Unable to reproduce tests/atmega88_example.axf results #486

Open jimustafa opened 2 years ago

Running

./simavr/run_avr tests/atmega88_example.axf

yields

Loaded 1722 .text at address 0x0
Loaded 114 .data
Loaded 4 .eeprom
Read from eeprom 0xdeadbeef -- should be 0xdeadbeef..
Read from eeprom 0xcafef00d -- should be 0xcafef00d..

which is inconsistent with the expected output documented in the README.

All the tests are passing...

I am on CentOS 8 and using avr-gcc installed through arduino-cli.

The README does not say that the program you build will produce that output, just "A program running with these instructions ... will display". Evidently an older version of run_avr with a higher logging level was used. Indeed, you can get closer by adding several "-v" options to the command.

So there seems to be no real issue here.

It has been logged before: #168 and #445. The main part of #168 (empty VCD file) is fixed, probably by #440.

Thanks for the references; yes, this issue (if even an issue) seems to be a duplicate.

So, this is just a case of the output shown in the README being out of date with the state of the main branch.
