Afternoon,
I'm having a bit of trouble compiling a custom firmware for a new 7i92TF. What I'm after is a config for a G540 on P1 and a Mesa 7i76U on P2 (or vice versa really, not fussed). I have been attempting to build a custom firmware that fits this config, but cannot get the Field I/O via SmartSerial to resolve correctly.
Where I'm at:
- Have the latest source+fimware from Mesa (www.mesanet.com/software/parallel/7i92t.zip)
- 7i92T connected to a machine w/ new install of LinuxCNC (2.9.4 + all apt updates),
- 7i76U on P2, +5v from the parent card and 12v applied to the field power.
- mesaflash connects to 7i92T, write the supplied 7i92t_7i76x2d.bin firmware and reload
- get the SmartSerial info w/ mesaflash ... --sserial, finds the 7i76: ...7I76 GPIO+SPINDLE (unit 0x1000E070)..
- check w/ hal: can load the hostmot2 driver, connect to the 7i92T, ss finds 7i76, test I/O, can detect inputs high/low
- hardware thus seems to be ok, and behaving as expected using the prebuilt firmware.
- Running Efinity v2021.2.323.4.6 on WSL Ubuntu 24.04 (this appears to be the version the seveni92t project was last compiled in, have also tried the latest Efinity version w/ same outcome)
- Using the source from 7i92t-hm2/seveni92t.xml
- uncomment line 114 of TopEthernet16HostMot2_efx.vhd (appears to be the top file for the project?)
114: use work.PIN_7I76X2D_34.all; -- seed 5
- comment line 110
110: --use work.PIN_MX3660X2D_34.all; --seed 4
- clean build, creates a valid binary file
- this is the minimum reproducible, tried much fiddling with the source working back to here.
- Flash new bin to the 7i92T and run same tests, no SS/Field IO

Dumping the hmid, the outputs (for factory firmware and the freshly compiled) are identical with the exception of line 11:
Clock High frequency: 175.0000 MHz on the new firmware and
Clock High frequency: 180.0000 MHz on the supplied.
I also note that comparing a hex dump of the two bin files shows significant differences, but I'm not familiar enough with the toolchains involved to know if building on different environments should lead to variance in output.
Any suggestions appreciated. Cheers.
