Date: 17 October 2007
|

Update: 1st, 29 Dec 2007 : Enable CMD_SPI_MULTI but ignore unused command by return 0x00 byte response..
|
13 |
Compiler: WINAVR20060421
|
14 |
Description: add timeout feature like previous Wiring bootloader
|
15 |
|
16 |
DESCRIPTION:
|
17 |
This program allows an AVR with bootloader capabilities to
|
18 |
read/write its own Flash/EEprom. To enter Programming mode
|
19 |
an input pin is checked. If this pin is pulled low, programming mode
|
20 |
is entered. If not, normal execution is done from $0000
|
21 |
"reset" vector in Application area.
|
22 |
Size fits into a 1024 word bootloader section
|
23 |
when compiled with avr-gcc 4.1
|
24 |
(direct replace on Wiring Board without fuse setting changed)
|
25 |
|
26 |
USAGE:
|
27 |
- Set AVR MCU type and clock-frequency (F_CPU) in the Makefile.
|
28 |
- Set baud rate below (AVRISP only works with 115200 bps)
|
29 |
- compile/link the bootloader with the supplied Makefile
|
30 |
- program the "Boot Flash section size" (BOOTSZ fuses),
|
31 |
for boot-size 1024 words: program BOOTSZ01
|
32 |
- enable the BOOT Reset Vector (program BOOTRST)
|
33 |
- Upload the hex file to the AVR using any ISP programmer
|
34 |
- Program Boot Lock Mode 3 (program BootLock 11 and BootLock 12 lock bits) // (leave them)
|
35 |
- Reset your AVR while keeping PROG_PIN pulled low // (for enter bootloader by switch)
|
36 |
- Start AVRISP Programmer (AVRStudio/Tools/Program AVR)
|
37 |
- AVRISP will detect the bootloader
|
38 |
- Program your application FLASH file and optional EEPROM file using AVRISP
|
39 |
|
40 |
Note:
|
41 |
Erasing the device without flashing, through AVRISP GUI button "Erase Device"
|
42 |
is not implemented, due to AVRStudio limitations.
|
43 |
Flash is always erased before programming.
|
44 |
|
45 |
AVRdude:
|
46 |
Please uncomment #define REMOVE_CMD_SPI_MULTI when using AVRdude.
|
47 |
Comment #define REMOVE_PROGRAM_LOCK_BIT_SUPPORT to reduce code size
|
48 |
Read Fuse Bits and Read/Write Lock Bits is not supported
|
49 |
