как загрузить bootloader в нужное место в VMLAB

Сообщение moldov » 26 янв 2012, 16:24

Всем привет.
Имею Atmega32L, VMLAB + WinAVR  для отладки
Пишу бутлоадер для своего проекта.
Как изменить Program Counter на нужный адрес нашел. Прописал в файле проекта VMLAB
Код: Выделить всёРазвернуть

При запуске счетчик устанавливается на начало бутолдыря

А вот как указать, что надо во флэш записать мой лодер по требуемому адресу я не знаю. Он записывается в 0x0000  по умолчанию

Нарыл что надо прописать флаги
Код: Выделить всёРазвернуть
 LDFLAGS = -Wl,--section-start=.text=0x03800 

Прописал, но не работает. Пишет ""Program counter at unprogrammed flash location

Вот makefile

# Automatically generated by VMLAB from "<VMLAB>\bin\templa33.mak" template file.
# Added default dependency ELF->COF (AMTools).
# WinAVR Sample makefile written by Eric B. Weddington, Jörg Wunsch, et al.
# Released to the Public Domain
# Please read the make user manual!
# Additional material for this makefile was submitted by:
#  Tim Henigan
#  Peter Fleury
#  Reiner Patommel
#  Sander Pool
#  Frederik Rouleau
#  Markus Pfaff
# On command line:
# make all = Make software.
# make clean = Clean out built project files.
# make coff = Convert ELF to AVR COFF (for use with AVR Studio 3.x or VMLAB).
# make extcoff = Convert ELF to AVR Extended COFF (for use with AVR Studio
#                4.07 or greater).
# make program = Download the hex file to the device, using avrdude.  Please
#                customize the avrdude settings below first!
# make filename.s = Just compile filename.c into the assembler code only
# To rebuild project do "make clean" then "make all".

# ---------------------------------------------------------------------------
# Define directories, if needed.
DIRLIB = $(DIRAVR)/avr/lib

# MCU name
MCU = atmega32

# Output format. (can be srec, ihex, binary)

# Target file name (without extension).
TARGET = uboot

# Optimization level, can be [0, 1, 2, 3, s]. 0 turns off optimization.
# (Note: 3 is not always the best optimization level. See avr-libc FAQ.)
OPT = s

# List C source files here. (C dependencies are automatically generated.)
SRC = uboot.c uart.c

# If there is more than one source file, append them above, or modify and
# uncomment the following:
#SRC += foo.c bar.c

# You can also wrap lines by appending a backslash to the end of the line:
#SRC += baz.c \

# List Assembler source files here.
# Make them always end in a capital .S.  Files ending in a lowercase .s
# will not be considered source files but generated files (assembler
# output from the compiler), and will be deleted upon "make clean"!
# Even though the DOS/Win* filesystem matches both .s and .S the same,
# it will preserve the spelling of the filenames, and gcc itself does
# care about how the name is spelled on its command-line.

# List any extra directories to look for include files here.
#     Each directory must be seperated by a space.

# Optional compiler flags.
#  -g:        generate debugging information (for GDB, or for COFF conversion)

#  -Wa,...:   tell GCC to pass this to the assembler.

#  -gstabs:   have the assembler create line number information; note that
#             for use in COFF files, additional information about filenames

Не помогает.

Re: как загрузить bootloader в нужное место в VMLAB

Сообщение moldov » 27 янв 2012, 08:45

Все сам разобрался!

Во первых WinAVR не чистит файлы перед каждым Make. И поэтому я вручную стер все файлы кроме файлов makefile, *.prj, *.c, *.h
Прописал в Makefile опцию линкера. ВНИМАНИЕ!!! надо указывать BYTE адрес 0x7000 вместо 0x3800 так как WinAVR использует Byte адресацию а Atmega Word - адресацию.

Код: Выделить всёРазвернуть
LDFLAGS +=   -Wl,--section-start=.text=0x7000

Теперь вот ищу как прерывания перенаправить куда надо.
