question about eeprom.py and sfputil.py

[ForzaTian]

Description

Can't execute eeprom.py and sfputil.py

Steps to reproduce the issue:

1. ls eeprom.py and sfputil.py in sonic
2. execute sonic command

Describe the results you received:

admin@sonic:$ ls /usr/share/sonic/device/x86_64-delta_dsc100-r0/plugins/
eeprom.py sfputil.py
admin@sonic:$ sudo decode-syseeprom
/usr/bin/decode-syseeprom : ERROR : cannot load module: /usr/share/sonic/device/"x86_64-delta_dsc100-r0"/plugins/eeprom.py
admin@sonic:~$ sudo sfputil version
Failed to load platform module 'sfputil': [Errno 2] No such file or directory

In fact I see the closed issue #1433 ,
may be it's the same case with me in sfputil.py, and I pull the commit in sonic-utilities, but didn't solve my problem.
So I want to know whether I missed something, any advice?
Thanks for everyone.

@pollyhsu2git thanks for your timely reply.
But when I pull the latest commit in today (Mar 6) ,and compile again, the outputs of the two commands on my board have no change.
So may I ask you whether you do anything before you execute the commands on sonic shell?

Thanks again for your info.

@ForzaTian, NO~ We did not do any particular before the decode-syseeprom / sfputil commands. The attached ZIP is our test log for your reference.

@ForzaTian , you can also download the latest image from https://sonic-jenkins.westus2.cloudapp.azure.com/job/broadcom/job/buildimage-brcm-all/

Does that work?

[ForzaTian]

@lguohan Thanks for your reply.
But I am developing our project now, the code haven't pushed into github, so there is no debs for our project in jenkins and the image could not run on our board.

May I ask one more question?
I check the boot log on my board and find syncd segfault such as :
syncd[1752]: segfault at 15f6978 ip 00007f281b7ca04e sp 00007f281aea0c68 error 4 in libc-2.19.so[7f281b738000+1a1000]
syncd[1795]: segfault at 3f65458 ip 00007f569b0aa04e sp 00007f569a780c68 error 4 in libc-2.19.so[7f569b018000+1a1000]

I'm not sure whether it has influence on .py execution, so in your experience , what may lead to that error? Could you give me some advice?
If you have no experience for that , please ignore that question.
Thanks for your help.

Hi all:
Finally, I found the reason for my error.
It because the "onie_platform" value in machine.conf is not correct , which has been amended in onie project onie commit .
It has been a long time since my last update onie code, so I pull & compile it, and install sonic again, all the commands can work now.
Many thanks for all of your help.
