After rebase, the firmware still doesn't work. It returned the statux 0xdead on the ALIVE packet. We don't know how to diagnose since we don't have the datasheet for the chi= p . I checked: 1. The current iwm's init code before waiting alive packet is similar to linux's iwl driver. I don't know if there is a necessary register we should set. 2. I see the version 34 of the loaded ucode from TLV field. That means the system doesn't load an empty file. But, I am not able to confirm if each byte is correct. The current work I have posted on github https://github.com/wjguo/freebsd/pull/1 It is welcome to give ideas of how to make the firmware running successfully. Thanks.
