I read it straight from pic. It's not protected and it can be modified. But ar9331 (open-wrt) module can re-write that code. That's why you can update fw in S1 controller to S3 controller. I have no clue what language was used to program it. Now it looks like ar9331 module don't work with (usb) full-speed devices without passive usb-hub which converts signal to high-speed (12mHz --> 480mHz). That explains why BM used that painful Nec's usb-hub chip in their circuit and moved to BBB.
The design also gives me hints how they propably have done their newer controllers. I think BBB and it's software can update code in Altera-chip, which is used in lower pcb. That lower pcb with Altera is just one kind of uart-adapter board. So I believe that lower board can be used with any BBB rev. from BM. But I'm only guessing here.
All very interesting i have spent time over the Years with other Pic based systems and have ICD / PicKit2 etc so may take a look sometime, however already have too many unfinished projects on the go.  I am sure you are right on being able to update the Altera code. I also agree with you on that lower board being common, albeit that they have changed the number of Hash Board connectors I think that you can load S5, S5+ or S7 Code into any of them?Rich This is exactly what I mean. I can't confirm this 'cause I don't have S5+ nor S7. I did some experimenting with pics but it was years ago and no usb back those days. I'm in the middle of reading a very long topic of this ar9331 usb problem. It looks like there's a bug in it, hw-level. |

I have loaded and run the S7 code on my S5 and it runs on the S5 and it recognises the chips etc but does not hash. My guess is that this is because the codes sent to initialise the chips are different from BM1384 to BM1385? I think from what I have seen that the early S7 used an S5+ controller, also have definitely read of S5 & S5+ being interchangeable. Rich |

I think you're right about that initialising chips. And thanks for the information, it was pretty much what I expected. Now we "only" have to make our own Altera board to experiment more. I have too many projects...

And now I can confirm that this s3-controller needs an usb-hub chip to work. It doesn't matter what chip, but 12 to 480Mbps is needed. Works well with some tusb-chip.

No news, it is much tougher project than this adapter. And I've been busy with some other things. But I still have some ideas, so don't lose your hope...

Have you made a S3 board?
Or if possible i can send you mine and try to flash firmware on it.
Try to update and did not work.

I managed to get it working. I ordered a batch of pcb's with new modifications to the circuit. They left from China at Christmas eve, so I expect them to arrive next week. It works just like original controller though I use some different parts. Main changes are that this controller has different usb-hub chip and ar9331 module is from different manufacturer.

Some update. I finally managed to build my own S3-controller. Same fw than original controller,ofcourse, but some different chips and module.  |

@pinHead do you have any others or a listing for the S3+ ?
