USB Audio DFU Topic is solved

[ilkerxlm]

Hello,

I'm following AN02019: Using Device Firmware Upgrade (DFU) in USB Audio guideline. Using xmosdfu on Ubuntu and xu316 on custom hardware.
when trying to flash (note:VendorID is set to 0xbeef) :

Code: Select all

./xmosdfu 0xbeef:0x0016,0xbeef:0xd016 --download ../../app/bin/upgrade/upgrade.bin

I get:

Code: Select all

runtime vid 0xbeef, pid 0x0016. DFU vid 0xbeef, pid 0xd016
Found Runtime: [beef:0016] ver=1000
Opening DFU capable USB device, [beef:0016], Runtime mode.
XMOS DFU application started - Interface 2 claimed
Detaching device from application mode.
error detaching

I did set udev rules so I can access the USB device with full permision. However it still fails. Any ideas what it could be?

Thanks...

What command did you use to originally flash the device?

Hi Ross,
I used:

Code: Select all

xflash --factory ../bin/factory/app_factory.xe

When I use:

Code: Select all

./xmosdfu --listdevices

I get:

Code: Select all

Found Runtime: [beef:0016] ver=1000

Since I was compiling with:

Code: Select all

#define EXCLUDE_USB_AUDIO_MAIN

I was missing DFU logic in my main.c . After this modification it works as expected. Thanks.
