firmware upload worked 1st time now says not responding

Post by ac4ag »

I just built a kit from an approves supplier on ebay. I uploaded the firmware with my callsign and it worked. Now, however when I try to use avrdudess to upload the beta firmware: The radio clicks and, I get this

Code: Select all

avrdude.exe: stk500_recv(): programmer is not responding
avrdude.exe: stk500_getsync() attempt 1 of 10: not in sync: resp=0x88

avrdude.exe: AVR device initialized and ready to accept instructions

Reading | 
avrdude.exe: arduino_read_sig_bytes(): (a) protocol error, expect=0x10, resp=0xe0
avrdude.exe: error reading signature data for part "ATmega328P", rc=-3
avrdude.exe: error reading signature data, rc=-3
avrdude.exe: stk500_disable(): protocol error, expect=0x14, resp=0x00

avrdude.exe done.  Thank you.
I wonder, have I messed up the bootloader?

Hello OM,

are you sure it is a good short usb cable, not one only providing power without communication wires inside? Looks like no communication at all....
And think about the Firmware type: standard usb firmware update without bootloader or isp connector with bootloader included (select isp upload at the beta download page).

It is not necessary if you have a working bootloader, there you should use usb standard upload!
If you killed your bootloader you must use with isp upload....

I know it's a good cable, because it worked the first time I loaded the firmware with my callsign. Which was a few minutes before I tried the beta FW. Also, it is a brand new cable, and When I plug it in it shows up in the devices. Also using the same settings as I did the first time

Is there a problem with port speed?

I am using the same port speed settings as I did a few minutes before when it worked. So I don't see how

Beta firmware has different speed, it went from 38k to 115k…

Well, when I flashed it the first time from what it came with to add my callsign, I used 115200 and it worked. So are you saying I should try a lower rate?

I reflashed the bootloader, and was able to flash the new firmware just fine. Super weird.
