Parsing error #8

Closed diogobenica closed 2 years ago

diogobenica commented 4 years ago

I was able to install a new effect but afterwards every time I try to connect do the Zoom G1X Four it raises this parsing error. I tried to factory reset and reinstall the latest firmware 2.0 but the error persists.

Traceback (most recent call last):
  File "zoomzt2-gui.py", line 148, in butConnect
    self.ConnectPedal()
  File "zoomzt2-gui.py", line 242, in ConnectPedal

construct.core.ConstError: Error in path (parsing) -> header
parsing expected b'\x01' but parsed b'\x00'

Did someone have the same problem?

Running with Python 3.8.3 and all the libs on latest version.

I looks like (for some reason) that the FLST_SEQ file stored on the pedal doesn't match what we are expecting.... I think the error is coming from this 'const' definition: https://github.com/mungewell/zoom-zt2/blob/master/zoomzt2.py#L19

Are you able to download a copy of FLST_SEQ, either via the 'Files' tab in the GUI or via the command line, so we can see what has happened? zoom_files

diogobenica commented 4 years ago

@mungewell Thanks for the response! Via GUI it didn't show anythiing in effects/files list. But via command line I extracted the file:

FLST_SEQ.ZT2.zip

diogobenica commented 4 years ago

@mungewell I changed the const definition you pointed out to b'\x00' and it worked. The GUI is showing the files and effects.

mungewell commented 4 years ago

Why good that you have a workaround, but 'we' should figure what that '0x01' or '0x00' means. It would be better to define the location as a 'Byte' so that it gets preserved at whatever it actually set...

I note that you had PDL_PIT.ZD2 installed at some point, do you have a G1FourX?

diogobenica commented 4 years ago

@mungewell Yes, I have the G1FourX (with expression pedal). Also, today I was trying to install some effects from G11 and after I got some effects working and some don't (I got a checksum error for some and for others it was installed but don't show in effect list) the byte changed back to b'\x01'! So I don't think is a hard-coded version related byte.

mungewell commented 4 years ago

If you change the 'const' definition to 'byte', it will be preserved at whatever value is read: "unknown" / Byte, # Bug 8

Regarding taking effects from 'better' pedals; we saw before the issue where effect wants to draw on 2 screens, the simpler versions for the G1Four (and friends) have a different name to reflect they only use 1.... I was also reported that some effects from the G5 would not work, assumption is that they need more processor/memory than the G1Four has. https://github.com/mungewell/zoom-zt2/issues/5

A while ago I crafted a list of effects from different devices. It might be nice to improve, and make this an automated process. https://github.com/Barsik-Barbosik/Zoom-Firmware-Editor/issues/12#issuecomment-523738661

Does anyone still keeps the firmware file B1Four version 1.10. I believe the file name is B1_FOUR_v1.10_Win_E.zip. I only have firmware version 2.00. I am confused that the B1Four firmware version 2.00 has the same effect as G1Four. Thanks. Sorry for my bad English.

Yes, I also noticed that the B1Four has the 'wrong' embedded FX. I have found a few older F/W via the Way Back Machine https://web.archive.org/web/*/zoom.jp

Thank you very much @mungewell for your fantastic work...

I finally found the firmware file B1Four version 1.10 although it is for Japanese Windows (B1 FOUR_v1.10_Win_J.zip) but it can be installed on my B1Four without any problems .. I also downloaded Firmware G1 FOUR_v1.10_Win_J and G1 FOUR_v1.10_Win_E.

Then I install firmware v1.10 (B1 FOUR_v1.10_Win_J.zip) into my B1Four. This is actually a downgrade process of my B1Four firmware, from version 2.00 to version 1.10. And it happens very smoothly and with the same procedure when upgrading the firmware. Nothing special.

After that, i try to removing some unused effects in B1 Four with Zoom GuitarLab to free up some space. But what happened is, Guitar Lab always tries to reinstall the deleted effects. So the best way is to remove effect with the zoom-zt2 application. I even only use zoomzt2-gui.exe to remove and install the * .ZD2 effect

And then the miracle happened.... Finally the effect *.ZD2 from G1Four, G3N, and G5N firmware can be installed and appears both on my B1Four LCD screen and in GuitarLab.... yeeeeaaahhh... ... I was really amazed...

I've tried several * .ZD2 guitar effects from G1Four, G3N and G5N to put in my B1Four. Of course after I removed some of the effects from B1Four:

Dynamic: N_GATE.ZD2 (G3N) RACKCOMP.ZD2 (G1Four)

Filter: GTGEQ71U.ZD2 (G1 Four)

Amps: ORG1201U.ZD2 (G1Four) RCTORG1U.ZD2 (G1Four) MS800_1U.ZD2 (G1Four) FD_TWR1U.ZD2 (G1Four)

Cabinets: ORG_4X12.ZD2 (G1Four) RCT4X12.ZD2 (G1Four) MS4X12.ZD2 (G1Four) HW4X12.ZD2 (G1Four) MK3_1X12.ZD2 (G3N)

Drive: MTLWRLD.ZD2 (G5N) GOLD_DRV.ZD2 (G1Four) REDCRUNC.ZD2 (G1Four)

Delay: PPDLY_3S.ZD2 (G1Four)

Reverb: HALL.ZD2 (G1Four)

All these guitar effects are still in my B1 Four now side by side with the bass effects. GuitarLab reports Used Memory = 99%.

Ahhh... apparently the secret is just to use firmware v1.10 or maybe lower version (v1.00) in my B1Four. Previously when my B1 Four firmware was still v2.00 I always failed to use injected * .ZD2 effect. Effect installed and injected successfully in my B1Four, but does not appear in the LCD menu and cannot be used

It seems that zoomcorp is asking us to upgrade to firmware version 2.00 to avoid this... LOL..

Is it okay if I want to share the link for the firmware here? I'm afraid it violates the terms on Github.

This is a display of my B1 Four's LCD and a view of the guitar effects in GuitarLab: Picture of my B1 Four's LCD screen Picture of my GuitarLab screen

Once again I want to say so many many thanks for your hard work and also for all the people who helped make the zoom-zt2 application.
