uTasker 1.4 Unknown USB device

[ing_albertopc]

Hi !

I'm using the uTasker 1.4 for kinetis on a custom board. I followed the steps on this post uTasker Bootloader Porting Guide ,I loaded the bin file and the board goes on bootloader mode but when i connect the USB to a computer it says Unknown device.

I'm using a MK53DN512 and a TWR-K53N512 configuration.

Is this a problem with the driver?

How can i solve this?

I'll be thanckful for your help.

Regards.

Finally i solved it, was a problem with the USB clock.

Now when i try to send the file, the bootloader answer  "BAD FORMAT", I followed the steps on this post How to create .s19 file from project settings to get the s19 file from the application proyect.

I'll be thankful for your help.

Hi

I have just seen this - 3 years too late.

If it has been posted in the Kinetis forum I would have answered immediately. Sorry...

If you don't get an answer here I'd suggest you look on the uTasker site.

Read documents like this one (that detail the driver you have to install on your PC to get this to work) or read the Forums there:
