USB MSD with MQX3.8

[t_k]

I'm new to using MQX and I could use some help.   I can't seem to be able to get the msd example included in mxq 3.8 to work.  It appears to enumerate fine, and brings up the prompt to format the drive, but formatting fails everytime, plus it is very slow. it also doesn't show the proper size of 30kb, instead it says unknown capacity.   I'm using the TWR-MCF54418 to run this on.

As a background test, I tried using the msd example from version 3.7 and it worked perfectly.

My guess is that I have simply overlooked a simple #define somewhere, and I would appreciate it if someone could point me in the right direction.

thanks,

Travis

Hello,

Can anyone else using the TWR-MCF54418 along with MQX 3.8 please verify if the USB MSD Device demo works?

I'm on a tight timeline and I can't seem to figure out what I'm missing.

Thanks,

Travis

Hi Travis,

I tested the USB Host side succesully using the following:

C:\Freescale\Freescale MQX 3.8\mfs\examples\mfs_usb\cw10\mfs_usb_twrmcf54418

When trying the USB MSD device I've failed so far so will dig further.  I have old TWR-SER2 card so maybe that is my problem.

Hi David,

any luck?

We're trying to develop a custom board, and I ended up getting it to the exact same place running the demo as I was with the TWR-MCF54418.

any updates on when MQX version 4.0 is coming out?   I'm hoping that it may solve my problems.

thanks,

Travis

Hi Travis,

The MQX4.0 should be posted to the web this weekend.

I have beta version and just tested successfully both MSD device and host.

Hi David,

Has MQX4.0 been delayed?   I haven't been able to find it on the web yet, and we're fairly anxious to try it and see if we can solve some of our USB and SDcard issues.

thanks,

Travis

Hi Travis,

Santa's sleigh having issues :-)

Sorry.

We did release internally and now are waiting for our web/IT people to post.  They indicated on or before Friday the 14th.

My apologizes for incorrect date to post.

Hi David,

I understand.  We have some of the same problems here.

Thanks for the update,

Travis

Thank you.

I need to read the roadmap for 4.0 over again to see what else has changed.

Thanks again,

Travis

I believe that's the setup that I have as well. 

Thanks, at least it isn't just me.

Looks like I'm going to have to change gears and try to implement a USB host plus communications.

Hopefully that makes it easier.

Hello Travis,

which example are you running? Host or device?

hello Martin,

I'm trying to run the device example.  All the other examples I've used for learning mqx have worked without a problem, so I'm not sure what I'm overlooking this time.

Thanks,

Travis
