--- Quote from: robca on September 26, 2023, 03:59:33 pm --- Protip: don't buy an FPGA from an Aliexpress seller with 90% rating. Desoldering and resoldering that many pins risks damaging the PCB, and you don't want to discover you got a bad FPGA (or even a different chip with altered markings) after soldering it (and having to remove it again) --- End quote --- NOT terrible as above description, but NO select cheapest seller, what price, what goods 。 |

Looks promising. I had good luck with this wire for super-tiny soldering jobs https://www.remingtonindustries.com/magnet-wire/155-c-polyurethane/?_bc_fsnf=1&Wire+Size%5B%5D=40+AWG&Wire+Size%5B%5D=44+AWG. The coating is easily burnt off with a slightly hotter soldering iron, and the wire is easily solderable after that, with the coating still protecting the rest of the wire. I solder/strip 2-3mm, then snip to leave only a short solderable section of the wire. |

Looks like there is new hardware on the DSLogic U2Basic The FPGA is no more a Spartan6 now is a PANGO PGL12G somebody knows if it can be upgraded too? |

You will need to trace the connections between the memory and FPGA, but without the exposed pins, I doubt you'd be able to make this work. Worse: in order to make DSView recognize the hacked U2Basic as a Plus, you need to change the device ID so that DSView can upload the right FPG bitstream. The new FPGAs use a different bitstream, so you'd also need to figure out if there is a U2Basic and Plus for the PANGO, and change the device ID that way So, all considered, unlikely it will work unless you can get both a new U2Basic and new Plus, and figure everything else out... |
