About the installation of bcm4366c0

[maple-42]

I am now attempting to install bcm4366c0 though, 7.Enter the created subdirectory nexmon_csi and run make install-firmware REMOTEADDR=

to compile our firmware patch and install it on your RT-AC86U router.

I am having trouble with the error below when executing here. bash: syntax error near unexpected token `newline'

How would you install it on the RT-AC86U router, and if there is a connection method, etc., I would appreciate it if you could tell me.

Thank you in advance.

I was able to resolve the error I wrote about earlier, but now I get this error. I hope you can help me with this, as reading #263 did not solve the problem for me.

For others it might be beneficial if you document the solution to your previous problem here.

Regarding your current error, please post the output of nexmon_csi/log/ass.log.

[maple-42]

Thank you very much.

I ran nexmon_csi/log/ass.log and got the following output.

bash: nexmon_csi/log/ass.log: No such file or directory

[jlinktu]

Ok, we talked past each other here. ass.log is a log file that gets produced during the step that is failing for you. You can find it your nexmon_csi patch directory in the log sub-directory. You can get the file's content for example like this (assuming you have NEXMON_ROOT in your environment / have executed source setup_env.sh in the same environment):

cat "$NEXMON_ROOT/patches/bcm4366c0/10_10_122_20/nexmon_csi/log/ass.log"

[maple-42]

Sorry, I am a beginner and do not understand well.

When I opened the ass.log, this is what I found.

Parser ERROR (file "src/csi.ucode.bcm4366c0.10_10_122_20.asm", line 125, col 9): xje [SHM(0x1724)], 0, skipdeaf+ 　　^ syntax error

Thank you for your reply.

[jlinktu]

Please run make clean and try again.

[maple-42]

I will try again from the beginning. Thank you very much.

[maple-42]

I was retrying and another error occurred.

Install python2 and change this line to #!/usr/bin/env python2.

[maple-42]

Thank you, I installed python2 and tried again, but I got the following error.

I modified it in my own way and it changed to this error.

I also encountered this error.

hi，I also met this problem and did you have slove it？Thx

scp is no longer available on the Asus AC86U with recent firmware images. You can either use an older firmware image that comes with scp or you can exchange the following line: https://github.com/seemoo-lab/nexmon_csi/blob/fdb25ef0e4e1402e968bb644d4914ad1a3d0a84d/Makefile#L365 with an alternative to copy the file over to the device, e.g.:

$(Q)ssh admin@$$REMOTEADDR '/usr/sbin/socat -u TCP-LISTEN:65535,reuseaddr OPEN:/jffs/dhd.ko,creat'& sleep 1; socat -u FILE:dhd.ko TCP:$$REMOTEADDR:65535

Note that this requires you to have socat installed on your machine.

```in 

Note that this requires you to have `socat` installed on your machine.

Thank you very much and I have done the getting started succesfully but when I went to the run 'nexutil' in the terminal of AC86U got this: admin@RT-AC86U-5360:/jffs# nexutil /jffs/nexutil: line 1: ELF

: not found /jffs/nexutil: line 2: syntax error: unexpected word (expecting ")")

can you help me or give me some advice to solve this problem? thx!!

[jlinktu]

That indicates that you compiled nexutil for the wrong architecture. Make sure to build it by following steps 8, 9, and 10 of the README's section bcm4366c0: https://github.com/seemoo-lab/nexmon_csi?tab=readme-ov-file#bcm4366c0

[lionlanlan]

Thank you. I have solved it by your advice.

[maple-42]

I rewrote what was stated and ran it, but the error occurred again.

COPYING TO ROUTER dhd.ko => /jffs/dhd.ko (Q)ssh admin@$REMOTEADDR '/usr/sbin/socat -u TCP-LISTEN:65535,reuseaddr OPEN:/jffs/dhd.ko,creat'& sleep 1; socat -u FILE:dhd.ko TCP:$REMOTEADDR:65535 /bin/sh: 1: Syntax error: word unexpected make: *** [Makefile:365: install-firmware] エラー 2

[jlinktu]

There was a $ missing at the beginning of the command. Please don't blindly copy&paste, always recheck commands, this one could have been easily spotted.

[maple-42]

Sorry, thank you very much. I apologize for the trouble.

[maple-42]

Sorry, I have been trying to find out how to fix the code. I modified the code and got an error so I looked into it but couldn't figure it out.

I have tried both wired and wireless with the same result.

Hi, I have the same problem, have you solved that?
