traumflug / simulavr Goto Github PK

When I'm trying use of simulavr in Eclipse it does not work. Below debug information from simulavr:

What's wrong?

Folks, Github is about to enforce 2FA (Two Factor Authentification). That's IMHO a pretty pointless burden. Quality control in Open Source isn't established by some door lock, but by eyeballs looking at the code. Git commit IDs are enough of a verification, same ID gives always the exactly same code (and even the very same commit message). And yes, Git has also a mechanism to sign tags and commits with a GPG signature. That's as safe as public code can be.

I'm not going to mess with my phone (only way to give a second factor) when doing development, so I'll lose control over this repository in a couple of days. For this reason, this repository will be archived in a minute. All my Github activities requiring 2FA will chease for the same reason.

Should I happen to pick up development on this project again, it'll appear on GitLab, or some other appropriate public Git server. Archived repositories stay readable, and I also have my local copy.

simulavr terminates prematurely on linux/amd64 with message: "FATAL: file traceval.cpp: line 212: add TraceValue denied: wrong name: 'PC', scope is 'CORE.'".
This behavior is caused by if(n.find('.') != (unsigned int)-1) check, in traceval.cpp:210 because string::find() returns size_t which is unsigned long, which happens to be of different (8) size than int (4). I'v created patch miso-@7141f50 that makes simulavr work on linux/amd64. Please review.

With this upstream patch applied I experience lots of interrupt losses (time 1A going full round instead of interrupting in time) with code which is known to work fine on a real controller. Code is Teacup, a 3D printer controller firmware, and pretty complex. More precisely the code in timer-avr.c, but there are other interrupts running continuously.

Now I'm wondering how I can simplify this complex firmware into a demonstration case which can be measured on the scope. I have no logic analyser, so "long time" measurements are limited to some 20'000 samples.

If I use the original simulavr git from clone git://git.savannah.nongnu.org/simulavr.git
the tcl example work as expected.

this is my configure:
./configure --enable-python --enable-tcl --enable-verilog --enable-dependency-tracking --with-bfd=/home/pat1/compilazioni/binutils-2.24/bfd/ --with-libiberty=/home/pat1/compilazioni/binutils-2.24/libiberty CXXFLAGS=-g CFLAGS=-g --no-create --no-recursion

and this the configuration for binutils 2.24:
./configure --prefix=/usr --libdir=/usr/lib64 --mandir=/usr/share/man --infodir=/usr/share/info --target=avr --disable-werror --disable-nls CFLAGS=-fpic CXXFLAGS=-fpic

in example/simple_serial rename .c in .c++
modify Maefile.am to compile with avr-g++

with avr-g++ I have to add -fpermissive options

Make do

The support for ATmega1284p does not work with Timer/Counter3. I tested in CTC mode but the interrupt routine for vector "TIMER3_COMPA_vect" (No.33) is never entered. The vector "TIMER1_COMPA_vect" (No.14) works just perfect. I verified the code on physical HW using an external logic analyzer. The code is correct and both vectors (14,33) are entered as expected.

See http://git.savannah.gnu.org/cgit/simulavr.git for recent history of git://git.savannah.nongnu.org/simulavr.git

One of the features I like is that it compiles on my Mac, but then I'm not sure how to invoke the standard dist and get the serial-in/serial-out like your fork provides with SIMINFO_* mechanism.

Will add here more:

using this patch:
pat1@1a918c7

and a standardard build for arduino uno
defining a serial device working at 9600 baudrate I have to use this command to get the serial stdin/stout to work well:

simulavr -d atmega328 -z -b 9600 -F 32000000 --file mqtt_ethernet.cpp.elf

but the arduino uno board is a board with 16Mhz clock

using:
simulavr -d atmega328 -z -b 9600 -F 16000000 --file mqtt_ethernet.cpp.elf
puts wrong character in the stdout serial monitor

Any suggestions ?
