Revelprog IS and deepspar USB pro

[Mike - USBRecovery.co.uk]

Anyone running both of these on 1 machine ?

Came to do a rom transfer this morning IS25WQ040 and my previously working setup has bricked 2 ROM chips writing the patient ROM to them, initial reading of the bricked ROMs was fine.

Swapped to a second machine and it writes fine to a third ROM but the 2 bricked ROMs wont ID or read.  The only thing I've changed since I did this last on the first machine was installing deepspar stabiliser on there.   No warning errors or complaints about over current and Im plugging it into the motherboard and not the stablizer or from usbs. USB cable was swapped after bricking ROM 1.

[Claude Barras]

I broke my Revelprog as well, they are sensible. They sent me mouser reference to replace broken opto. 

I bought this and it's perfect.

The revelprog is working fine on machine #2 - just not on the machine it used to work on.  I know USB stabiliser does odd things with USB wondering if it's some sort of conflict.

What if you disconnect USB Stabiliser and don't let its software starting up with Windows?

I also use RT809H with Stabiliser but I let it run only when needed.

the deepspar driver is added to non-deepspar drives

Looks like its in all storage and usb driver chains.

Do your systems look like this too?

=========================

do you get 2 deepspar devices?

=====================

The deepspar drive is in every usb device

===================

and all the storage drivers

=== this one only has a deepspar driver - wonder what this even is?

Just one - "Deepspar USB stabilizer USB Device" no "Deepspar USB control USB device" I get another  "Deepspar USB stabilizer USB Device" when I power the unit on with something attached.

I think this machine probably needs a reformat. I don't see how a rom can be bricked without overvolting it though. 

[pbzcbf...@gmail.com]

These are 1.8V devices. Is it possible that the wrong voltage was selected??

[img]

Yes, DeepSparUSB.sys is everywhere on my system too.

But only one "Deepspar USB stabilizer USB Device" in the device manager and no "Deepspar USB control USB device" shown.

And no another  "Deepspar USB stabilizer USB Device" appeared when I powered on the unit with a drive connected.

But when I switched off the unit (with or without a drive attached to DSUS) the Windows device manager acted like when you remove 2 devices, one by one.

DSUS has it's own internal storage, like 50 MB if I recall it correctly. In the beginning, just in case I removed the drive letter from it, what is automatically attached by Windows.

Maybe that internal storage was the second DSUS device what is appeared on your machine.

It has taken some time to set the language on my PC to English but here's the screenshot:

[Mike - USBRecovery.co.uk]

@franc - I thought it was PEBKAC at first too, especially as it's only on a write event. I rarely use it, only really on these drives so it's always at 1.8v  but I didn't actually check it on ROM 1. On ROM 2 I am 100% sure the software was set to 1.8V. Whether that's what was output at the ZIF for the chip I don't know. As it was previously working I would expect so and as it works on a different machine I would think so.  I'll order some more chips from AE rather than ripping them of donors.

[pbzcbf...@gmail.com]

I wonder if the "DEEPSPAR USB Stabilizer USB Device" is the USB mass storage device while the "DEEPSPAR USB Control USB Device" is a "device" that controls the USB power to the flash drive, etc. It might also disconnect and reconnect the USB data lines as a way of resetting the drive without cycling the power. ISTR that DeepSpar did make mention of such a feature.

[Mike - USBRecovery.co.uk]

Bricked another ROM yesterday on machine #2 this time so it's not machine related, that in turn rules out deepspar USB stabiliser and it's software/drivers. I have a working theory on what might be going on though.

I've been disconnecting the reader from the machine to put the chip in the zif under the scope - the software being left open and set to 1.8v, when I put the reader back I think it's seeing it as a new device and resetting the voltage to the default (3.3v?) - despite the open software still showing it's voltage is set to 1.8v from the original read. If the next operation is erase you end up overvolt the chip,  I haven't noticed as normally the first operations are ID / Read - but when I've just neem quickly writing to donor pcbs I've gone straight to write.

I need to meter the reader output after some more testing. 

[pbzcbf...@gmail.com]

ISTR that you had difficulty programming a particular ROM in an older thread. Could the two problems be related?

[Mike - USBRecovery.co.uk]

IIRC - it wasn't even reading that chip. It was from  a 4TB seagate drive, it was another 1.8v chip but wasn't listed as a supported chip - I forget the chip ID. I bought a modded ch341a and it wasn't supported in that either.  At least they have a hardware jumper to set the voltage, if Im right about unplugging it and the voltage reset that's a huge oversight by the software developers.

[pbzcbf...@gmail.com]

ISTM that any SPI flash programmer should be able to read and write any chip with the standard pinout and basic command set by selecting a generic chip type and specifying the Vcc. The programmer should not just give up if the chip ID isn't in its list of supported devices.

[jol qwerr]

+1 to Frank

i read a lot of chips even if its not supported just by selecting a similar 1

as long as the V & size are the same

[pbzcbf...@gmail.com]

https://www.issi.com/WW/pdf/25WQ020-040.pdf

The absolute maximum rating for Vcc is -0.5V to + 4.0V.

[pbzcbf...@gmail.com]

Perhaps it might be worth comparing resistance measurements between a new chip and a dead chip. For example, measure the resistance between each pin and ground, and between each pin and Vcc, and between Vcc and ground.

[pbzcbf...@gmail.com]

Perhaps you could ask here:

https://forum.reveltronics.com/viewforum.php?f=22

It appears that there are 4 x 20-pin buffer chips (SN74CB3Q3245PW) which can be damaged by misapplication of an external supply, for example. The programmer has a user-invoked self-test which tests these buffers.

This thread may be of interest:

https://forum.reveltronics.com/viewtopic.php?f=22&t=445

The user seems to be saying that other USB devices were interfering with the programmer, possibly due to their current draw.

[pbzcbf...@gmail.com]

More thinking ...

The ZIF socket has 32-pins. Those "buffer" chips are actually bidirectional analogue switches. Four chips at 8 switches per chip means that the 32-pin ZIF socket is totally controlled via those switches. This includes data pins and power pins. My old Sunshine Expro-60 programmer had a 40-pin ZIF socket which was similarly controlled. None of the switches were activated (ie all were open) until the user accessed the chip via the software. I would think that the Revelprog IS would also power up with all switches open ... unless it was faulty.

https://www.ti.com/lit/ds/symlink/sn74cb3q3245.pdf

[Mike - USBRecovery.co.uk]

Im using the SOC-8 zif built into the unit.  The self checks all pass and I used it to write the client ROM back another ROM yesterday. I closed everything down, put the chip in, reconnected and then reopened the software, ID'd the chip and wrote without issue. 

I seem to be spending most of my time lately trying to get tools to work rather than using them, I don't have enough of a need to drop yet another 200 quid on a RT809 but I really would like something I could have some confidence in.  Still waiting for my AE order to be delivered before I dig deeper. 

[pbzcbf...@gmail.com]

I still find it hard to accept that the socket could be live immediately after power-up. It should only be powered when the BSY LED is on. At least that was the case with my old Expro-60. The resistance measurements I alluded to earlier could possibly shed some light on the failure mode.

[Mike - USBRecovery.co.uk]

I don't think it's live on power up - just ignoring the voltage settings in the software. I couldn't find anything odd in the resistance between the 'bricked' and my working ROM. I've tested my theory this evening an nothing higher than 1.8v was output regardless of plugging in and out and whatever procedure or routine. So that was wrong.

I then tried the main socket with a solder adapter and all 4 of the chips I thought were bricked could ID and be read. Tried them back in the ZIF, 3 of 4 dead, but 1 worked. That leaves me thinking either there's an intermittent fault on the SOC-8 ZIF or the legs have to be so clean as to not be practical. I did a quick check by cleaned them with wick and IPA and everything appears to be making a connection but still nothing from the 3. 

I want to check again tomorrow to make sure I can still read all 4 after soldering again. 

[pbzcbf...@gmail.com]

Interesting. I wonder if the socket is wired in parallel with the uppermost 8 pins of the 32-pin ZIF. If not, then it must be using different buffers/switches. You may need to open the unit and have a look, or you could perform a continuity test between the SOIC-8 and ZIF-32 pins.

[Mike - USBRecovery.co.uk]

Given the really low difference in resistance between all 3 connection methods (0.1ohm) I'd say they're all in parallel. The new chips arrived today,  and as these are untouched by my mucky soldering I'll see if I get consistent readings from the zif. Hopefully I do and this can all be put down to less than spotless chips, I can just switch to a pogo pin adapter and avoid the frustration in future.

You might want to think about investing in the MRT Equalizer PCBs (can be used with PC3K). You can read the ROM direct through the MRT board, unlock it in MRT or PC3K and write it back without removing the ROM or PCB.

IMHO, this Reset hack will improve the functionality of these "equalizers". In fact, the hack may render the SATA "equalisation" unnecessary.

I've had these in my wish list for a while and I've just placed the order for a few. Tim's post convinced me.

From what I can see from images and reading the spec, it's a USB to Serial connection via a CH343 chip https://www.waveshare.com/wiki/CH343_USB_UART_Board that allows direct read / write of the rom using software that MRT have bundled..  

My POGO reader is often needing 5 attempts to read now, and this should make things a lot easier.

I would say in principle it is but just a different factory and design.

I have very bad luck or never had any joy with the dolphin HDD tools clip on boards.  I would rather solder wires and remove caps than go through the trauma of getting one to work without having to constantly apply manual pressure at various points on the PCB.

Looking forward to getting the MRT ones that quite a few people now are using and have reported to be good and they seem to be improving the design.  They look many times more sturdy than other adapters.

It should quickly allow checks without soldering and removing components which is a massive time saver.

There are different designs depending on the PCB, but here are front and back pics for the 800069. Most times you don’t have to remove the USB bridge caps, but on some PCBs they still cause interference. I remove mine off all PCB with hot tweezers (10 seconds). Nothing worse than having an WD SMR drive after a head swap that you have to shut down and reboot to remove them.

I did see the post a little while ago and was under the impression that you were suggesting to short the reset pin to ground? Is that correct (at least that was the way I read it at the time, but the whole post may not have been completed then). Removing caps or shorting the reset pin takes pretty much the same length of time to complete so I never used it. But are you suggesting trying it so MRT can add another pin to the Equalizer PCBs?

Yes, that would a useful addition. You can attach an SPST toggle switch to the PCB via two wires. The length is not critical, as this is a DC signal. Doing it this way is non-invasive and it would be a far more elegant way to keep the bridge quiet, assuming there are no unforeseen complications. It would also obviate the necessity to reinstall those coupling capacitors should the need arise.

I'm assuming that the ROM is accessed directly via its pins rather than via the MCU, in which case locating the reset pin of the MCU may also help in certain circumstances. However, I can't help with that.
