Checksum Error

New MessageChecksum Error (modified 0 times) bubbleshack

I've been trying for several days to update my Audrey via CF. Using a Windows XP box with a Sandisk SDDR-31 reader and a Memorex 32 MB CF card & a SimpleTech 128 MB card. Regardless of what image I use, or which method I utilize to transfer the image onto the card (Hex Toolbox, ntrw, etc.), the Audrey loads for about 30-40 seconds and then reports a Checksum error.

WinHex reports the following information on the card:
Note: I've used both numbers with mkcf for card size.

Free Space: 32,669,696
Total Capacity: 32,751,616

Bytes per cluster: 2,048
Free clusters: 15,952
Total clusters: 15,952

Bytes per sector: 512
Usable sectors: 63,808
First data sector: 159

Thanks in advance, and if anyone gets this to work for me, I'll send you this 32mb CF card because I'm tired of looking at it. Let me know either via the bb or through mail at nhoyne at hotmail.com

I don't know why nobody responded to this message, but I had exactly the same issue and had to hunt through a million and one threads to find something that worked. And my frustration level was through the roof!

First off, NTRW did NOT work for me. It gave me varied results with the BEST result being the checksum error you mentioned.

As soon as I switched to GemXplor w/ a cheapo (Memorex brand, but most others should work) USB CF reader. That worked first time. No more checksum errors.

And I loaded the latest/greatest Jukebox w/ USB support so I could finally get my stupid Pegasus-based USB NIC working! (Here's hoping it does!)

Happy imaging to all!

P.S. For those too lazy to search for it, download the GemXplor tool here:

LauFu,
Please let me know if your pegasus based nic works ok? I don't have one and haven't been able to test it myself, but it should work.

LauFu,
What I especially need to know is how busy your CPU is in Audrey with this pegasus nic hooked up and if you notice changes in the screen handling compared to previous images without this new USB support.

Well, so far, no luck on the Pegasus. I'm using a D-Link DSB-650 (translucent i.e. rebranded) I'm still plugging away. I have been trying to run the drivers manually as well, but to no avail. (Said that it couldn't load the ppp dll or the qnet. I tried loading without those too and it CLAIMS to load, but I don't even see a light on my USB adapter.

Thoughts?

And CallerID isn't working for me in the USB image. At least not from shelf.

(FYI, in case you hadn't noticed, I'm new to QNX/Audrey hacking. But I love it!)

***** I also want to make an IMPORTANT CORRECTION to my earlier statement... Apparently I got lucky the first time writing the wrong size of image using Gem. I used Gem to save the contents of the CF card to a file and then used that file size with ntrw.exe. That also appears to work. For some reason, even Linux has misrepresented the size.

For those keeping score at home.. (from Windows)

1) Download gem (link above).
2) Run it w/ your CF card in a USB adapter.
3) Select the SCSI device for your adapter. (mine is a "(USBAT Compact Flash )")
4) File|Create Image from Physical Disk and give it a name
5) Use this filesize of the created file as the size parameter for mkcf (mkcf jukebox.usb1 audrey.flash <size>)
6) ntrw write audrey.flash f: (change f: do your drive letter)
7) Power-up Audrey with the card in place and the datebook button depressed. (not suicidal, just depressed)
8) If it doesn't bitch about invalid images or checksums and finally boots to a new image, repeat 7 but press both datebook and power buttons.

And to the developer of NTRW, I'm sorry I ever doubted you.

LauFu,
Wish I had one of those adapters here.. Anyhow, the net modules have to load in a specific order and if they don't it will not work. In /nto/bin/networkUSB.sh is a sleep command and maybe your nic needs more time to come alive. Change it in sleep 30 and check if that works. Don't forget after the change to press "USB Connect" in shelf/Config before you reboot to have the changes take effect.
After rebooting wait at least 30 seconds after the boot is completed before you touch anything. If it works you can figure out how short the sleep could be for a proper load.
If it still doesn't work run the /nto/bin/networkUSB.sh script from the prompt and it will tell you exactly what the problem is.
BTW, do you have a klsi based card too and is that one working with the proper script? Mine stays up for days in a row, so I see no reason why the pegasus nic couldn't do the same, unless if I forgot a lib for that card, but running the script in terminal will tell you so. Disable -pqnet while testing.

LauFu,
And is your router setup for dhcp? The current script expects that or you have to change it for a fixed address.
One step at a time.

Will try after dinner or tomorrow and follow-up. Thanks for the help.

If it comes down to it, I may have to send you one of these things. (CircuitCity had them on sale for $15/apiece, so I bought 3. Hope I don't have return them.)
