Well done Smiley. Nice work.
New firmware update: "ButterflyBoot v1.1L.hex" released.
It is the fully functional revision of the stable "ButterflyBoot v1.1" release, with the Lock-bits writing feature enabled.
It is only 482W long, so it still is under the 512 Words barrier, and fits into the third bootstart position at the address 0x1E00!

Great George!
You should consider consolidating this into a tutorial and posting it on the Tutorials forum, so that folks can keep track of this in one place. I think this has far more use than just to solve the 0x940c problem.

Another thing to bear in mind with Giorgos' loader, the small size allows one to add
additional code in the smaller boot memory section. I'm using it in a special purpose
application which requires that various port and user IO hardware be initialized so that
among other things, various text prompts can pe presented to the operator during
upgrade procedures. Nice! Thanks Giorgos!

Dan,
Those BF that locked up -- what were the fuses set to when prior to
"unlocking" them? Just curious...

I have Butterflies that lock-up regularly.
However, I am a newbie, if someone could guide me I could check the fuse settings before I restore them next-time. |

Connect ButtLoad to one of them, then in the AVRISP programming window, select the fuses tab. It will read the target Butterfly's fuses automatically, and you can change any of them from that tab also.

Looking at the bootloader code, it seems it activates the lockbits, rather than the fuses (a fuse is set, however, which allows the bootloader to manipulate the lockbits) so next time you get a lockup, you should see the Lockbits in the appropriate tab set to something other than "No Protection".

I'm ready to start "slammin" programs into these ButterFlies again.
I'd like to tryout Giorgo's GeoLoad Version1.1(L) but I'd also like to try the new "Offical" one that's going to be shipped with new BFs.
However, stupid me doesn't know where I saw the link to download it?
Can anyone help?
PS. Any changes to GeoLoad 1.1L since I downloaded HEX File on March 8th?
Were there not a few last-minute changes for an AVRDude related issue? |

| If I am understanding your question correctly you can find a link to Giorgo's (sorry if that is misspelled) thread 9 posts (or so) above your post RetroDan (in this same thread). |

Thanks Steve, but I was looking for a link to the new BootLoader from ButterFly/AVR Develpment team. They also wrote a new one.
But thank you anyhow for your help. |

| How about the 13th post down from the top of the ninth page of this thread. Sorry, I don't know how to do the hyperlink (or whatever it is called) thingie. If that doesn't work try a search on member "eieland" (without the quotes). He/she only has 13 posts so it shouldn't be but so hard to find that post. |

That would be back on the previous page, page 9. Have a look near the very bottom for the post.

Okay, I have ButterFly locked up again!
Please, no Flames this time!
I'm trying to be helpful...read on.
I'm either the owner of some very "touchy" BFs or my setup here is problematic. The DB9-DB9 cable I am using is rather long and looks fairly thin so I don't think there's much sheilding. I have four computers side-by-side and at times the monitors interfere with each other, so there's a lot of EMF. I also have Flourescent Lights which make some circuits go crazy. So to put a fine-point in it -- I glow in the dark. <smile>
This seems to point to the possibility that garbled xmission of data is probably the main culprit. I get a lot of BF lock-outs.
I don't know much about fuses and locks yet, but as promissed I am going to enter the data as read from a "locked" ButterFly using Dean's excellent ButtLoad program loaded into another ButterFly. (I have not setup my STK500 yet).
I hope you find this information useful and would appreciate feed-back
-------------------------------------------------------------------------------------------------------
AVRISP:
Entering programming mode... OK!
Reading fuses... 0xFF, 0X98, 0xE2... OK!
Leaving programming mode... OK!
LOCKBITS: (These are the ones shown with a check-mark)
[v] Mode 1: No Memory Lock Featured Enabled
[v] Application Protection Mode 3: LPM & SPM prohibited in app sec
[v] Boot Loader Protection Mode 1: No lock on SPM and LPM in Boot Loader
(No other Lockbits show checkmarks)
FUSES:
[v] Brown-out detection disabled
[v] JTAG Interface Enabled (JTAGEN=0)
[v] Boot Flash section size=1024 words @ $1C00
[v] Boot Reset vector Enabled (def addr=$0000)
[v] Int RC Osc; Start Time 6 CK + 65 ms
** In Addition Fuse Marked "Serial Program Downloading (SPI) enabled (SPIEN=0)
is filled-in with grey color and a RED Question mark[?}
(No other Fuses appear to be checked-off)
-----------------------------------------------------------------------------------------------
Which are the problematic Fuses/LockBits? |

I would imagine:
Quote:
[v] Application Protection Mode 3: LPM & SPM prohibited in app sec
That's stopping the bootloader from writing new data to the application flash space. When you unlock the Butterfly, can you follow the sequence I posted earlier, loading in the bootloader into ButtLoad's storage and then reprogramming the locked butterfly via that? I'd be interested to see if it works...
- Dean
PS: ISP fuse is disabled (gray box) because you cannot use the ISP interface to disable itself for safety reasons. |

Okay what I did was restore the locked ButterFly to the original program that was shipped with these units when new, then went into AVRISP and read the Fuses and LockBits and the only difference appears to be with the LockBit:
[v] Application Prot Mode 1: No Lock on SPM....
So it would appear that this LockBit took the Functioning ButterFly from App Protection Mode 1 to App Protection Mode 3.
Is that inline with everyone's assumptions?
I'm to "burn" GeoLoad Version 1.1(L) from Giorgos Next and test it. |
