[Amforth] Flashing AmForth to Arduino Leonardo

[Jan K. <kro...@ho...>]

Hi,

Flashing the Arduino Uno is giving no problems.

Try to flash the Leonardo.
I’m using the Pololu AVR programmer v2.1
This is my command.

MacBook-Pro-van-Jan-10:avrdude jankromhout$ avrdude -p m32u4 -c avrispv2 -P /dev/tty.usbmodem00230362 -U efuse:w:0xFF:m -U hfuse:w:0xD9:m -U lfuse:w:0xFF:m -U flash:w:leonardo.hex:i -U eeprom:w:leonardo.eep.hex:i

It isn’t working
Can someone help me with this problem.


Cheers,

Jan

Jan,

What error is avrdude reporting?

Kind regards,

Tristan,


This is what I get
Perhaps the fuse values are incorrect!

Jan,

Have a look at this:  

https://github.com/arduino/Arduino/pull/5182 <https://github.com/arduino/Arduino/pull/5182>

At some stage AVRDude changed the way it reads back the unused fuse bits and thus the e-fuse parameter in the command line had to be adjusted.  I had this problem with the Arduino Uno.  While I am not familiar with the Leonardo, your problem might be the same.

It appears to me that you are probably using the new settings with an old version of AVRDude…

Implying that you should probably change efuse:w:0xFF:m to efuse:w:0xCF:m or update AVRDude.

Peter

looking into old files of mine ... 2013-05-01

I have not succeeded with a leonardo either. Attaching did create a
serial interface (/dev/ttyACM0), however, after erasing leonardo's
flash, this disappeared. So maybe usb connection is not through a FTDI
chip? THIS is a highly questionable idea, be warned. But might be worth
to check the schematics.

https://www.arduino.cc/en/Main/Arduino_BoardLeonardo
https://www.arduino.cc/en/uploads/Main/arduino-leonardo-schematic_3b.pdf

There is no FTDI, as far as I can see, however, how erasing the
atmega32u4 flash results in not responding to the ISP programmer, is not
obvious to me. I succeeded in erasing once. Nothing after that.


Please note that the _atmega_32_u4_ is a quite different beast from the
atmega_328p. So fuse settings would be another candidate to check.

I didn't find my leonardo just now ... so I can't play with it.


Cheers,
Erich

Connect the Arduino Leoardo via a USB Hub to your Macbook. Most of the times that solves the USART logic voltage level problem.
This way I solved a problem I had with a Chinese Arduino clone. (Used a USB 2.0 Hub then).

Re: [Amforth] Flashing AmForth to Arduino Leonardo

[Tristan W. <ho...@tj...>]

Hello Jan, Erich,

I came across my Leonardo and remembered this thread.  I think Eric
is correct. There is no FTDI USB to serial chip. The USB connection is
provided by the ATmega32U4 itself.  The Leonardo bootloader enumerates
to the host as a CDC Class device (virtual serial port). However, once
the Leonardo has been flashed with the amforth hex files there is no
bootloader, and so no serial port via the USB connection. 

If you have access to a USB to TTL serial adaptor (5V) it is still
possible to use the RX1 and TX1 connection to the hardware USART to
host the AmForth interpreter. The file /appl/arduino/leonardo.asm
seems already setup to do this.

2266  ok

The fuses on my Leonardo were

Fuses OK (E:C7, H:99, L:CF)

Best wishes,
Tristan
