||||
|
read works. Still only tested with ATmega16.
|
||||||
|
This version may not work with the ATmega169 any
|
||||||
|
more.
|
||||||
|
|
||||||
|
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 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.
|
||||||
|
|
||||||
|
- Change the boot(loader)-size in Makefile. The needed
|
||||||
|
space depends on the features selected in main.c
|
||||||
|
|
||||||
|
- Set baudrate in main.c, a doublespeed configuration-option
|
||||||
|
is available too.
|
||||||
|
|
||||||
|
- Change the F_CPU in main.c to the clock-frequency
|
||||||
|
of your board. See the datasheet for frequencies
|
||||||
|
with minimum error at the selected baudrate.
|
||||||
|
|
||||||
|
- Select the start-condition in main.c.
|
||||||
|
|
||||||
|
- Please use at least avr-gcc 3.3.1/avr-libc 1.0
|
||||||
|
or WINAVR Sept. 2003 or later to compile and link
|
||||||
|
this bootloader.
|
||||||
|
|
||||||
|
- Upload the hex-File to the AVR (STK500, STK200, SP12
|
||||||
|
evertool, AVR910 etc.)
|
||||||
|
|
||||||
|
- Program the "Boot Flash section size" (BOOTSZ fuses)
|
||||||
|
according to the boot-size selected in the makefile
|
||||||
|
i.e. BOOTSZ=00 for boot-size 1024 words (2048 bytes)
|
||||||
|
on ATmega16
|
||||||
|
|
||||||
|
- enable the BOOT Reset Vector fuse (BOOTRST=0)
|
||||||
|
|
||||||
|
- Set the lock bits to protect the bootloader from
|
||||||
|
SPM-writes (Boot Loader Protection Mode 2 in STK500-
|
||||||
|
plugin) so that it can not overwrite itself.
|
||||||
|
|
||||||
|
- Connect the AVR UART Pins via level-shifter/inverter
|
||||||
|
(i.e. MAX232) to your PCs COM-Port.
|
||||||
|
|
||||||
|
- Reset the AVR while fullfilling the bootloader start-
|
||||||
|
condition. (Default: selected pin connected to GND).
|
||||||
|
The condition must be "true" until you see the
|
||||||
|
AVRPROG dialog or avrdude connects.
|
||||||
|
|
||||||
|
- Start AVRPROG (AVRStudio/Tools or stand-alone avrprog.exe)
|
||||||
|
AVRDUDE is supported too, check it's manual
|
||||||
|
for command-line options. Read the text above for
|
||||||
|
information about Device-Types and AVRDUDE
|
||||||
|
|
||||||
|
- AVRPROG or AVRDUDE should detect the bootloader.
|
||||||
|
|
||||||
|
- see AVRStudio's 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.
|
||||||
|
|
||||||
|
|
||||||
|
Feedback welcome, Good luck.
