Remora - ethernet NVEM / EC300 / EC500 cnc board

Category: Computers and Hardware

Hi Guys, I'm pretty new here and just getting started with LinuxCNC, I've been retro fitting a rf31 mill and have a NVEM V2 I was using with Mach3 on an old laptop. the laptop started to play up and lost all my motor settings so i decided to ditch it all and buy a Raspberry Pi 5, load it with LinuxCNC and set it up solely for this machine.
I recently got my STlink all setup and now I need to confirm which bin file I need to download from GitHub? is it the Remora-NVEM-STM32-1.0.0.bin file in the Remora-NVEM/firmware directory or the Remora-NVEM.bin file in the Remora-NVEM/Remora-NVEM-STM32/Firmware directory? 
I'm going off the Scott 3D Youtube videos, but the GitHub info seems to be a bit out of date. Is any of the info in those videos still up to date or should I be looking elsewhere?
Thanks

7i95t firmware brick because i flashed a 7i95 bitfile in the fallback

Category: Driver Boards

hello LinuxCnc Community,

i recently bought a 7i95t with a trion fpga from the company efinix on it, luckily i flashed a 7i95 bitfile to the fallback and now i bricked the firmware so im not able to get a connection to the mesa card over ethernet(CR16 is steady on after powering up the mesa card, which indicates there is something wrong with the fpga config), what makes sense...

After reading the 7i95t datsheet, chapter"Host Interfaces" it says "DO NOT write 7I95 bitfiles to the 7I95T", yeah shit happens...
now i have some questions how to get the 7i95t working again?!

So theres a connector "P2 JTAG" on the 7i95t where you can flash the correct bitfile to the fpga using a hardware interface and the efinity software (there is a free license aviable on their website)
 what kind of interface do i need? do i need a development kit from efinty or can i use other brands jtag interfaces like  410-299 | Digilent JTAG-HS3, Xilinx-Werkzeug | RS

what bitfile i have to flash? 7i95td.bin?
how to flash the bitfile to the fpga with the jtag interface adapter using the efinity software?

i hope theres someone out there, whos so deep into this topic, who can help me :D
thanks in advance!

best regards Marco

I think a pop up window with a warning message on startup in gmoccapy 2.10 might be more helpful as there are going to be a number of users updating from previous versions to 2.10.
 

I adsolutely agree, but I dont know how make it.
