SD Bootloader

[Jono72]

Hi zevero,

I have been working on a project and would like to be able to flash my 1284P from SD card for updates, I have loaded your avr_boot, firstly i am unable to select standard pinout as it will not compile, so i left it set as avr-developers.com, this must be different from standard as it my program although runs and loads does not run as it should (i was using the mightycore bootloader before), if i reload that, the code runs fine.
Using avr_boot, I created BIN file as instructed and tried to load it , i moved my SD card CS to pin 10 (as i thought you should not use pin 4 on the 1284P the SS pin as a CS)
However the hex file does not load, it just boots up as before with program not operating as it should, when i reload Mighty Core (standard pin), my project runs fine. am i doing something wrong or is there another library to use? i tried downloading the Mighty 1284P standard as in your option selection, i just get a boards.txt error.

here is a copy of the error if i select standard Mighty1284P

Error compiling for board ATmega1284/P.

You could try flashing my build for the 1284p?
https://github.com/JadinAndrews/avr_boot/blob/master/build/atmega1284p_cs4_16000000L_serial_fat32.hex

I managed to get serial working, the only issue is that the device signature is wrong and your flasher will think it is an ATmega 1284 non 'p'. Cable select is on pin 4, iirc, you were not supposed to use cable select on pin 10. Can't remember why or whatnot, but the above works.

i am unable to select standard pinout as it will not compile,

By default the ATmega1284P standard variant requires Mighty 1284P to be installed:
https://github.com/JChristensen/mighty-1284p/tree/v1.6.3
That is the cause of the error you got.

You can easily modify avr_boot to reference the MightyCore variant by simply changing line 384 of boards.txt from:

avr_boot_atmega1284.menu.pinout.standard.build.variant=mighty-1284p:standard

to:

avr_boot_atmega1284.menu.pinout.standard.build.variant=MightyCore:standard

Looking at the documentation I wrote now I see that I didn't explain that.

Although MightyCore is superior in every other aspect, I chose Mighty 1284P by default because it has the Sleeping Beauty variant, which MightyCore does not. Since that time I got the author of the Sleeping Beauty to provide an open source license so I am now able to add native support for that variant to avr_boot, which I planned to do for the next release. However, there has not been any development work merged to the avr_boot bootloader code since the last release so no reason for a new one.

i moved my SD card CS to pin 10 (as i thought you should not use pin 4 on the 1284P the SS pin as a CS)

After you change the Tools > SD CS Pin option you need to to a Tools > Burn Bootloader again. Also, make sure you have the correct pin on the ATmega1284P connected. For the avr_developers variant Arduino pin 10 is mapped to PD2.

Awesome, thanks guys for the support, will give that a try :)

OK guys, the pinout problem is sorted thankyou so much, I should have said, but I'm not using an Arduino board of any variant, as i basically have made my own complete board using a blank 1284P (40 pin), as its a prototype, I'm using an adafruit micro SD (just because the buffer IC and 3.3v reg are on board).
Program is running 100%.
I have a Modbus stack running in my application so that is using serial 0, serial 1 is not used and i have used pin 10 as my CS pin for the SD card (as you correctly noted PD2), I have compiled my software and exported to .hex, and used as instructed AVR copy to make the FIRMWARE.BIN file, however it does not load the new flash file, I have tried holding the CS pin low, but this makes no difference.
I am using the petit FS library in my application to load a config file and that runs fine, bootloader does not seem to read the card on initial start (LED on the SD card does nothing).
Im wondering if this could be a fuse setting or lock bit? i have added an ICSP port onto my board but this my USBASP programmer does not find the chip, so i currently have to keep removing it to plug into my ZIF programming board to reload new programme. Im fairly new to programming (getting there tho), so i havent got my head around the Lock bit settings, but i dont want to brick my IC (apparently thats easy to do), any ideas why the BIN file is not being read on startup? when i exported the compile hex you get two (one with bootloader and one without) i used the one "with_bootloader.mighty-1284p" should i be using the other file without bootloader to create my BIN?

Many thanks

Im wondering if this could be a fuse setting or lock bit?

The correct fuses should be set when you do Tools > Burn Bootloader. I did fairly comprehensive testing with ATmega1284P before the release but there are a lot of possible combinations of settings so it's possible I didn't test your exact configuration and there's a problem. I'll try to get around to doing a test soon.

i have added an ICSP port onto my board but this my USBASP programmer does not find the chip

ICSP uses SPI, the SD reader uses SPI also. So that statement makes me suspicious. However, if I understand correctly, you've already verified that the SD module is working correctly.

[Jono72]

Yes everything working OK, ICSP is now working (I had the MISO and CLK pinout incorrect) as does the SD when running, ive had a look a fuse calculator online, I now understand how those are set but Im not sure what all the options provide, it just doesn't seem to access the SD and load the BIN file on boot as it should, is there a fuse setting that allows SPI to be initiated on boot?

Hi Guys, I know you are all very busy but if anyone cane me with this I would be most grateful, its driving me nuts.
So my Atmel 1284P is working fine, pinouts, SD card, ICSP programming socket all work fine, yet I cannot for the life of me get this bootloader to work, I am using CS on pin 10, as I have checked and all the advice back seems to be not to use Pin 4 (SS), I don't belive that's a problem because the SD card runs fine in the application, if I use either Visual Studio or the Arduino IDE the Bootloader does not seem to install correctly, I decided to use BIT BURNER (as its the only one I could find that supports 1284P) to try and load the bootloader direct I used "atmega1284p_var2_cs10_16000000L.hex"

this is the message from AVRDUDE when I try to load it.

avrdude.exe done. Thank you.

What am I doing wrong, I have followed the instruction, and checked and double checked fuse settings, I increased the bootloader size to 4096 in the fuse settings, yet still I cannot get this to load the new BIN file.

Any ideas anyone??

if I use either Visual Studio or the Arduino IDE the Bootloader does not seem to install correctly

Please provide more information on what you meant by "does not seem to install correctly".

I decided to use BIT BURNER (as its the only one I could find that supports 1284P) to try and load the bootloader direct I used "atmega1284p_var2_cs10_16000000L.hex"

this is the message from AVRDUDE when I try to load it.

Is that the message from when you're using BIT BURNER?

We'll continue the conversation here:

and then come back to GitHub if it turns out the problem is caused by a bug.
