Re: Help - Revelprog never worked properly for me

ehi, you're great.
I removed that capacitor, now it is reading always good :D
I will do more test tomorrow, if i will get further reading issue then i will consider to send it to you.
Thanks a lot ;)

Re: Help - Revelprog never worked properly for me

Please, can you explain me where and how to ship it?
Can i send it to you without soldering again the 10 pin strip that connects the 2 boards together?
(i can send you new strip pin if you want).

Re: Help - Revelprog never worked properly for me

You can try to remove capacitor I marked on photo with yellow (it is few pF and is very crucial for high speed SPI transmission, but in latest versions there is software filtering and it can be removed). Ohh sorry, i just see it. Hmm, i don't think so it's that capacitor the problem, because it rea...

Re: Help - Revelprog never worked properly for me

I did many test. Yes, i did try all of the 3 speed option, always behavies the same. Can you explain me which are the filtering capacitor? I might check them with my capacitor and ESR tester. We can check it, and if MCU is faulty we will replace it free of charge. Is it possible to send programmer t...

Help - Revelprog never worked properly for me [solved]

Hello, my revelprog programmer never worked as it should. Since i bought it, i always had to read ROMs dozen of times until i can get identical output file because programmer often doesn't read well (i always used Hex Workshop to compare output file). If you get some difference on few bytes when you...

Re: SPI rom 25Q20BWVIG - Reads only half part. Probably BUG

No, i haven't tried to read or write new chip alone because i have worked on it directly on board (i don't want to unsolder it from new good board). Yes, i've tried to read again old chip alone, i get always same problem (i can't work on old chip while is on old board because it has shorts and burne...

Re: SPI rom 25Q20BWVIG - Reads only half part. Probably BUG

Thanks Michael for updating info. I have also received these chips (alone) and all tests passed and everything works fine (even chip ID is recognized correctly). We will keep an eye on this possible issues and I'll let you know when we find something interesting. Well, then i can't figure out why i...

Re: SPI rom 25Q20BWVIG - Reads only half part. Probably BUG

Hello, today i've received new donor pcb which has same SPI rom chip. Revelprog programmer was able to read it correctly, then i wrote on it my patient rom, no error occured :) Probably it worked well because i used my sata computer power supply and SOIC-8 Clip for read/write directly on donor pcb r...

I compared bytes from saved files with Hex Workshop, if i read rom when the chip is direclty soldered on my adapter i get always same bytes reading (th...
