Hi
I am from China. Now I have a problem. I have three firmwares used for USB Audio。The XMOS is XU208. I've done all the work。 I know use the "loader.xc" to select which firmware to work. The boar working is OK. Now how can I use the "DFU" to upgrade the three firmwares. I have try like the following：
xflash --factory-version 14.1 --upgrade 0 app1.xe --upgrade 1 app2.xe --upgrade 2 app3.xe -o dfu.bin --target-file app.xn
Yes, It can generate "dfu.bin". It also can upgrade. But the board is not working properly. Not correctly loaded corresponding firmware。If I use the JTAG to flash the board, it can work OK.
So the command used for DFU is wrong？？

(mod edit: updated thread title to reflect question)
You should use a command like the following to program the board:
xflash app1.xe --upgrade 1 app2.xe --upgrade 2 app3.xe
And a command with the -o option to generate the for DFU.. e.g..
xflash --factory-version 14.1 --upgrade 1 dfu_image.xe -o new_firmware.bin
What image are you trying to upgrade, all of them?
