I managed to get the firmware to spi flash (spansion fl032pif), also I have been able to enter through the serial console, my question is, there any possibility to remove the firmware checksum? Because when I did some change in I get an error in the boot "MAC SPCB field has failed".
This is the PCB --->
Its a OPENTEL HCB2-IR60
This is the boot log --->

This is the flash info -->
