Trying to rescue 32 TQFP mounted on PCB
Posted: Fri Sep 26, 2014 9:10 am
Hi, I bought the rescue shield to rescue a couple of MiniWireless-HW (http://www.anarduino.com/miniwireless/) but I'm not having much success
I have tried both the original arduino sketch and the alternate firmware by Dennis but both fail (differently).
With the original firmware I select atmega and then connect the shield to my PCB. But then I am supposed to enter the fuses I want but when I press send to set the first (low) fuse value nothing happens in the serial terminal. I also tried to disable the interactive mode and then pressing the GO!-button. The burn LED blinks and the ready LED comes on again but the circuit on the PCB is still inaccessible to my AVR-ISP-MK2 from AVR Studio so the fuses are still broken.
The alternate firmware prompts me for the device and when I select to burn fuses it spurts out some random chars and selects something else like erase flash or read flash.
The (simple) schematic for the MiniWireless is available here: http://www.anarduino.com/miniwireless/m ... ss-sch.jpg
Please advise..
Thanks,
