7i95T errors with Mesa Configuration Tool v2.0.1

Hi,

I tried to search this issue but couldn't find it from the board, so here is my issue.
I recently acquired 7i95T board to replace my parallel BoB.
7i95T is not supported by PNCConf, so I installed Mesa Configuration Tool v2.0.1.
It detect 7i95T correctly on "Machine" tab's Mesa Setup with IP 10.10.10.10.
----Check for Boardreturned: Success ETH device 7I95T at ip=10.10.10.10----
Problem starts on "Firmware" tab. With downloaded firmware, "7i95t_d.bin" which is default F/W checked with "Verify", it doesn't update "Options" group box for Step Generators or Encoders. They both set to n/a and I can't change. (no available options but N/A). Read HMID reports the board as "MESA7I95" (without T) and having 6 StepGen and 6 MuxedQCount. "Read PD" also reports all 57 pins correctly.
Problem is this N/A leads to main.hal without stepgen configuration as below.

loadrt [HM2](DRIVER) board_ip=[HM2](ADDRESS) config="sserial_port_0=00000000"

Another issue is that once I setup JOINT 0 with X axis stepper parameters, Build Config and run LinuxCNC, it crashes with following errors.
It says hm2_eth has found unrecognized board 7I95T and discovered it and port names will be wrong. Not sure this would be an issue.
Actual reason that LinuxCNC is crashing is HAL is written with (BOARD) = 7i95t, but hm2_eth detects it as hm2/hm2_7i95.
So the hal line that is written with hm2_7i95t.0.watchdog.timeout_ns is not found error.
I manually edited BOARD name to 7i95 in INI, crash issue is resolved but AXIS doesn't move the stepper, so I'm stuck here.
Any help would be appreciated.

The 7I95T requires using LinuxCNC master (2.10)

I compiled LinuxCNC 2.10 from Git.
Now LCNC recognize the board and port names are reported correctly.
But hm2 still creates hm2_7i95 instead of hm2_7i95t. So board name need to be manually edited to 7i95 when used with mesact.
Stepper is still not responding but this could be my config issue. I'll back on this if I get stuck.

Now LCNC recognize the board, I used PnCConf tool to setup 7i76e board with my joint parameters, then manually replaced all 7i76e with 7i95 in hal.
It works fine and stepper responds correctly.
With some tuning I guess basic motions will be restored.
Next goal is to control VFD using RS485.

Quick search told me it can't be done.
I may need to flash PWM firmware to 7i95T and use it to control VFD then.

There is experimental support for MODBUS using the serial PKTUART interface so that's a possibility

JT,

I think you get only partial of the problem.
I cloned github.com 2.0.2 and tried.
There are many problems but the first two things to make mesact work with 7i95 are
1. mesact creates "BOARD" in .ini as 7i95t while LinuxCNC detect it as 7i95. So main.hal line of below line will crash LinuxCNC upon start as it can't find hm2_7i95t.0 but there is hm2_7i95.0

setp hm2[MESA](BOARD).0.watchdog.timeout_ns 5000000

I'm not sure whether this is mesact's problem or LinuxCNC's problem that it detect the board as 7i95 instead of 7i95t. I think the latter but I know nothing about LinuxCNC's internal...

2. After selecting the firmware, mesact tool doesn't set Step Generators, Encoders number correctly. And simply disable to update. This leads .hal not that usable.
