Firmware update on k64 using USB?

[priyankb]

Hello,

I am using a custom board based on K64F and want to use USB(later OTG) for firmware update. We have done the USB MSD host. But now I am confused as to what device class should I use for firmware update part. We also have a PC software for firmware updation we used in coldfire. So I am looking for a short and quick way to implement this.

Any suggestions will be appreciated.

Thank you.

There are various (USB) loaders for your processor in the uTasker project.

hi Mark,

I tried an example from the Freescale USB stack but got error 43. So either my initialization is wrong or hardware is wrong.

Can you tell me if USB initialization functions in the stack are right or not?

Thanks

Priyank.

Hi,

Please let me know if I am understanding is correct or not. Did you mean that firmware update PC software as you mentioned for ColdFire? Or just the firmware updating process/way?
