Re: [Unlock] Another UIP1868P unlock thread
said by rcilink  :If you find this to really be a JTAG interface, let me know. I've been a bit busy, but did build a simple JTAG cable for this connector based on Lattice documentation. If this approach doesn't work I might have to order the buffered Lattice cable (it's about 50 bucks, though, compared to my $7 home-brew).
said by rcilink :I have both the UIP1868P and UIP1868G devices. Yes, the "G" (generic) version firmware is very different. Unfortunately, I don't have access to a -G version of the UIP. Is the VoIP board in these two the same, i.e. are the -P and the -G versions truly the same hardware, just with different firmware?
said by toro :BTW, the connector that you labeled as "probably proprietary" is part of all the Packet 8 adapters, including the ones in the "old generation" like DTA310, BPA410, etc Yeah, I saw that in another thread about the DTA-310, which is why I labeled it that way. Theoretically, if there is advanced functionality (such as IDE - not likely, just saying) present, it should show up in the JTAG chain. | |

Theoretically, if there is advanced functionality (such as IDE - not likely, just saying) present, it should show up in the JTAG chain. That "proprietary" port on the VoIP board is known as the Host Interface. You need a HOST cable, connected to a STIC box, connected to your PC... so you can burn firmware directly to the device.
I have not been able to obtain this cable and STIC box device. It was something Netergy sold as part of a development kit... way back when.
See link: »www.design-reuse.com/news/5917/n···ogy.html
Netergy was a division of 8x8, the division that made the Audacity T2U DSP, etc.
I don't know today where it is, but Myson Century and LeadTek had been making devices using the same T2U DSP model.
Maybe if there were any interest in this, we could get 8x8 to re-issue a development kit (I'm sure it would be a cost involved, but still...).
Also, if they make it licensed similar to the Apple iPhone, they could retain rights to apps or firmware designed using this kit. | |
