Welcome to LinuxCNC.org

I went to use the CNC today and LinuxCNC would not load. I am not sure what could have changed. I tried to run pncconf to let it 'refresh' the configuration and found that I could not test the axis, HAL would not function.

I have been allowing Update Manager to do it's thing. The last time I ran LinuxCNC was June 2. I have changed monitors (not graphics card) so I did the installing software based Open-GL drivers with sudo apt-get install libgl1-mesa-swx11. I tried reseating the Mesa card.

I don't know how to proceed.

Here is the error when I start LinuxCNC.

It could be a hardware failure of some kind though those are pretty strange symptoms. That is, its pretty hard to find the card (which requires correctly reading two 32 bit numbers from the card), and then fail at reading another 32 bit number. And its unlikely a corrupted bitfille on board since the bitfile in the EEPROM will not load if the CRC is wrong.

I dont think LinuxCNC would be updated but if it was, others have reported that builds from July have a bug in the Hostmot2 driver

Can you try running the mesaflash utility which would verify if an independent (of LinuxCNC) program can access the card?

Mesaflash is in the 5I25 zipfile. You need to be root to run it.
running it without any command line options will print usage information
probably the easiest test is to run a verify with the correct bitfile (also in the zipfile)

No Joy. I do not know how to run Mesaflash. I changed the properties of the file to allow execution. Here is what I saw:

root@PowerEdge:~/Downloads/5i25/utils/linux# mesaflash
mesaflash: command not found
root@PowerEdge:~/Downloads/5i25/utils/linux# ls
7i76x2.bit 7i76x2.pin mesaflash source
root@PowerEdge:~/Downloads/5i25/utils/linux# mesaflash 7i76x2.bit v
mesaflash: command not found
root@PowerEdge:~/Downloads/5i25/utils/linux#

Stan

since mesaflash is not in the execute path you need to prepend
a ./ to its name

./mesaflash blah blah blah

forgot to say that since the utility needs to be run as root, you will need to type:

sudo ./mesaflash blah blah blah

Joy! Terminal log below:

After this, LinuxCNC ran properly.

Thanks for the help.
