After a compelled delay I want to announce some upcoming updates I'm currently working on:

  • In-system MCU flashing directly from DOS environment
  • Ability to load 16Kb of custom AVR code to MCU and use it as a co-processor or a DSP
  • Flashing utility for DOS (flash-bb.exe)
  • BB diagnostic / testing utility (test-bb.exe)
  • Documentation for all mentioned above 😵
  • Some minor firmware compatibility fixes

In-system flashing will be available with next firmware release (3.0). However, updating to version 3.0 requires an external programmer. Preprogrammed MCUs with v3.0 will also be available separately at the cost of shipping.

Looks like this would be a perfect fit for a Toshiba T3200SXC. Are there kits available as of now? I tried sending a PM, but apparently I need to post more before that's possible.

Hi,

When I am soldering my board, the Capacitors C28 and C28 are reversed compared to the picture come page before.

Is it normal ?
C28 Grey 1nF
C29 White 10nF

For Rev B boards C28=1nF and C29=10nF, colors could differ from kit to kit

Out of curiosity, did you take the bootloader approach when implementing self-programming of the MCU, or was there a solution you liked better?

Yes, it happened that with a bootloader mcu can be reflashed without introducing any hardware changes

Hi,

did you think about what I proposed you ?
Implement the 8 bit Sound Blaster 16 commands : Set Frequency, 8 bit High Speed DMA signed.
It is "Only" adding existing commands that "No" software will use as the board is seen as a SB 2.0.

This will allow to setup the frequency more precisely and speedup mixing (No more unsigned)

Sure, it is already done in fw v3.0. However, the fw is not finished yet.
I'll compile a version for you just with these commands, so you could test it with your player. Most likely after the holidays.

Hi,

I finished the board and it worked the first time I plugged it in my PC1640.
Unfortunately, I removed it to change the IRQ and it does not work anymore. 🙁
I tries to remove / Plug back multiple times and to clean the ISA Slot, it still does not work.
(Not Detected by Mod Master and other apps)

The adlib part is still working.

Will you do new batches ?

That's unfortunate, but that might be fixable. My first thing to try would be to check/re-flash the MCU. Others might have much better ideas than me though 😀

Yes, Check the MCU, but I suppose I need special hardware for this.
I have an universal programmer (I never used it yet), a TL866, can it be used for this ?

Or I send the board back to LABs so that he check it.

TL866 should work. I am not at all sure it's a useful thing to do at the moment though. You could put in the MCU and try to read it with the TL866 and see what happens...

Hi, In a picture, I see that there are 2 jumpers on the IRQ Part.
I don't know how they are supposed to be configured.

Anyway, it was working before, the problem is not there.

matze79 had similar problems: BLASTERBOARD : A new SB 2.0-compatible ISA sound card

Also check all solder connections, clean of flux from board.

A dit stopper To work after i removed it To change the IRQ i dont thinking is a Soldering problem

IRQ settings are printed next to the logo, so on your photo it is set correctly to IRQ 7. Does it work on your previous setting?
Please PM me with a photo of a solder side.

Yeah my MCU was dead, because of power supply issues, i replaced it with a new one which did the job just fine 😀

i tried to rewrite the old one with the TL866, but it had verify errors, flash failed.
