dbFsIoctl: invalid code 3

This error is not a concern. It exists in my 7104 too.

Thanks.

be careful   as post#815  i re-copy here

In my case the target nam had to be this name i mentioned, because TekScope would be buggy  or would not start

This is what works for me in the nvram content

boot device          : sm
processor number     : 0
host name            : host
file name            : c:\vxBoot\vxWorks.st
inet on ethernet (e) : 192.168.0.1:ffffff00
inet on backplane (b): 192.168.0.2:ffffff00
host inet (h)        : 192.168.0.1
gateway inet (g)     : 192.168.0.2
user (u)             : anonymous
ftp password (pw)    : anonymous
flags (f)            : 0x1000
target name (tn)     : tds7000 -----> i've been told to keep it like this, if not, TekScope doesn't save some  settings ??
startup script (s)   : c:\vxBoot\topscript.hw
other (o)            : 0x0

Still have doubts on the flags and other sections,

if i put something else in the flag like 0x1008, tekscope stalls
if i change other setting like 0x1000  TekScope starts but no traces of ch1 ch2 .....  cant recall what i put ...

The  dbFsIoctl: invalid code 3    error you have,  may come from the topScript.hw file

thread at : https://www.eevblog.com/forum/repair/boot-problem-on-tektronix-tds7404-scope/ 


it direct to lines like :   

cd "dbfs:c:/vxBoot"   

dbfs:c:/vxBoot

Thank-you. I am getting there!
I did check for LF and CR but had only LF in my c:\vxBoot\topscript.hw but still get the error:
 dbFsIoctl: invalid code 3

Code: [Select]

    ################### topScript starts ###############################

 
 

     cd "dbfs:c:/vxBoot"

   
    ld < TekScope.o
    ld < TekScopeSM.o

    pDbDev = ramDevCreate(0, 512, 1152, 1152, 0)
    pDBfs  = dosFsMkfs("/db", pDbDev)
    copy ("TekScope.DBF", "/db/TekScope.DBF")
   
    overrideFPdefaults()

    measurePPCtimebase


etc...

As for the contents of topScript.hw, there is no command before "topScript starts", so it seems to be an error occurring before topScript.hw.
I don't think you need to worry about it. Doesn't anyone else get this error?

Which software do you use to connect the tektronic CSA7404? I use "tera term" software or Terminal software to connect TDS7104 but not useful. Please , Tell me . Thanks

[mda]

I used Putty but found out that it corrupted the data I put in, so I have used Teraterm with a god result.
Regards

Terraterm    Termite  Hyper-Terminal, Multi terminal 1.0.2 (you have to create some profiles in it)

Termite in my case,  but you have to enter the command  in the white bottom box / bar of the software (somewhat irritating)

Putty is a more advanced software, i'm not used to it


Normally  with no errors,   you have the final message in VxWorks    Running at  xxxx ticks  etc .....

Do i use a rs232-ttl converter and connect pin 11, pin 12, pin 15 of IC max232 on board PPC, right?

[squadchannel]

Of course it is possible, but you can also use the serial port of an Arduino or other microcontroller board.

[charlyd]

the TDS7054 is a different board series

[charlyd]

just of testing purpose :
does anybody know if i can test a TDS6104 ACQ board in a TDS7000 chassis?  i mean are the connector the same.  i want to check some working trigger chips before moving the to a 7000 board.
