Modified MYSBootloader OTA Size/address problem
snova last edited by
I have followed the OTA guide on the main website and it works flawlessly on many 328p.
To do so, I have downloaded MYSController and the zip file contains :
- Firmware folder
- Bootloader folder :
I have read board.txt and added the board to ARDUINO IDE as they mentioned. I burnt the bootloader and it works.
Now, It i want to change anything in the bootloader( like the NRF channel, Power, data rate, or even a line of code) i would have to rebuild the bootloader with the MYSBootloader github
I made sure that their make has the correct paths for arv-gcc and so with a shell prompt i launched a "make"
It outputs this :
$ make rm *.o rm *.elf rm *.hex "C:/WinAVR-20100110/bin/avr-gcc" -I"C:/WinAVR-20100110/avr/include/avr/" -funsigned-char -funsigned-bitfields -DF_CPU=16000000L -DBAUD_RATE=115200 -Os -ffunction-sections -fdata-sections -fpack-struct -fshort-enums -mrelax -Wall -Wextra -Wundef -pedantic -mmcu=atmega328p -c -std=gnu99 -MD -MP -MF "MYSBootloader.d" -MT"MYSBootloader.d" -MT"MYSBootloader.o" MYSBootloader.c -o MYSBootloader.o In file included from Core.h:40, from MYSBootloader.c:81: HW.h:51:4: warning: #warning is a GCC extension HW.h:51:4: warning: #warning BAUD_RATE error greater than 2% In file included from Core.h:42, from MYSBootloader.c:81: MyMessage.h:260: warning: expected [error|warning|ignored] after '#pragma GCC diagnostic' MyMessage.h:261: warning: unknown option after '#pragma GCC diagnostic' kind MyMessage.h:297: warning: ISO C doesn't support unnamed structs/unions MyMessage.h:300: warning: expected [error|warning|ignored] after '#pragma GCC diagnostic' "C:/WinAVR-20100110/bin/avr-gcc" -nostartfiles -Wl,-s -Wl,-static -Wl,-Map=".map" -Wl,--start-group -Wl,--end-group -Wl,--gc-sections -mrelax -Wl,-section-start=.text=0x7800 -mmcu=atmega328p -o MYSBootloader.elf MYSBootloader.o -lm "C:/WinAVR-20100110/bin/avr-objcopy" -O ihex -R .eeprom MYSBootloader.elf MYSBootloader.hex "C:/WinAVR-20100110/bin/avr-size" MYSBootloader.elf text data bss dec hex filename 2360 6 71 2437 985 MYSBootloader.elf
A few warning because of GCC diag ,but no error and i have a MYSBootloader.hex file ready
All i have to do is to replace the file contained in my
and from the IDE, using a aspUSB, BURN IT !
The problem is here : i get this error
avrdude: reading input file "C:\Program Files (x86)\Arduino\hardware\arduino\avr/bootloaders/MySensors/MYSBootloaderV13pre.hex" avrdude: ERROR: address 0x8010 out of range at line 129 of C:\Program Files (x86)\Arduino\hardware\arduino\avr/bootloaders/MySensors/MYSBootloaderV13pre.hex Error while burning bootloader. avrdude: read from file 'C:\Program Files (x86)\Arduino\hardware\arduino\avr/bootloaders/MySensors/MYSBootloaderV13pre.hex' failed
the 0x8010 address is 32784 in DEC which is more than the maximum allow by this line in board.txt and more than the physical flash memory possible on ATmega328p (32768 bytes)
The question is Why is it outputting a code that has these addresses in its HEX file ?
How can this be possibly solved ?
Thank you .

Install ATmel Studio and edit Make file PATH for WIN10.
Great work @, thanks for reporting back!
