Re: Hedghog standards converter
Hi again,
After Aliexpress (shame on them) refused to reimburse me the full amount for the faulty boards, I had nothing to lose so I made an attempt at repairing the boards and I managed to get both faulty boards into working order -yey! Here's what I did:
- First I added a solder joint next to the power LED to connect it to ground.
- Then I fluxed all the pins of the FPGA chip with a "Stannol" fluxer pen.
- While applying slight pressure to the FPGA chip I heated the pins on all 4 sides with a hot air tool until I could see the solder melting.
- Then I fluxed and re-soldered all the pins of the EEPROM and the headers
After this procedure the board would still not flash the three LEDs, so I assume they come unprogrammed. Unlike before they now got recognized by the Altera programmer though. So I gave it a try and was able to program the first board -LEDs performing the "Hedghog flash" sequence after a power cycle. Then I applied the same procedure to the second board and this now could also be programmed.
Both boards work when inserted into my Hedghog board.
The conclusion from this experience is that I will get a hot air soldering station and some more SMD tools.
Cheers
Semir
