Writing fusebits to the MCU from a file does not working

[masya-chel]

I am trying to write fusebits to the MCU from a file, this function does not working - an error is displayed. See the screenshots below.

avrdude.exe: Device signature = 0x1e9307 (probably m8) avrdude.exe: reading input file "C:\CLI\AVRdude_CLI\fw_write\high.txt" avrdude.exe: fileio: invalid operation=0 avrdude.exe: read from file 'C:\CLI\AVRdude_CLI\fw_write\high.txt' failed

If I try to read fusebits from the MCU to a file, then all works correctly - files with the names "high" and "low" are created in the folder, and the value of fusebits is contained inside the files. See the screenshots below.

If I try to write fusebits to the MCU directly from the console, then fusebits are written correctly. See the screenshot below.

Tested on avrdude versions: 6.3; 6.4; 7.0. Tested on microcontrollers: ATtiny13, ATmega8. OS: Windows 7 x64.

If I try to write fusebits to the MCU directly from the console, then fusebits are written correctly.

That suggests that something in your other (GUI, whatever it might be) execution environment must be strange.

However, what really puzzles me:

avrdude.exe: fileio: invalid operation=0

FIO_READ is 0, but why does the switch/case instruction falls into the default clause?

I'm afraid noone outside your GUI environment might be able to reproduce that.

[dl8dtl]

My only other idea: is it really sure that both invocations (GUI and commandline) are calling the exact same binary?

FIO_READ and FIO_WRITEmight be a little too generic as names. So if anyone else in the toolchain defines FIO_READdifferently than 0, and that makes it into the switch/case instruction in fileio.c, then passing a 0 will trigger the default case in the switch.

[masya-chel]

is it really sure that both invocations (GUI and commandline) are calling the exact same binary?

I can re-test the fusebits writing with the enabled avrdude option "verbose output" (-vvv). This option displays the full paths to the avrdude executable file in the terminal.

In both cases, command line calling the exact same binary, located at: C:/CLI/AVRdude_CLI/avrdude/avrdude.exe

[dl8dtl]

Who produced the binary?

[stefanrueger]

This is correct behaviour. The file formats :d, :h, :o, :b are only implemented for output (ie, when reading the memory), not for input (ie, when writing to the memory). This is documented in

$ man avrdude

Look for d decimal; this and the following formats are only valid on output.

You should be able to use hex, octal, decimal or binary with the immediate :m format. Try -U memory:w:$(cat file.txt):m or similar in bash (have not tried).

[stefanrueger]

It's a reasonable extension for AVRDUDE to implement :x, :o, :d, :b for input, too, but unclear how much effort should go into and how to prioritise. In the short run the error message could be a bit clearer, so instead of invalid operation=0 would be better to say "formats :d, :x, :o and :b are not implemented for input"

[masya-chel]

This is correct behaviour. The file formats :d, :h, :o, :b are only implemented for output (ie, when reading the memory), not for input (ie, when writing to the memory). This is documented in $ man avrdude

In the avrdude documentation, I did not find any restrictions on the read-write formats used.

See the avrdude doc. Chapter 2: Command Line Options -U memtype:op:filename[:format]

[dl8dtl]

In the avrdude documentation, I did not find any restrictions on the read-write formats used.

From the man page:

" d decimal; this and the following formats are only valid on output."

[dl8dtl]

I agree that a better error message is due.

[masya-chel]

Look for d decimal; this and the following formats are only valid on output.

I don't use the decimal format! I use hexadecimal format to write fuses.

[masya-chel]

In this case, it is necessary to explicitly write restrictions for each format flag in the documentation. The current documentation implicitly hides important information of one flag about another flag.

[mcuee]

It's a reasonable extension for AVRDUDE to implement :x, :o, :d, :b for input, too, but unclear how much effort should go into and how to prioritise.

@stefanrueger With PR #1042 to address the documentation issue, I think this is probably not a priority and not that necessary either.

[dl8dtl]

I don't use the decimal format!

"this and the following formats"

[dl8dtl]

I extended avrdude.1 and avrdude.texi in the PR as well.

[masya-chel]

Ok, thank you
