While dumping many of those Multigame-Consoles & -Handhelds the last couple of months, i designed some adapters for the TL866IIPlus, so dumping the unusual flashrom will be easier in the future.
In this post i will show the first adapter, which is for the MSP55LV650 (64mbit) and MSP55LV128 (128mbit) flashroms.
For all these adapters you will need a TL866IIPlus programmer (basically a TL866 should work too, but is not tested) and an TSOP48 V3 Baseboard:
For the adapter itself you will need the following parts:
- 1pcs of the Base-PCB, which can get ordered here
- 1pcs 1P2T slide switch 2.54 (look at ALIEXPRESS)
- 2pcs female double row pin header 2x12 (look at ALIEXPRESS)
- 1pcs PSOP44 to DIP44 Adapter (look at ALIEXPRESS)
Solder all parts together and you will get this:
Now put all adapters into each other and insert it inside your TL866IIPlus:
- Controll the DIP-Switch (DIP 1) on the adapter-board! It has to be in L-position!
- Open your TL866IIPlus-Software and select the IC S29GL064A10TFIR3.
- De-select CHECK ID
- Click on READ and on READ on the next screen
- You have to get this ERROR-Message! 4 Pins should be not connected, that is correct! (If you have more Pins not connected, re-insert your chip and check your socket-connections, it has to be exactly 4 unconnected pins!)
- Click Cancel and afterwards de-check the Pin-Detect
- Now read the Chip again (Click READ and READ on the next screen), it should read the complete 8mb!
- Save the dump to a file!
- remove the chip from the socket, reinsert it and read it again (Step 2 - 7), compare both dumps and look if they have the same CRC...if not, repeat the Steps 2-8 until you have at least 2 identical dumps!
- For MSP55LV650 you are finished, this chip has only a 8mb rom!
- For MSP55LV128, change the DIP-Switch now to H and repeat the steps 2-8 for the second half of the chip. This chip has a 16mb rom. After you have dumped the first half (DIP-Switch to L) and the second half (DIP-Switch to H) you have to concatenate both 8mb files! Afterwards you are also finished with dumping the MSP55LV128.
I hope this will help some of you getting this stuff dumped!
An blog-post about adapters for the MSP55LV100S and MSP55LV512 will follow in the next few days!
