Test program for AVR and simavr.

Both 'hellosimavr' and 'simavr' require a new version of the avr toolchain.
|
|
OpenSUSE is too old. So grab a pre-built one and install it (tarball). This
|
|
should be the first thing.

|
|
|
|
The 'hellosimavr' test program is taken from:
|
|
|
|
git clone https://github.com/larsks/pipower
|
|
|
|
Go to 'tests/hellosimavr/sim' and type: make
|
|
|
|
erniep@gracie:(sim)$ pwd
|
|
/nas/erniep/Development/seer/tests/hellosimavr/sim
|
|
|
|
erniep@gracie:(sim)$ make

Install simavr, the AVR emulator for AVR microchips. It interfaces with avr-gdb, which
|
|
Seer is happy with.
|
|
|
|
https://github.com/buserror/simavr
|
|
|
|
|
|
Now run the tests.
|
|
|
|
In one terminal:
|
|
|
|
$ simavr -m attiny85 -f 1000000 pipower.elf -g
|
|
|
|
In another:
|
|
|
|
$ seergdb --gdb-program /usr/bin/avr-gdb --connect :1234 --sym pipower.elf
|
|
|
|
You will need to set the initial breakpoint in main(), then "continue".
