Problem : bankstick shared between SID and FM box

Testing/Troubleshooting
1

Hello,

It seems that a FM Box reformat correctly a SID FM bankstick although the contrary is not possible.

The SID freeze (each time at the same pach) and reboot when trying to reformat a 24LC256s formatted by a FM.

Is it something known ?

Is there a way to totally reset a 24C256 ?

Thanks for the answers,

Xavier

Hi Xavier,

yes, I remember that this was reported by Seppoman (?) some time ago. I still haven’t searched for the cause yet, but in general I think that this is a “low priority” issue.

You can clear the BankStick with following C program:

Init()
{
  unsigned int addr;
  for(addr=0; addr<32768; ++addr)
    MIOS_BANKSTICK_Write(addr, 0x00);
}
[/code]









Best Regards, Thorsten.

Thanks Thorsten,

I had to install the sdcc kit for that but that was interesting…

The main.c skeleton looks great…

The C functions seem to be very documented (like the rest of the project).. I found how to select the bankstick in 10 seconds…

In the init() the function did not exit from the loop (!!!)… I may have uploaded something wrong.

But

void DISPLAY_Init(void) __wparam
{
  unsigned int addr;

  MIOS_LCD_Clear();
  MIOS_LCD_CursorSet(0x00);
  MIOS_LCD_PrintCString("Formating... "); 

  MIOS_BANKSTICK_CtrlSet(0x01);
  for(addr=0; addr<32768; ++addr) {
    MIOS_BANKSTICK_Write(addr, 0x00);
  }

  MIOS_LCD_CursorSet(0x00);
  MIOS_LCD_PrintCString("Finished....");
}

did exactly what i wanted… Now my MidiboxSID have again its 2 * 24C256…  :slight_smile:
