File: $Id: stk500boot.c,v 1.11 2006/06/25 12:39:17 peter Exp $
|
|
Compiler: avr-gcc 3.4.5 or 4.1 / avr-libc 1.4.3
|
|
Hardware: All AVRs with bootloader support, tested with ATmega8
|
|
License: GNU General Public License

Modified: Worapoht Kornkaewwattanakul <dev@avride.com> http://www.avride.com
|
|
Date: 17 October 2007
|
|
Update: 1st, 29 Dec 2007 : Enable CMD_SPI_MULTI but ignore unused command by return 0x00 byte response..
|
|
Compiler: WINAVR20060421
|
|
Description: add timeout feature like previous Wiring bootloader
|
|
|
|
DESCRIPTION:
|
|
This program allows an AVR with bootloader capabilities to
|
|
read/write its own Flash/EEprom. To enter Programming mode
|
|
an input pin is checked. If this pin is pulled low, programming mode
|
|
is entered. If not, normal execution is done from $0000
|
|
"reset" vector in Application area.
|
|
Size fits into a 1024 word bootloader section
|
|
when compiled with avr-gcc 4.1
|
|
(direct replace on Wiring Board without fuse setting changed)
|
|
|
|
USAGE:
|
|
- Set AVR MCU type and clock-frequency (F_CPU) in the Makefile.
|
|
- Set baud rate below (AVRISP only works with 115200 bps)
|
|
- compile/link the bootloader with the supplied Makefile
|
|
- program the "Boot Flash section size" (BOOTSZ fuses),
|
|
for boot-size 1024 words: program BOOTSZ01
|
|
- enable the BOOT Reset Vector (program BOOTRST)
|
|
- Upload the hex file to the AVR using any ISP programmer
|
|
- Program Boot Lock Mode 3 (program BootLock 11 and BootLock 12 lock bits) // (leave them)
|
|
- Reset your AVR while keeping PROG_PIN pulled low // (for enter bootloader by switch)
|
|
- Start AVRISP Programmer (AVRStudio/Tools/Program AVR)
|
|
- AVRISP will detect the bootloader
|
|
- Program your application FLASH file and optional EEPROM file using AVRISP
|
|
|
|
Note:
|
|
Erasing the device without flashing, through AVRISP GUI button "Erase Device"
|
|
is not implemented, due to AVRStudio limitations.
|
|
Flash is always erased before programming.
|
|
|
|
AVRdude:
|
|
Please uncomment #define REMOVE_CMD_SPI_MULTI when using AVRdude.
|
|
Comment #define REMOVE_PROGRAM_LOCK_BIT_SUPPORT to reduce code size
|
|
Read Fuse Bits and Read/Write Lock Bits is not supported
|
|
|
|
NOTES:
|
|
Based on Atmel Application Note AVR109 - Self-programming
|
|
Based on Atmel Application Note AVR068 - STK500v2 Protocol

//* Jul 7, 2010 <MLS> Working on mega2560. No Auto-restart
|
|
//* Jul 7, 2010 <MLS> Switched to 8K bytes (4K words) so that we have room for the monitor
|
|
//* Jul 8, 2010 <MLS> Found older version of source that had auto restart, put that code back in
|
|
//* Jul 8, 2010 <MLS> Adding monitor code
|
|

|
//* Reported by mark.stubbs, Mar 14, 2011
|
|
//* The STK500V2 bootloader is comparing the seqNum to 1 or the current sequence
|
|
//* (IE: Requiring the sequence to be 1 or match seqNum before continuing).
|
|
//* The correct behavior is for the STK500V2 to accept the PC's sequence number, and echo it back for the reply message.
