Tried the test and nothing happened

[liborw]

Hi, I have tried the test from the README:

$ ./simavr/run_avr tests/atmega88_example.axf
AVR_MMCU_TAG_VCD_TRACE 00c6:00 - UDR0
AVR_MMCU_TAG_VCD_TRACE 00c0:20 - UDRE0
Loaded 1722 .text at address 0x0
Loaded 114 .data
Loaded 4 .eeprom

the produced gtkwave_trace.vcd is empty.

the produced gtkwave_trace.vcd is empty.

Try adding signals to the timeline
I was also confused because it does not print further information eg

Starting atmega88 - flashend 1fff ramend 04ff e2end 01ff
atmega88 init
avr_eeprom_ioctl: AVR_IOCTL_EEPROM_SET Loaded 4 at offset 0
Creating VCD trace file 'gtkwave_trace.vcd'
Read from eeprom 0xdeadbeef -- should be 0xdeadbeef..
Read from eeprom 0xcafef00d -- should be 0xcafef00d..
simavr: sleeping with interrupts off, quitting gracefully

Is it a bug or..? I see in version 1.0 it was ok.

Me too. No output past "loaded 4 .eeprom":

$ simavr/run_avr tests/atmega88_example.axf 
AVR_MMCU_TAG_VCD_TRACE 00c6:00 - UDR0
AVR_MMCU_TAG_VCD_TRACE 00c0:20 - UDRE0
Loaded 1706 .text at address 0x0
Loaded 114 .data
Loaded 4 .eeprom

but the gtkwave_trace.vcd file seems whole. Adding a couple -v flags to the command gave additional output:

$ simavr/run_avr -v -v tests/atmega88_example.axf 
AVR_MMCU_TAG_VCD_TRACE 00c6:00 - UDR0
AVR_MMCU_TAG_VCD_TRACE 00c0:20 - UDRE0
Loaded 1706 .text at address 0x0
Loaded 114 .data
Loaded 4 .eeprom
_avr_vcd_notify trace buffer resized to 51
Read from eeprom 0xdeadbeef -- should be 0xdeadbeef..
Read from eeprom 0xcafef00d -- should be 0xcafef00d..
simavr: sleeping with interrupts off, quitting gracefully

...but still not really the same thing as what's depicted in the README.

I built on Linux (with plain make), and also do not get a match for what is in the output from the README. Instead I get:

$ ./simavr/run_avr tests/atmega88_example.axf 
Loaded 1760 .text at address 0x0
Loaded 114 .data
Loaded 4 .eeprom
Read from eeprom 0xdeadbeef -- should be 0xdeadbeef..
Read from eeprom 0xcafef00d -- should be 0xcafef00d..

This is in contrast to what the README says; which has additional lines:

$ ./simavr/run_avr tests/atmega88_example.axf
AVR_MMCU_TAG_VCD_TRACE 00c6:00 - UDR0
AVR_MMCU_TAG_VCD_TRACE 00c0:20 - UDRE0
Loaded 1780 .text
Loaded 114 .data
Loaded 4 .eeprom
Starting atmega88 - flashend 1fff ramend 04ff e2end 01ff
atmega88 init
avr_eeprom_ioctl: AVR_IOCTL_EEPROM_SET Loaded 4 at offset 0
Creating VCD trace file 'gtkwave_trace.vcd'
Read from eeprom 0xdeadbeef -- should be 0xdeadbeef..
Read from eeprom 0xcafef00d -- should be 0xcafef00d..
simavr: sleeping with interrupts off, quitting gracefully

The output I got nearly matches for the lines that are present (differs 1760 vs 1780 for .text), but is missing several lines. Adding -v doesn't change it to add more output.

It produces a gtkwave_trace.vcd. But viewing it with gtkwave gtkwave_trace.vcd does not look like the output in the sample. :-/

Was this issue closed in error, or was it believed that a problem was fixed?
