Quick questions:

My scope doesn't display any S/N in the information menu. Is that so because the nvram contents may be corrupted?
I've found a .sn and .key file inside the vxboot... are these supposed to be flashed into the nvram once I clear it?

Hi

I've recently acquired a TDS7054 with no hard drive and a flat battery on the PC motherboard.

I have replaced the battery and installed Windows XP on a new hard drive with maximum FAT32 partition size of 32GB and updated all of the drivers using DriverMax.

I have installed the latest Tektronix firmware 2.5.3 for this model and now just get the TekScope Splash screen.

Connecting up a serial terminal to the PPC console port I have setup the standard boot parameters but it stops booting after the following lines. It doesn't seem to get to the part where it loads the boot files.

Code: [Select]
Initializing backplane net with anchor at 0x1e80000... done.
Backplane anchor at 0x1e80000... Attaching network interface sm0... done

Could this be an issue with Windows XP or the hard drive formatted using FAT32 ??

cheers

Going from memory here...
I think 2.5.3 is for the 7154 or higher bandwidth scopes. Latest for the 7054/7104 is 2.5.5

I know that 2.5.5 won't work right on the 7154 and higher scopes, but I don't know if the reverse is true.

Also, try re-seating the connectors between the NLX motherboard and the PPC board.

Lastly, check device manager and be sure that all the devices have installed correctly other than the PCMCIA and the ATI graphics chip that don't work in these scopes when running XP.

Yes it's in c:\vxBoot

When specifying the directories in the boot parameters do you use forward or back slashes ??

Also I could not find dio_rst.vsh on the HD so I just used topScript.hw which is what they used here https://forum.tek.com/viewtopic.php?f=568&t=136976&p=279248&hilit=vxBoot#p279248

Sorry I did use firmware 2.5.5 for the 7054 ;)

I took a screen shot of the Device Manager. When I checked the PPC battery I did spray the connectors on the riser board and PPC board but I will check the other connector on the PC motherboard.

cheers

What is that PCI Bridge without the driver? If that's PPC board, then it cannot talk to PC PCI side and get it's desired RTOS stuff from vxBoot.  :-BROKE

It uses an Intel BL440ZX motherboard and the only official drivers I could find are here which doesn't appear to include the PCI bridge drivers

https://downloadcenter.intel.com/product/50298/Intel-Desktop-Board-BL440ZX

I did not use any of these drivers because I let DriverMax do it stuff.

According to the manual the chipset used is:-

Chipset Intel® 82440ZX AGPset (on the 66-Mhz host bus), consisting of:
·  Intel® 82443ZX PCI/AGP controller (PAC)
·  Intel® 82371EB PCI/ISA IDE Xcelerator (PIIX4E)

Drivermax will never find drivers for the Tektronix specific hardware like the front panel, ACQ controller, and the Asilent/CHIPs video controller. I can help you in a few hours... Stand by.

Thanks Jay, I will give it a go tomorrow ;) Also did yours come with a program called CMOS.exe used to program NVRAM on the NLX board ? I'd like to get rid of that annoying network search when the thing boots up. I found some description of it here.

Hello,

I got a few time ago a defective TDS7054 and I'm trying to repair it.
Thanks to this forum and especially this thread, I was able to perform several tests and corrective actions. Unfortunately without success.

The problem: Windows 98SE boots normally but the instrument hangs on the TekScope Splash screen.

What I have done :
- Update to firmware V2.5.5 -> no change
- Quick internal visual examination -> no trace of damage
- PPC 7 segments LED indicates normal booting sequence up to the blinking (-)
- Connexion of console port to an old laptop (fitted with COM port) -> boot listings below
- Checking of PPC NVRAM battery (PowerCap) -> dead, 0.29V. Connexion of a fresh CR2032 battery to the PowerCap with external wiring
- Attempt tu restore boot parameters from console (no need, parameters seemed correct, see below)
- PPC booting with the file executing : tcsLoadTableToNVRAM "setup.tcs". This file is named tcsTopScript.vsh in my VxBoot folder -> TekScope still hangs
- Editing of topScript.hw in order to execute "NvramClearDb = 1", then rebooting with topScript.hw restored in initial state -> no change
- Checking of the NLX board CMOS battery -> OK, 3V. Anyway, initialization of the BIOS parameters with the MSDOS command CMOS -r nonet -> no change
- Cleaning of edge connectors NLX board to riser board, and riser board to PPC board -> no change
- Checking of power supply voltages (service manual page 6.56) : all correct well within tolerances except fan voltage (should be 9.8V, measured 13.2V). I suppose fan voltage is not critical and not the source of TekScope anomaly.
- External VGA monitor connected to NLX SVGA port : displays a text saying Windows initialized the display adapter (see below).
- External VGA monitor connected to PPC VGA port : same image as flat panel.

Remarks :
- At the end of the PPC booting sequence, I can hear relays clicking, I suppose on the acquisition board.
- After power off, the NVRAM drains abnormal current from the battery : I measured varying current between 0.5 to 2mA ! However, the NVRAM test during POST does not fail.

After all this I am a little desperate |O. Does someone have an idea ?

Thank you for reading,
Pascal

Replace the nvram - they are famous for dying, replacing the battery is rarely enough.

Even if the NVRAM test pass during the POST ?

Yes, I had same issue, NVRAMs data bit was stuck low. Replacement fixed that. Maxim still has replacements in this package.

Agree with Steve and TiN. I've seen a number of these that draw too much current.
Also, these are worrying:
...
tcsSynchronize: ERROR: DAC synch failed

AND
...
Exception current instruction address: 0x00223e50

It looks like something is crashing. Try re-seating the DIMM on the PPC board. If you have a known good DIMM, try that as well. Also, if you put the PPC DIMM into the NLX motherboard, you can run memtest86+ on it.

I have got a bit further with the driver installs ;) Now still some conflict with the display driver. (see the screen grab below)

But the thing boots into Vxworks and I can hear some of the relays click over but hangs a bit of the way through it. I was wondering what startup script are you using ?

Forget the ATI video under XP, you need to install the Asilent video driver which I posted above.
But I don't think the video driver is the problem...

Do you want me to post the two scripts in the image I saved off?

Hello Jwalling,

PPC and NLX boards use exactly the same model of 128Mb DRAM.

I first ran Memtest86+ on the NLX DRAM -> no error
Then I swapped DRAMs between NLX and PPC and ran Memtest again -> no error

Then I restarted normally the oscilloscope (with DRAMs still swapped) -> no change, same tcsSynchronize ERROR and exception, and Tekscope freeze as before.

Can't think of anything else to try except checking the interconnect boards for bent pins. Still, you have a questionable NVRAM in there; I would consider replacing it before going any further. I remember seeing one that would pass the PPC diagnostics, yet fail the scopes diagnostics after the application loaded.

Put these in the root folder of the scopes hard drive.

I have got a bit further with the driver installs ;) Now still some conflict with the display driver. (see the screen grab below)

But the thing boots into Vxworks and I can hear some of the relays click over but hangs a bit of the way through it. I was wondering what startup script are you using ?

Forget the ATI video under XP, you need to install the Asilent video driver which I posted above.
But I don't think the video driver is the problem...

Do you want me to post the two scripts in the image I saved off?

Yes please do. I am using active file compare to compare the console outputs.

I did noticed the follwing descrepancies comparing with TiN's console output.

This is from my scope:-

Code: [Select]
tcsTableUnpack: checksum failed on buffer
tcsTableLoadFromNVRAM: tcsTableUnpack failed

And this is from TiN's scope:-

Code: [Select]
usrNvFsInit: NAME=/nvram BASE=0xfd0ff100 BPB=512 BPT=8 NB=8 BO=0
nvfs: STATUS: Mounting existing NVRAM file system

I do notice that Windows XP has trouble with the Asilant video driver. It says it cannot load the drivers so is just defaulting to the standard VGA driver.

It's possible that this thing cannot work under XP.

I may try another build using Windows 98.

Regards
David

It should be able to work under XP. I've done it myself. Let me check again though my images.
Here's the two files.
