Stereo Tool

Hello, tried to install the latest release of the 32-bit micrompx decoder tonight (version for raspberry) and got a segmentation fault.

PRETTY_NAME="Raspbian GNU/Linux 10 (buster)"
NAME="Raspbian GNU/Linux"
VERSION_ID="10"
VERSION="10 (buster)"
VERSION_CODENAME=buster
ID=raspbian
ID_LIKE=debian

BUG_REPORT_URL="http://www.raspbian.org/RaspbianBugs"

sudo ./MicroMPX_Decoder_ARM32
Segmentation fault

Thanks for reporting this! I've tested it here on different Pi's (2, 3 and 4) without any issues. So, I need more info to figure out what's wrong.

Did you upgrade from an earlier MicroMPX version that worked? Or is this a fresh install?

If you upgraded from an earlier, version, *maybe* something in the settings is triggering this. Please try the following:
- Go to your home directory, and rename the file .MicroMPX_Decoder.rc to something else, for example

mv .MicroMPX_Decoder.rc .MicroMPX_Decoder.rc.20210317

Then try to start MicroMPX again. If this solves the issue, please send me the old settings file so we can try to reproduce it here.

If this doesn't help, please try the following:

gdb ./MicroMPX_Decoder_ARM32
run
bt
disassemble
quit

(So, you start 'gdb' with MicroMPX_Decoder_ARM32 as argument, this will give you a new prompt "(gdb)" after which you can type the other 4 commands)

And paste the error message (last line from run) and the output of bt and disassemble here.

Quit anyway? (y or n) y

Quick note, I'm using a raspberry pi 1B+. Oldie, but with the latest released Raspbian. I also downloaded an older version of the Decoder but it gives the same error.

I think its due to the hardware revision of the Pi. On my Pi 4 it runs like a charm!

You need at least a Pi 2, we're using instructions that the Pi 1 doesn't support. So it makes sense that it crashes.
