How to compile bootlaoders? #120

Closed harryberlin closed 5 years ago

Hello I did a mod for optiboot_flash.c After this, i tried to compile on debian stretch with this command make -e TOOLROOT=/home/pi/arduino-nightly/hardware/tools/avr But the script fails:

Build 1 of 6318 Target 1 of 78 Sub build 0 of 81 make atmega8 AVR_FREQ=24000000L BAUD_RATE=1000000 LED=B5 LED_START_FLASHES=2 UART=0 Using avr-gcc 7.3.0

your bootloader doesn't fit into memory limit "section .text' is not within region text"

MCUdude commented 5 years ago

You can increase the size by adding SUPPORT_ EEPROM=1 to the makefile command

or BIGBOOT=1 ?

got it working with this command: make atmega2560 AVR_FREQ=16000000L BAUD_RATE=115200 LED=B7 LED_START_FLASHES=2 UART=0 SUPPORT_EEPROM=1
