I have a problem programming PIC16F77 micros.I have tried with several different micros with the same result.
Programmer is VP-390
>>.Auto Program......>>.Erase......>>.Blank Check......>>Device Address:00000000H Device Data:7FFEH Buffer Data:285DH>>Auto Program fail!>> 7.63Sec
" Checksum mismatch. the installation is corrupt or has been tampered with. if you downloaded this file from the internet, try downloading it again"
I have tried 3 times and it is the same problem !The system is Windows 7 64bit
Please fix this issue
>>.Auto Program......>>.Blank Check......>>Device Address:00000000H Device Data:FFFFH Buffer Data:00FFH>>Auto Program fail!>> 2.13Sec
This error occurs 100% of the time, no matter what 4096 EPROM I use. Blank Check passes successfully when checked by itself.
It is probably compatible with something already supported. I need support for the PLCC one.
Any chance on supporting Samsung flash chip type S29GL128N90TFIR2 on VP-490 programmer? It"s the TSOP 56 version.
Here"s the chip datasheet:
>>.Read......>>Read OK!>> 6,53Sec----------------------------!
>>Man.Code:20 Dev. Code:D4>>.Verify......>>Device Address:00000057H Device Data:9622H Buffer Address:000000AEH Buffer Data:1622H>>Verify fail!>> 0,92Sec
still got problem when programming using my brand new vp-490
this time with ST M27C1024
still pragram then somes seconds after start,program fails!
note that:-thoses eprom can be programmed on an vp-280 (so its works not bad eproms)-i"m using latest software (02/11/2012)-i"m on windows 7 64 bits and tested on windows 7 32bits too
-i"m using CORRECTLY my vp-490,that"s means that i put ac adapter before plugin USB cable and i always use ac adapter
thanks for your help
Any chance on supporting Samsung flash chip type K9F1G08U0B-PIB0 on VP-490 programmer?
just received an brand new vp-490
when i try to program eprom like m27c322 or any other kind of eprom,just got an "auto program fail!"
what"s wrong?thanks for your help
note that ac adapter is plugged in,give 9v but when i try self test,i can"t have exactly 3v (2.8)/12v(11.92)/25v(24.02) using my "standard st-3341 multimeter""
just downloaded lastest,version,all is working perfectly (got an communication error at the finish but its ok when using another eprom)
thanks you all of you,you"re awesome!!!
just got an vp-490i can"t update firmware with lastest software version(doesn"t works at all)
So i used older one"s in the cdrom (4.4.0) but i"m still at firmware 16(everytime do an update but nothing change)
what"s wrong? thanks
BTW, is the VP-298 the same as the VP-290? Because there is hardly any mention of the 298 on the Wellon website.ThanksDave.
* Can now load CUPL Vector information* Vector limit has increased to 3000, from 100. (loading is slow, but for < 3000, it works)* "K" inverted clock support has been added.
i just buy an vp-290 which rocks
i don"t understand why i can"t program eprom like NEC D27C40960 or equivalent when you can do it whith an vp-280(older) wich is compatible with less composant
it is a way to update the compatible list of the vp-290 ? thanks!
by the way,if i want to program an ST M27C322,which adapter should i buy?
What I must do?
did you install the software before or after plugged the programer in the usb port?
