Skip BAD BLOCKS on nand Reply  
hi is it possible skip bad block on nand when read/program with VP-890 ?
Last post : Re:Skip BAD BLOCKS on nand Reply: ciariello
mmm...no i am no a manufacturer i am only your custmer and i think can be a good idea to give the possibility to choose whether to use the simultaneous VERIFY or not. i think is better (i know is more slow) verify at the end of programming so you solve the bad block nand problems.we know 60-70% of nand chips has bad block(it"s normal) and would be a nice feature CAN to choose

Usually, if the chip have config program function, the software will add extra 16byte automatically, and save the config data in it. So you can look at extra line.
If you didn’t save the config data in the file. When you save the data, you can modify “To Buffer Addr” and “Buffer Size” in the ”Save Buffer To A File” window.
If the chip didn"t have config program function, there is not extra line.

VP280 can read but not write/erase Reply  
My VP280 can read but not write/erase. All devices work with other programmers so I know VP280 is faulty.Tried Wellon 4.3.4 (and older) on multiple PCs. VP280 firmware 9.0. All self-tests run ok and all VCC/VPP voltages are ok.
Firmware upgrade: Link LED flashes green 3 times, G/E LED is off, Wellon hangs.Tried J1 (short J1, connect USB, run Wellon) but cannot communicate with VP280. Link LED is off, G/E LED is red.
I cannot see obvious faults inside. Can you suggest any components to replace?

VP990 problem Reply  
Hello everyone
I have received my new programmer today, VP990 which i bought from an official distributor in Europe
Do i have to and how can i register for the guarantee?
Also, when i try to read a chip, always shows as chip blank FFF
i used my old programmer and it works ok
Any ideas please?

It would be technically possible to add the device GAL26V12 to the VP-380 programmer device list?
Best regards.
