If i use 2.9.0 or recompile the hostmot2 driver, must i update firmware in 7i92 FPGA?

As PCW mentioned in previous message:
"There is new firmware and support in LinuxCNC 2.9
for homing to index on pure step/dir systems if you want to try
it."

If yes, where can i find this firmware?

What hardware do you have?

LinuxCNC standard homing to index with a stepgen requires
firmware that include these features as standard bitfiles do not
have these features.

7i92 + 7i76 (on DB25 connector) + 7i85 (on ribbon cable) + 7i84

Here is a 7I92+7I76+7I85 bitfile with stepgens that have index capability:

Encoders 0..3 are on the 7I85 and share encoder index's  with stepgen index's 0..3
encoder 4 is on the 7I76 and has no stepgen index (just encoder index)
