mesaflash halts writing firmware was created by fehertamas
Hello everyone,
I've encountered an interesting problem, and would like to ask how could I resolve it.
I'm trying to get started on a new 6I25 board (default configuration in 5I25 compatibility mode)
(installed using the LinuxCNC 2.8.2 Debian 10 Buster PREEPT-RT ISO)
After going through the pcnconfig and setting up some permissions, linuxcnc fails with the following output:
I thought I need to update the firmware on the board so i tried doing that with mesaflash:the output of that command is the following:Then tried the same with the fix-boot-block flag:And this command just halts and spins the cpu on 100%.(left it alone for an hour a couple times)
This is the output from it:Anyone has any idea what could cause getting stuck? Or am I going the wrong direction with mesaflash?
Any Ideas welcome!
Cheers,
Tamas

as well as in the output of the shell command 'dmesg' and in the terminalI thought I need to update the firmware on the board so i tried doing that with mesaflash:

File type: BIT file
Error: BootSector is invalidsudo mesaflash --device 5i25 --fix-boot-block --write 5i25_7i78x2.bitThis is the output from it:
Checking file... OK
File type: BIT file
Erasing sector 0 for boot blockAny Ideas welcome!

Did you move any jumpers on the card?
If yes, shut down, remove card, set jumpers to default, plug in the card, power on.
If not, try a different PCI-E slot.
PCI-E slots can be shared with NVME, other PCI-E slots, SATA, WiFi, so ..... complicated.
You can insert the Mesa 6i25 in any PCI-E slot, be it X1, X4, or X16, it does not matter works in all of them.

There seem to be multiple problems here:
"Note: Using POSIX non-realtime"
Likely indicates a permission issue of some kind (why did you change any permissions?)

Hi, thank you for the quick reply to my case!
I've tried both default (33MHz PCI clock) and 6I25 compatible (66MHz PCI clock) configuration in multiple PCIe slots, that didn't help.
Although now I managed to get past the halting!
I've cloned the mesaflash repository (github.com/LinuxCNC/mesaflash) and built it locally to have the latest version by following the steps in the readme.
with the built version the flashing works!doesn't halt, finishes OK with verification.
working version: 3.4.2
version shipped on the iso: 3.4.0~pre1
Now the issue I'm facing right now is that the init LED blinks, which means it's using the fallback firmware after flashing it with:

1. Note that you should never use anything but a 5I25 (33 MHz) setup with 5I25 bitfiles
2. Does "sudo ./mesaflash --device 5i25 --readhmid" report reasonable values?
2. Does "sudo ./mesaflash --device 5i25 --readhmid" report reasonable values?

Solved the blinking issue, the problem was that I didn't do proper power cycling of the card after flashing it. After disconnecting the power and putting it back it has loaded the right firmware and the "sudo ./mesaflash --device 5i25 --readhmid" has the right output now!1.

Looks like the rtapi_app didn't have good permissions out of the box.
It's been fixed withSo now it loads and uses the realtime POSIX
But I suspect that's not the right way of solving it.
Perhaps I miss a step after the os installation?

Wow, good catch! Yes, seems like I still had permission problems.There seem to be multiple problems here:
"Note: Using POSIX non-realtime"

Looks like the rtapi_app didn't have good permissions out of the box.
It's been fixed with
sudo chmod 4755 /usr/bin/rtapi_appBut I suspect that's not the right way of solving it.
