I need to upload code on atmega328 wihout bootloader
https://github.com/EasyOne2030/test but see Sketch uses 33218 bytes (102%) of program storage space. Maximum is 32256 bytes ?

  • If you eliminate the use of PPT_bits, you would have sufficient memory already. Alternative, you had 4 images representing RSSI, 5 images representing battery, and 3 images representing volume, if you eliminate one each, you would have sufficient memory also. If you insists to have all of them, then change the MCU to have bigger flash.

In the case where the size of the program (sketch) has become too large for the available program storage space (flash memory), there are a number of options. Note that this is not the same case as exceeding the amount of dynamic memory (RAM) which requires a different set of solutions.

_1. Microcontroller (MCU) upgrade.

This can be a solution. The closer the architecture of the new MCU matches that that of the old MCU the easier this is likely to be. However, this approach can become complex, even when using a different MCU in the same series as the original, if low level configuration of (and access to) hardware peripherals such as timers, ports etc. has been used. Be aware that any libraries used may not be compatible with the new MCU so testing is important. In the worst case, there may be no supporting Arduino core available for the new MCU. Major incompatibilities can be tested with a simple compilation of a sketch for the new target MCU and this does not even require the new MCU to be present.

In the specific case of the ATmega328P, this is already the highest specified MCU in its series so a new MCU is required to increase resources such as Flash memory, RAM etc. An ATMega1284 may be a possible replacement within the AVR range. Also to consider is an ATmega4809 (newer megaAVR range) based board such as the Nano Every but here there are more significant architectural differences

_2. Optimising the use of flash memory.

_2.1 Bootloader.

Sometimes, changing the bootloader for a smaller one can help. For example, with some Arduino Nanos, this can free 1.5KB of flash memory by changing to the same bootloader which is used on the Arduino Uno (Optiboot). Dropping the bootloader altogether and using an ISP programmer (or an Arduino configured as one) to program the MCU can also save flash memory. Here it is important to select an Arduino core which supports a "No Bootloader" option to achieve the maximum benefits from this approach. The core "Minicore" https://github.com/MCUdude/MiniCore is such an example. Important to note is the the Arduino IDE (base 1.8.19) has a special upload procedure when using a programmer (Sketch--> Upload using programmer). Note also that the target (AVR) MCU must have the fuses correctly set for "no bootloader" operation. That is the fuse BOOTRST must be unset. This is achieved by using the "burn bootloader" option supplied by the core. Despite its (inappropriate) name this has the effect of setting the fuses. Alternatively, the fuses can be set manually using the AVRDUDE command line.

_2.2 General.

The compiler is quite good at optimising code however, it is important to be aware that the use of some program features can have a one time penalty when used. Examples are the String class, sprintf(), floating point handling etc. which force a large amount of code to be added to the compiled sketch. Some libraries can consume a large amount of program memory. Graphic libraries are notorious for this because often these include large font tables etc. Here the options are limited to looking for a lighter weight library or a hacking out unused parts of an existing library.

  • @onenext Download and install "MiniCore" from the location in the answer above. The readme.md there has a "how to install" section. Once you have correctly installed this, then from the Tools menu in the Arduino IDE select: Boards -> Minicore -> 328P. Again in the Tools menu, select the Bootloader Option and choose "No Bootloader". Once your sketch is ready to upload, you connect your programmer and use the special upload function under the sketch menu "Upload using Programmer". This procedure will give you an extra 256 bytes of program memory (flash).

  • I have usbasp avr programmer and AVRDUDESS Ineed hex file to uplod this code on atmega328 but When export compiled binary i see error message ........ Sketch uses 33198 bytes (102%) of program storage space. Maximum is 32256 bytes. Global variables use 966 bytes (47%) of dynamic memory, leaving 1082 bytes for local variables. Maximum is 2048 bytes ...... You can have a look at the original project youtu.be/EPfLin7sqp4 ...

  • To recover the 512 bytes (my first comment incorrectly said 256) which is allocated to the bootloader, the recommendation is to use minicore. You do, however, also have the option of hacking a new entry into the boards.txt file of the standard Arduino core, if you prefer. See: forum.arduino.cc/t/boards-txt-definition-for-no-bootloader/…

Using Minicore to compile and load a program onto an ATmega328P without a bootloader. Screen shots and sample output.

Resources used

  1. CH340 ATmega328P Arduino Nano clone
  2. A programmer (Nano based) running the Arduino ISP sketch
  3. Minicore 2.1.3 https://github.com/MCUdude/MiniCore
  4. Arduino IDE 1.8.19
/*
   Example sketch to use all flash memory of an ATmega328P
*/

const uint8_t bigArray[30121] PROGMEM = {0} ;

void setup() {
  Serial.begin( 115200 ) ;
  Serial.println("test-01" ) ;
  byte buffer = pgm_read_byte_near(bigArray+50); // stop compiler optimising the array away
  Serial.println(buffer ) ;
  pinMode(LED_BUILTIN, OUTPUT);
}


void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
}

Select Programmer Select Programmer

Select No Bootloader Select No Bootloader

Burn Bootloader /set fuses Burn Bootloader /set fuses

Yes, even though you don't want a boot loader, you have to do this to correct the fuses (specifically, BOOTRST is unset by this procedure)
