restore CF qnx system from windows?

QNX DEVELOPERS General Programming

I have created my qnx system in CF card,but sometimes the cf can’t work,it can boot but some dir lost,now I want to restore it under windows,
Is it impossible?because usually the cf card reader only can work under windows,but the windows can recognize qnx file system,how to do?

2

Windows doesn’t understand qnx filesystem.

3

Have somebody done the same work before?Is it possibel using ghost or other tools?

I need write the data of cf(qnx) to one new cf card,the problem is:
1)in qnx(or under vmware)can’t recognize cf card reader(usb)
2)in windows it can recognize cf card reader,but can’t understand qnx filesystem

The USB CF card reader should work under QNX - at least, I have one that does.
As a test you could try to mount an USB memory stick.

My configuration: QNX 6.3.2 installation in a VMware (version 5.5.2) container with an USB CF card reader.
I had to add the option uhci.newCore = “FALSE” at the *.vmx configuration file of VMware.

“I had to add the option uhci.newCore = “FALSE” at the *.vmx configuration file of VMware”
where can I change?

I do just as you said,add the “uhci.newCore = “FALSE”” at the .vmx configuration file of VMware,but when I log in qnx,it can’t find the cf card in /dev as hdt79,why?My qnx is 6.3.2 and the VMvare(5.5.3)

xuyong,

I don’t know if the “uhci.newCore = “FALSE”” option is necessary or helpfull for VMware 5.5.3. I can only speak for 5.5.2. There is a VMware project at the QNX website - maybe somebody can help you there with this: community.qnx.com/sf/projects/vmware

But check this first:

  • did you add a USB controller to your VMware container?
  • can you select your device from the VMware menu “VM->Removable Devices->USB Devices”?
  • is the USB server started on QNX? (check with the usb utility, look for /dev/io-usb/…)

Yes,you are right ,thank you

We are you using CF card readers with the following versions:

VMware 5.x works without changes
VMware > 5.5.3 uhci.newCore = "FALSE
VMware 6 (latest) updated io-usb + devu-ehci.so + devu-uhci.so from community.qnx.com/sf/projects/vmware

@fiffi

my VMware is version 5.5.2 build-29772. I just did a test and it doesn’t work WITHOUT the uhci.newCore = “FALSE” option.
