Is there a "How To" on flashing a 328 with the new HAH Firmware?
24 October, 2011 - 21:25
Hi,
I have a few 328 chips and would like to flash one with the latest firmware. Is there any instructions on this? I have looked around but can't find anything.
I have an arduino board and an FTDI cable, so could use one of a few approaches. I was thinking of burning the arduino bootloader and then just flashing the "liveboxHAH" code onto the chip.
I think my quiery is around the chip running at 7MHz, do I need to set some fuse bits? Or will I be able to get away without doing that?
Cheers

Yes this is doable
Dan,
This is definately doable. In fact I've done this myself and I have v3.4 running on a 328 with the Arduino bootloader. The only thing you need to keep in mind is that that the code must be compiled using 7.xxxxMhz clock. The easier route would be to attach the Arduino with the 328 chip and bootloader to the HAH and download the pre-compiled HEX and follow the same process as written up for the jeenodes on flashing from the HAH itself.

PS: you don't need any special fuse bits etc.. just whatever the defaults are for the Arduino bootloader is fine.

Is it possible to do this
Is it possible to do this with a HAHNode?, not sure what the bootloader Brett refers to is?
Thanks

Sorry?
Sorry what is your question? I'm not clear on your problem?
The Bootloader I'm refering to is the one that is shipped with an Arduino, HAHNodes and JeeNodes You require a bootloader so you can flash .HEX file from the HAH or from the PC without having to need a ISP.

The question is :I have a
The question is :
I have a HAHNode (Jeenode) (or will have as soon as it arrives back from Derek;-))
I have an old 328 chip for the HAH since I ordered a new one from the shop., but the new one is only v2.8 and I want to update to the latest 3.x version as I have had some RF issues (if I understood the other thread correctly).
So, I want to update my old 328 chip (running v1.something) to 3.x using the method you link to above using the HAHNode. Sounds like it will work, just want to make sure.

HAH chips did not ship with a bootloader
Derek does not flash down a bootloader when he ships the HAH chips. So your existing v2.8 HAH chip although perfectly fine can't be upgraded easily until it has a bootloader on it. You have a couple of options I guess.
1) Buy an ISP programmer so you can flash down a bootloader and/or HEX file's directly.
2) See if anybody on the forums can flash a bootloader for you.
3) See if anybody has a spare AVR with a bootloader and you can trade chips in the post :)
I have mentioned to Derek that in future we should ship with bootloaders, not sure if the new v3.4 have bootloader on them or not (I don't do that side of things) initially we did not as it was an untested configuration - but since then I've had mine running v3.4 with a bootloader quite nicely.

I can do it (possibly)
Never done it but i do have a isp and 500 programmer along with avr studio v4.
now is there an ELF? or ELM? (cant remember the exact file type) avalible as this sets all fuse bits etc etc correctly (as i understand it)
I do have a 3.4 chip and a spare 328 so i may have a go at copying tommorrow but as i say i am new to these mega chips.
I live near MIlton Keynes.

The correct fusebits will already be set
I do this when preparing all HAH AVR 328s. You only need to flash the new .cpp.hex file.
Alternatively, I'm happy to re-flash a returned 328 chip with the latest firmware (so long as you include a S.A.E.).

I don't mind either
I know Derek is a very busy person i don't mind doing a "swap" over as long as postage is covered.
dean
P.S Derek do you have an ELF file for firmware? (production version of AVR studio software)

Flashing the HAH firmware
I don't use a .ELF file when flashing the HAH 328 chips.
If you want to flash your own chip, simply follow my notes at http://www.dbzoo.com/arduino/isp_with_stk500
The latest AVR firmware hexfile is at http://code.google.com/p/livebox-hah/downloads/detail?name=AVR-r271.hex
Cheers,
Derek.

Thanks
Dean and Derek
Yes, I thought Derek is busy as he is never home.
Dean, I dont have your address, Dont know if this forum supports PM?

There is a slight error
In Brett's URL for the hex code use this to see a list http://code.google.com/p/livebox-hah/downloads

Sorted Yet?
Dan,
Did you get sorted with a replacement 328, if not let me know and I can do it for you,
Karl
There is a write up for this somewhere which I followed no problem. I will have a dig round for it
Here it is: http://www.dbzoo.com/arduino/isp_with_stk500
