imxrt1064 DFU examples - do they work?

tamir_michael — Thu, 09 Jan 2020 12:14:33 GMT

Hello,

I have tried all the DFU samples for imxrt1064 (evkmimxrt1064_dev_dfu....bm, freertos) but the MCU does not provide its memory layout to the host - at least, that is what dfu-util reports:

dfuIDLE, continuing
DFU mode device DFU version 0101
Device returned transfer size 512
dfu-util: Could not read name, sscanf returned 0
dfu-util: Failed to parse memory layout

But the DFU device is indeed detected:

Found DFU: [1fc9:00a1] ver=0101, devnum=16, cfg=1, intf=0, path="1-4", alt=0, name="DFU DEVICE", serial="UNKNOWN"

by "dfu-util -l".

Any comment will be greatly appreciated!

Hi Tamir,

I tested this example on myRT1064-evb board. It works find.

Did you change anything in example source code?

Jing

Hi and thanks for your reply,

Absolutely not. I use SDK v2.6.1 - maybe that's related to what's happening...?

I do use a more recent version of dfu-util, though (see above).

Hi,

The most update version is 2.7. You can take a try. But all the example has bee testes well. I thinks that's may not the problem.

There is many other USB example. You can try other example to see if there is other problem on board.

When I execute "dfu-util --version", I see:

dfu-util 0.9

Could you update your tool and test again?

I cannot update my SDK - see this thread...

Hi,

I checked SDK2.6. It also can work. Are you sure there is no hardware problem?

Absolutely. I was wondering if it still works with the latest dfu-utils...

Hi,

I use dfu-util-0.9-win64.zip. Can you try it?

Hi,

I don't know what happened, but it seems to work now. Maybe I changed something unwittingly...
