flip2: ATxmega32A4U DFU bootloader does not work even though Atmel FLIP 3.47 works fine. #1082

mcuee · 2022-08-21T14:27:09Z

I have got the DFU bootloader to work on a simple breakout board of ATxmega32A4U (from MCUzone).

avrdude vs Microchip Studio for an xmega hex file #1075

When downloading application, Atmel FLIP 3.47 works fine. However avrdude does not seem to work.

PS C:\work\avr\avrdude_test\avrdude_bin> .\avrdude -c flip2 -p x32a4u -U application:w:flip2_demo_app.hex:i

After I program the demo application using Atmel FLIP 3.47, avrdude still failed to verify.

I wonder if this has anything to do with the ATxmega32A4U being a device with less than 128kiB flash.
I have a hybrid Arduino UNO board with an ATxmega128A3U I can modify to piggyback a USB connector on, so I can check if flip2 works or not on this chip.

I've had a look at Xmega-based Xplained boards, and very few of them have a "native" USB connector intended for the flip2 bootloader. I have an STK600 that could be used for this, but the socket adapters are so freaking expensive that I can't justify buying one just to help out and potentially fix a single issue.
EDIT: STK600 socket adapters are also going obsolete, so they're also difficult to find

@MCUdude

I am going through the existing bug reports and this is one of them. Just wondering if you have got a chance to test on your side. Thanks. But I think this is not an important one to fix.

Unfortunately I can not get the USB bootloader working now for this device. Strange. The device can not be recognized by Windows 11 or Ubuntu Linux 20.04.

Edit: the bootloader can be recognized. I need to press the S2 button (PE0 pin) to go into bootloader pin.

dmesg log under Ubuntu 20.04 Linux.

[  695.703304] usb 3-1: new full-speed USB device number 24 using xhci_hcd

But it does not work at all under Linux.
