I bought a usbASP programmer from eBay and every Nano I tried to burn a new bootloader, the Nano died. I have a small pile of them now. No more heartbeat when powered on.
Attempts to burn others with Arduino as ISP always failed but i suppose thats another topic.
I bought new 328's to fix them, assuming the usbASP had blown them, replaced the chips but still no heartbeat.
I was under the impression that the ATMEGA chips produce a short heartbeat on startup regardless of whether a bootloader is installed.
Is this correct?
Since I dont have a working method of burning bootloaders yet i cannot test the 'repaired' Nano
Also, do you think the programmer actually blew the chips or just corrupted them?
