avrdude.exe: verification error; content mismatch

[Jithin]

Hi,
I’ve (actually my dad, I set it up for him) been using opensprinkler v2.2 (bought fully assembled) for over a year without issues. A month back, he complained that it was no longer working – the HTTP connections used to hang. I tried to reset it, but no luck.

I saw that a new firmware was out and decided to flash it. I downloaded the updater and tried updating the FW. It says
verification error, first mismatch at byte 0x0000
0x0c != 0x62
verification error; content mismatch

Full log attached. Any pointers is appreciated. 🙂

OS: Win 10

There may have been some sort of flash memory corruption. Can you submit a support ticket? We probably need to reflash the microcontroller (not through the USB port, but through the ISP pin headers).

Ray,
Sure, I will submit a support ticket as soon as I am home (in another 8 hours). I am in India, so should I be buying a USBASP or USBTiny in anticipation?

Regards, Jithin

Ray, the device is now in India. Its gonna take a fair amount of time and money to ship it back to you.

I opened it up today and i think the ISP headers under the LCD, right? Please send me the instructions and I’ll try to do it myself.

Regards, Jithin

OK, will follow up on the support ticket.
