Error in 7i96s firmware update file to connect with 7i77 result Checking file...

Hello everyone, please, I need help updating the firmware of the 7i96s board to recognize the P1 host connection with 7i77. I'm a beginner and I may be making some basic mistake. Please any tips help.
Below is the update command:

cnc@cnc:~/Documentos/7i96s/configs/hostmot2$ sudo mesaflash --device 7i96s --addr 10.10.10.10 --write 7i96s_7i77d.bin --reload
result:
Checking file... Invalid bitfile header!

The directory is www.mesanet.com/software/parallel/7i96s.zip

Below is the type of board version I'm using:


cnc@cnc:~/Documentos/7i96s/configs/hostmot2$ sudo mesaflash --device 7i96s --addr 10.10.10.10 --readhmid
Configuration Name: HOSTMOT2

General configuration information:

 BoardName: MESA7I96

Yes, The electronic board says 7i96s. When purchasing, the 7i96s was chosen. The board layout is from 7i96s.
Is there any jumper or configuration to enable the card update, perhaps some necessary operating system permission procedure? I'm using LinuxCNC 2.8.4

You need an up-to-date version of mesaflash

github.com/LinuxCNC/mesaflash

(Build instructions at bottom of page)

Thank you very much. When upgrading the system from LinuxCNC 2.8.4 to LinuxCNC 2.9.2, I got the newest version of the MesaFlash software which was 3.4.0 and now it is 3.4.9 on this new system. With this I was able to update the firmware successfully. But unfortunately I have not yet been successful in recognizing the 7i77 board in the LinuxCNC system. I'm using the LinuxCNC Pncconf Wizard, and the ports on the 7i77 board don't appear in place of the P1 connector, they don't appear in the configuration settings, please, is there any other procedure for the board to be recognized?Pncconf does not appear 7i77

Halshow does not appear 7i77

below the update carried out successfully! but without recognition of the 7i77 board even after restarting the system and electricity

The 7I77 will not appear in halshow until you:

1. Have the 7I77 connected to the 7I96S P1 connector with the proper cable

2. Have 5V power applied properly to the 7I77 (and the 7I96S P1 power option matches the 7I77 5V option)

3. Have field power applied to the 7I77 (and 7I77 W1 Left)

I don't think pncconf knows how to make a 7I96S+7I77 configuration so you may need to merge
a plain 7I96S configuration with say a 7I92+7I77 configuration (for the analog/encoder/7I77 I/O setup)

Thank you very much, HALSHOW has now appeared in the window. The green LED on the 7i77 lit up with OK status
