I installed from Official LCNC ISO to N150 PC , and right after did this,

sudo apt update sudo apt upgrade　

I got error ,
dpkg  initramfs-tools error (--configure):
error exit status 1

My questions are
1) Is it OK to use LCNC in this situation ?
2) Are there any ways to solve this error ?


 

Do you get near 0V on the analog output
when the 7I97T is powered but LinuxCNC is not running?

Thanks tommylight but I'm trying to build from master branch. Probably should have mentioned that.

What program  printed the error message?

Are you using the latest mesaflash?

Could you JTAG program the FPGA chip and get Ethernet access?

If so what does

mesaflash --device Ethernet --addr [card_ip_addr] --verbose

print?



 

Yes it has been going on for a long time.
Very long latency, it is almost like it isn't using a RT kernel.

That seems to be ok.
The error message is in the output from the linuxcnc command
 

And if you look in the ethercat-conf.xml you find the word BLANK
 

In place of BLANK there should be one of the hal types u32, s32, float-ieee, bit.
Have a look at the ethercat-conf.xml in this example I often refer to
github.com/dbraun1981/hal-cia402/tree/main/example
Modify both the halType and the halPin .

This example also shows how you use the cia402 component to
connect the servo drives to the joints.


 

Perfect, thanks! I skimmed over that page too fast trying to find index only homing and overlooked that detail. I guess I was depending too much on searches which were not getting me anywhere.

Hi PCW,

I managed to brick the firmware as well while following your instructions above.

I downloaded the Efinity software, along with the flashing utility from the link you provided. When I attempted to compile the project, I received the error:

“Project contains some invalid configuration. Please see details in console.”

It appears that some files may be missing.

I then tried using files from Mesa and was able to compile successfully. However, when I attempted to flash the board, I encountered the following error:

“ERROR: The FPGA given in the bitstream file does not match the FPGA you are trying to program. Check that you are using the correct bitstream file.”

Thank you in advance for your help.

Best regards,

happy to help! glad you got it sorted out!!
