Facing problems in uploading bootloader to Atmega128A #21

shaktidhar · 2016-09-25T04:47:13Z

{{ I already opened a thread at https://forum.arduino.cc/index.php?topic=425844.0 but then realized this might be the better place... }}

Hi,
I followed the exact circuit as noted https://camo.githubusercontent.com/b6046ccf5b261d6accdf030c2158ddb119f898d8/687474703a2f2f692e696d6775722e636f6d2f5549696e6f38492e706e67

But I get errors (or simply time out) while uploading.
I tried uploading the bootloader using a genuine Arduino Uno as SPI programmer. And just to experiment, I tried uploading bootloader using a USB to TTL serial connection.

No luck so far.

Is there any specific programmer that is known to work? There are conflicting notes on USBTiny. Seems it is better than USBasp but only works for Atmega64... Or I am just reading too much and not putting things in correct order?

Any inputs will be greatly appreciated.

Thanks.

I have no issues burning bootloader using the latest Arduino IDE 1.6.12, so it's not a bug in the core. I need to see a picture of your actual setup to be able to figure out what might be wrong.

You also need to turn on verbose output to get the full error information. Open Arduino IDE, goto settings and turn on all verbose option. Then post the error message from avrdude when you're burning the bootloader

shaktidhar · 2016-09-25T11:24:10Z

I am using the basic circuit :
https://camo.githubusercontent.com/b6046ccf5b261d6accdf030c2158ddb119f898d8/687474703a2f2f692e696d6775722e636f6d2f5549696e6f38492e706e67

I am sure there is no bug in the core, but apparently I should be using the correct programmer. Using an Arduino is not working for me. What else could I try to make it work?
This is the output when uploading :

I don't have very good experience with the Arduino as ISP programmer, and prefer to use the USBtinyISP, which always works. It seems like an issue with your programmer, so you should try another programmer.

The reason why I'm asking for a picture of your sets is because people tends to screw up without even knowing. It's impossible for me to spot HW errors without a picture

shaktidhar · 2016-09-25T11:39:03Z

I don't have USBtinyISP at hand. I read two different notes on it (one that suggested this works more reliably compared to Usbasp, and other that said USBTinyISP has been tested only for Atmega64 ). So, I didn't get one.
I will order one now and will update on the progress.

I will upload a hardware picture too. My soldering skills are a little embarrassing so showing off is not my instinctive action. I have a little suspicion on the crystal as well so will try replacing it and see if that can help.

MCUdude · 2016-09-25T11:40:58Z

You may try to burn the bootloader with the 1 MHz internal oscillator instead. If there's an issue with the crystal, that should solve it. If you want to change the clock frequency back to 16 MHz again, you just re-burn the bootloader

I guess that leaves me with no other choice but get UsbTinyISP.

MCUdude · 2016-09-25T11:48:58Z

There's a forum post discussing the exact problem with Arduino as ISP as you have:
https://forum.arduino.cc/index.php?topic=354674.0

If you're using an Arduino UNO; have you connected a 10 uF capacitor between the reset pin and ground (on the UNO)?

shaktidhar · 2016-09-25T12:07:33Z

Thanks.
Tried with capacitor connected.
Can't see any difference.

USBTinyISP ordered.

One query. The led on the circuit, connected to pin 15, is it supposed to be on when connected? (Mine is not, I am trying to rule out any of my typical mistakes.)

MCUdude · 2016-09-25T12:10:05Z

The LED is connected to pin PB5, and it should flash twice every second after the bootloader have been burnt. It isn't strictly necessary, but I've added it to the minimal setup schematic to help users debug potensial issues like this

shaktidhar · 2016-09-25T12:11:23Z

:-) Ok.
That means till the bootloader is up, I can presume it's ok that it doesn't blink...

yo8tww · 2017-02-09T09:04:52Z

Hi..I have the same issue with the USBtinyISP v3.0 I had just bought...I can't burn the bootloader on 128A. With another programmer ( AVRISP-MKII) and Arduino IDE 1.06 and chip-45 bootloader, it works but with higher IDE versions, with Mega core I can't burn it...
I have this error :

avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check

The same error appears when I'm using the Pololu USBavrISP v3, with only this 128-64 core. The rest of the avr's I can burn them whitout a problem..

Hi..just discovered another thing....The Atmega that don't initialize it's an Atmega128A AU...This can be written only with avrispmkII. Why ? I don't know...On an other board I have two avr chips, Atmega128 16AU
which can be bootloaded, programmed very well with the USBtinyISP...Weird, isn't it ?

yo8tww · 2017-02-11T06:41:40Z

Hi again..Well, it seems that usbtiny is very sensitive to loads on the PE0,PE1 pins and the avrispmkII seems to be more "tanky".Put a 1k resistor in series with PE0, solved the problem with avr device initialisation..Everything work fine now, despite those "content mismatch" & "programmer unsuported" messages. Thanks Hans for all this core...

shaktidhar · 2017-02-11T12:48:33Z

Ok, so I also added the 1K resistor.
And seems it did proceed further after that.

Error while burning bootloader.`

It throws an error about burning bootloader.
Is there a quick way to validate whether it went through or not ?

MCUdude · 2017-02-11T12:53:58Z

Woah, thats great! the last error (avrdude: verification error; content mismatch) is a USBtinyISP related, and is nothing to worry about. The USBtinyISP doesn't actually support devices with more than 64kB, but works fine on the ATmega128 despite the error.

Your ATmega128 should now have a boatloader, and the LED connected to PB5 should flash twice every second or so.

shaktidhar · 2017-02-11T14:30:01Z

One more success story here. The led is happy blinking... (It seems I did something early which led to the led getting burnt out.)
I noticed there is an instruction for adding 1K resistor.
Happy day and happy end to the week.

More power to you Hans.

yo8tww · 2017-02-11T15:47:11Z

I can confirm the bootloader on 128A is ok, and it can be programmed succesfully via an FTDI ( in my case, an FTDI 232RL onboard mounted).Have a nice weekend, mates..

hi MCUdude
I have problems uploading the bootloader for atmega128A.
