Would you mind dumping the winbond SPI flash and posting it here?
attached...
You'll need a CH341A (preferred)...
This is totally shit programmer...
I bought EZP2019+... Each reading get different result...
After that order SP16-B (www.sofi-tech.com) this one read stable.
Hi UniSoft,
I'd like to say thank you, since you made my day.
I got a new version of 1013D from Aliexpress (BNC inputs mechanically better protected and also power button is now more hidden), but the seller shipped a chinese version although an english version was advertised. So the device was pretty useless for me. On top of that, the seller wasn't really willing to fix his fault, so let's see what Aliexpress is finally suggesting.
In the mean time I spend some hours of investigating the hardware and tried reading out my W25Q16 with the chinese language user interface with a cheap CH431A programmer (and yes, it works perfectly, if you do it right!). Since it went well, I continued with flashing back your file, hoping that nothing else had been changed from the old to the new hardware version. At the end, I've now got a new version of 1013D with english user interface up and running. The only difference between the english and the chinese version is, that there is a welcome screen included with the chinese version, which pops up quite early after pushing the power button, whereas the english version remains dark for quite some time, which confused me the first time when powering up the device, but since I know it takes a bit longer to display anything, its ok.
I noticed some differences with respect to the new PCB: The solder pin for the RESET line of the F1C100s has been removed. The line needs to be pulled low now at the pull-up resistor. You can either solder a thin wire to the resistor or, as I did, use a pogo pin. Make sure you ground the side of the pull-up resistor, which faces the F1C100s.
The procedure to correctly readout the W25Q16 with a CH431A programmer is as follows:
Pull down the RESET line of F1C100s
Connect a suitable SOIC-8 test clip to the EEPROM and connect it with the programmer
Power on the scope
Read / Erase / Program the EEPROM
I added the chinese version to the attached ZIP file.
Best regards and Merry Christmas!
