Error in prebuilt serialgateway?

[bvlet]

After not being able to connect to port 8888 after a reboot, I tried to start serialgateway manually:

# /bin/sh /tuya/serialgateway
/tuya/serialgateway: line 1: syntax error: "(" unexpected

Could it be that there's an error in the provided prebuilt serialgateway.bin?

It's not a shellscript! Run without /bin/sh :)

Also, what's in the ps list after you reboot?

Did the serial gateway make it across ok? Check file size matches. What happens when you run just /tuya/serialgateway?

[bvlet]

Looks like it....

In my explorer it's 47,6 kB.

I also tried the commands over Serial connection, logged in as root, but that makes no difference...

Running just /tuya/serialgateway gives an error:

# /tuya/serialgateway
Illegal instruction
#

[banksy-git]

Can you run this on your device. Assuming you got serialgateway.bin from here It should be the same as this:

# md5sum /tuya/serialgateway 
9f783720da1392f2f6589c2debb91bf0  /tuya/serialgateway

If it matches, can you post output of:

cat /proc/cpuinfo

[bvlet]

Nope, doesn't match.... I re-downloaded with your link and replaced the file. No change. output is this:

sh: /usr/bin/xauth: not found
# md5sum /tuya/serialgateway
e1602a45d7033fed5372ee93a9a2599d  /tuya/serialgateway
#

CPUinfo is like this:

# cat /proc/cpuinfo
system type             : RTL8196E
machine                 : Unknown
processor               : 0
cpu model               : 52481

tlb_entries             : 32

WHen I check your file in powershell, I see that I do get the correct MD5hash.....

PS C:\> Get-FileHash -Algorithm MD5 serialgateway.bin

Algorithm       Hash                                                                   Path
---------       ----                                                                   ----
MD5             9F783720DA1392F2F6589C2DEBB91BF0                                       C:\serialgateway.bin

PS C:\>

So somewhere the file is changing?

[bvlet]

YAY! I found it! At 3:19 AM.... I'm doing this from my work laptop which is Windows 10. So I used powershell to issue the cat command to transfer the serialgateway.bin. For some reason this "corrupts" the file. I just installed WSL(Ubuntu) and issued the command from there. After checking the MD5 tag on the hub and finding that it is identical to the one you sent me, I rebooted and voila! HA immediately connects through port 8888!

Thank you for your support. As always it was a Windows problem at last..... :) Maybe you should put that in your instructions ;)
