Re: c0nb0x

small bump
the source code for c0nb0x is now available (v1.01) on the website (see first post and follow the directions)
it's possible to build this on OSX and linux (some adjustments might be required)

warning: it's an ugly pile of sh** code, you've been warned
any questions and/or assistance in building on other platforms - feel free to ask me :wink:
We are here too: irc.freenode.net >>> #x0xb0x

Anyway, thanks a lot for c0nb0x.
It's a great little tool ! :)

no need for a menu
just import a .cxm file full of zeros

in the c0nb0x v1.01 .zip, there's a file "EMPTY.cxm"
if you do "Import EEPROM" - the whole file will be imported (thus it will overwrite not just the patterns but also tracks and such)
if you do "Import Patterns" - it will only overwrite the patterns

Hi again,

Just a stupid question about c0nb0x.
Is it possible to save/backup just selected banks ?
(e.g. save banks 11 to 16 and erease other banks).

Regards,

Guillaume

nope
you can export/import all 128 patterns at once to/from a single .cxm file
well, you *can* using a HEX editor, if you really want to

for the stock firmware and sokkos (and any other FW compatible with those) - the pattern length is 16 bytes

the CXM file is pretty much raw binary with a header on top, more info here:
http://antonsavov.net/cms/projects/c0nb0x/dev.html#cxm
the data begins at the "data_offset" but that's typically 18

hello,
thank you Antto for all this work !

I'm trying to use the c0nb0x to update the firmware to 2.10 in my
n0nx0x2 (yes I have the cpu mod and everything is running fine on the 2.09 firmware).I was able to do it last time but this time there is a an issue.
See print screen please on the link below, what's wrong?
thank you !

Re: c0nb0x

that's because c0nb0x at least up to the current version (v1.01) is meant to flash the original x0xb0x cpu
the cpumod uses a completely different bootloader (based on stk500v2), which also runs at a 3x the baudrate, and c0nb0x doesn't work with it

to update the firmware on the cpumod, you can do it 2 ways:
via USB (with avrdude) or via MIDI Sysex (with a MIDI-librarian app)
more info here: http://antonsavov.net/cms/projects/n0nx ... l#fwupdate

Dear Antto,

i have the problem to upload the latest firmware. I do it with C6 from Elektron. It looks like it works, but i don't now.
And with c0nb0x i get error messages.
Attach you will find screenshot, hope it helps.

All the best,

waldemaR

hold on
if you're trying to update the firmware on the cpumod (x0xlarge) - don't use c0nb0x
all versions of c0nb0x up to the current one (v1.01) can flash firmware only on the original cpu (atmega162)

for the cpumod, use avrdude (USB) or MIDI (sysex)

also, it's not visible from the screenshot what port the x0x is on, but i highly doubt it's COM1
check in the device manager to see which port the USB<->Serial driver is on, and use that port with avrdude

Dear Annto,

thank you very much for the quick reply.

But how i can check this that everything works as accept?

All the best,

when you follow the procedure, things should work
there is a video demonstrating how the process looks like.. avrdude was used in the video, but it's pretty much similar when doing it over MIDI sysex, just with a few differences:
- via avrdude, by default there is verification - avrdude reads back the data after it has been written and compares it with the hex file
- via sysex - sending the data takes more time (because midi is slower), and the communication is just one way, so there's no way for the bootloader to tell if something went wrong or not

but basically, after flashing the firmware - the bootloader jumps to the firmware, and you should have the x0x "working"
if something went wrong - the firmware would probably be semi-corrupted, and then trying to run it would result in maybe faulty operation, but more likely a complete unresponsiveness.. but this rarely happens

Hi community

c0nB0x 1.0 is supported for OS X Yosemite 10.10.1?

Thanks

i don't have anything osx myself, i develope the app on windows.. so i don't know if it'll work on a given osx version or not
you could try it out and report if you experience any issues..
