how to install mesaflash

Hi, this should be simple but not, I have in my sources.list ... deb buildbot.linuxcnc.org/ buster buster master-rtpreempt, and then invoked sudo apt install mesaflash, but it is not found, can someone tell me where to get it?
Also I need to install the hostmot2 stuff, but not sure about that either.
I lost all my stuff when my hdd failed and am now trying to rebuild everything
thanks is advance
Eric

The instructions are at the bottom...

thanks, that's got me going., probably more questions and confusion yet to come

I spent the last week knee deep in this topic, and could only provide this pointer due to the excellent support of Tommylight, Rod and PCW

I'm not really sure I helped you here. Everything I know about Mesaflash I was taught by PCW!

I unzipped the 5i25.zip folder after installing mesaflash and ran sudo mesaflash --device 5i25 --verify 5i25_g540x2.bit but it responded with Can't find file 5i25_g540x2.bit,
Mesaflash and 5i25 bit files are in my Downloads folder at the moment, is there a particular file structure I should use.
I originally flashed the board a couple of years ago, my hdd failed and I'm trying to rebuild it all but I must be getting old as I cannot remember how to set this up
Any help appreciated

Thanks tommylight, where does mesaflash look for the .bit file? I created a new folder under /lib/firmware so the bit files are now under /lib/firmware/hm2/5i25 and in the configs subfolder, but mesaflash still cannot find the board. I am completely lost with all of this.

Mesaflash has no idea where the firmware is located.
You can either put a full path to the firmware in the command line
or run mesaflash in the directory that contains the firmware files.

sudo mesaflash --device 5i25 --verify /lib/firmware/hm2/5i25/somefilename.bit
if somefilename.bit is in /lib/firmware/hm2/5i25/
or
sudo mesaflash --device 5i25 --verify somefilename.bit
if somefilename.bit is in the current working directory


Note that verify is not useful for determining what type of firmware is loaded
as even a recompile of a bitfile from the same source will not match
even though it will be functionally identical

A better way to check loaded firmware is to use the --readhmid command

yes, I tried that running mesaflash in the hosmot2 directory but is still says board not found, (I assume it means the physical board) so I have missed something in setting it up, BTW I run Pncconf wizard and can control the steppers Ok through that, but when I try to run it I get loads of command not found errors, I have not set something up correctly.
Thanks
