Willem issue with LPC

[Arakon]

I got a willem 5.0 programmer (onboard LPC socket).
No matter what software version I use, I am unable to erase or write to 49LF020 or 49LF020A.
Erase says it was complete, but chip remains as before, writing fails too of course.
Also, ID shows as [--].
I CAN read the chip perfectly fine, so I know for a fact it's not a contact issue, bad chip, or whatever.
I've seen a whole lot of people on google with the same issue, but I also know some people used to program them with a willem just fine. Any ideas?

I believe this is an issue with the programmer software, I have experienced the same problem before

[Arakon]

Yeah, but since the chips are supported for years already and people have flashed them, there's gotta be a reason why it doesn't work for some. I tried like 8 versions.

HI Arakon.

Your problem is pretty simple and easy to fix.

You are having bad pin connections and therefore no chip id.

If you look at the lpc socket on the programmer u will notice that is is in fact quite deep. TOO DEEP in fact! so the chip when inserted actually goes past the point it should where the pins are the tightest..into a kinda void below.

i personally used a blob from my glue gun so as to raise the chip whilst it sits in the socket so as to now sit flush with the top of the socket. this worked first time and proved to be a 100% permanent fix for this problem with the willem programmers lpc socket for me. Hope this helps u out as many of your posts have done for me over the years

Just a side Note,

u say its not a bad connection because u can read the chip fine, i completely disagree..

A blank chip id is a 100% classic sign of bad connection, although the software itself will in fact tell u its reading the chip...DO NOT BELIEVE THE SOFTWARE!!! The software will only read and write correctly when it has a proper chip id....no chip id = bad connection = fail erase & fail write as it cannot communicate with the chip properly!

"btw should anybody wonder why i have hardly posted anything before..who says i havent lol..."

Hope this helps somebody...

Please dont associate me with Gigabite/giggles or whatever else u want him to go by. HE is the main reason i do not normally post anything on the forums. Mainly because i refuse to talk to kids online (in the uk its called grooming and highly illegal)

Usefull posts with information and questions that help other members im sure are always welcome on the forums, pointless posts asking pointless questions that have already been answered achieve nothing than to CLOG FORUMS FULL OF CRAP!

Your post above gazcoigne..was neither usefull or constructive and only INSULTING to myself and childish! EXACTLY THE REASON INTELLIGENT PEOPLE HAVE BEEN PUT OFF COMING HERE!!! THX FOR THAT REMINDER!!  YOU just put me off posting AGAIN!!

[B1N4RY]

Arakon, found a solution yet?

[zillionare]

I have one(willem red board) myself and might know your problem.

msg back if your still having probs.

well when you are labelled as a new member and you come off with a line like

"btw should anybody wonder why i have hardly posted anything before..who says i havent lol..."

sounds like something he would have said

genuine apologies for labelling you as that fool i know that was an insult!

anyways back to topic sorry for going off on a tangent.

I tried that (using a piece of cardboard so it's easily removable), and the result is 100% the same as before. I can read the chip, the data it reads is correct too, but I get no ID, no erase, no write.
Also, on a side note, I've used those "deep" sockets in other projects just fine before.

@zillionare: That's the one I got, pcb 5.0.

[notsonoobesq]

@Arakon

U havent provided many details on ANY settings u are using, operating system in use, or any info really that could possably diagnose the problem further.

Are u powering by the usb (normally crap) or via the power socket? 

if using xp have u tried the xp_stop polling.reg???

Install Programmer follow below.
1. Install Version 0.97ja
2. lnstall Version 0.98c ( PBC35 [0.98c] )
3. install XP_stop_polling.reg (stop polling printer port)
4. Run Program EPROM35 ( PBC35 [0.98c] ) again

Although i reiterate REGARDLESS of a correct read, no chip id is normally indicative of a bad connection.


@gazcoigne.

I respect your knowledge and input on the forums, but in no way want to clog more threads up with pointless waffle devoted to that person Gigabite. i feel it only encourages him and lowers the forums further.  though  should members decide to have a small jibe at EVERY new member who may or may not be somebody they dislike, i can only see that progressing to mayhem (online paranoia isnt good)

THANK YOU for your apolagies, gratefully accepted and look forwards to speaking again in a more pleasant light!

[Arakon]

I've tried XP in a virtual machine and natively on a pc, powered by USB and a power supply, the printer port polling registry setting is set, I'Ve tried 6 or 7 versions of the software ranging from .97ja to .98d10, etc. The issue is always exactly the same. And the exact same issue is happening to a whole bunch of other people, even with different willem board revisions, I doubt they ALL have contact problems with only lpc chips. dip settings etc are of course set like the software shows.
I also tried a 49lf020A, it returns manufacturer ID 0x58 (which is wrong for SST), but also 00 for the chip ID. so it's getting something apparently, it's just wrong.

[notsonoobesq]

Very strange indeed!

I am using Exactly the same board as you, running in windows xp native.
parralel port 378/irq 7
epp
epp 1.7
i do not personally use the xp polling (only suggested it as a possable fix for you)

I can only state i had THE EXACT SAME ISSUES   spent days on this with no support help and reading the same posts i am sure u have now done to no avail, to only find it was indeed a bad connection problem which was only cured by raising the chip so it was flush with the top of the socket. (im sorry to keep repeating this) Your problem is 100% a bad connection with the chip

Using software version 0.98d9 (which works perfectly without any errors at all in software. sorry B1N4RY your wrong ) on board version 5.0 your correct Electronic id should be

Manufacturer 0xBF SST /Sanyo
Device code 0x61 SST49lf020
i can still replicate your results instantly here btw by just inserting my chip in the socket on an angle giving the chip bad contact and get Exactly what u state??? the only other thing i can suggest to u is to get the old multimeter out and start tracing connections...NIGHTMARE!!!

ps. in case it helps jumper settings next to the plc32 and lpc socket i use are

open
open
closed

closed
open
open
open

The jumper above the plcc32 socket = closed
with jumper on the 5v for power (jumpr near the usb socket)
Both jumpers onto pcb45 (near printer cable socket)

[Arakon]

ugh.. found the issue.
The manufacturer had put an extra jumper on one of the jumper sets, which changed the config from "normal" to "w27cxx erase". Of course, all the manuals said "leave the jumpers as they were at delivery".. idiots.
Removed the jumper, now it's working perfectly.

[B1N4RY]

Which jumper did you remove? all of them?

[Arakon]

Nope. There's a set of jumpers right of the sockets, which has several possible positions. Normally 2 jumpers are supposed to be there, in this case three were.

[B1N4RY]

Thanks for telling us. I'll take a look at my programmer when I dig it out of my garage
