Bankstick gets formatted on every startup

[Marxon]

Hi erverybody!

I have got a problem with my Bankstick:

every time i start my sid it starts formatting my bankstick :( and i can't upload any patch

I have connected 8 banksticks. also a test with only one doesn't help.

There is one strange thing: it starts formatting always with patch B then C, D ...and patch A at last.

Is this normal?     

edit: do i have to put an chip an every socket? or can i leave some out?

Hi,

yes the order is correct, but of course it's not ok that the BankSticks are reformatted on every restart.

Two questions for my own understanding: is your MIDIbox running with MIOS V1.8? (it provides the important brown-out reset fix) - and how does your MIDIbox behave if only one BankStick is connected? At how many BankSticks do you notice the problem?

Hi TK!

I just edited my post while you where replying it...

Yes i run MIOS 1.8.

I just finished a Single Bankstick PCB. It is the same problem.          thx BpM

Are you able to write anything into a BankStick? If not, two or more connections of your BankStick board might be swapped.

What happens, if a single BankStick is connected -> directly <- to the core module (not using a special board, but maybe only a socket with some wires going to J4)

solder solder solder......

Power on, Formatting (now starting at patch A), power off, power on AND no formatting anymore!  ;D

Upload patches.... HURRRAY! Works!

To the 8 bankstick problem:

I soldered some wires "in Reihe" and not "parallel" to save solder time can this cause problems?  thx BpM

Morning!

I have worked on my sid the hole night and a friend was helping me...

He soldered the bankstick modul again for me bacause he is much better in soldering,

but it is still the same when i try to use  1 or more bankstick  :-[

The connections are exactly like at your picture TK.    bpm

Thats really strange, I know that the schematic is correct (e.g. because Mike made a PCB based on this schematic, and it works fine). Concerning serial/parallel connections: the SDA and SCL pins have to be connected together, I guess that this is still the case on your module? You should be able to disconnect a wire in the chain in order to check, which one is causing the problem?

Hi TK!

Uff! No. As i said a friend soldered it on a "streifenrasterplatine" with many many bridges.

And i allways said to my friend: "dont solder them all, let's check it before"

but he: "no, no. it WILL work"  ::)

But a (real) bankstick pcb seems to be a good idea. Instead of checking and testing wires (and getting wired)

i try to make a schematic with eagle and etch me a pcb  :P 

ok thanks for ur help (and all this crazy MidiBox tools)  BpM

Just write a mail to mike, he has the .brd file
