TCB Q&A Forum / Re: Read .sys boot file

« Last post by antunes879 on Today at 12:17:34 PM »

Then this was also one of the purposes in trying to read the code, to see if anyone who wrote left a signature inside it, because the program itself has neither the company name nor the name of the program, to know who did.

Thank you anyway, any more questions I'm going to look at the forum.
And if there is a miraculous idea I'm open,  ....

The best path is to consult the people who built your USB tool.
You should read the book and wiki to understand what you are dealing with.

Hi antunes879

If you can help me with any kind of idea, so I can visualize the content, it would be great.

You could take a copy of  tinycore.gz  off of the pendrive and unpack it to see what's inside. You'll want to do that in a Linux
environment. This Wiki page has information on how to unpack the file:
http://wiki.tinycorelinux.net/wiki:remastering
The basic instructions are where it says:

Then, extract core.gz for adding/removing something:

I understand what program I should use to open the extlinux.conf file,
By the tinycore terminal itself? Do you have any specific commands for this?

I have read a bit about boot files, and they use a type of encoding where you use a file called "symbols", where you can use it to find out which drivers are being "called" at the time of startup. These files "symbols" and a compilation program, could show what is written in the file, experience on the windows platform with virtual studio code.

I do not know if it's true.

When I open in hexadecimal and binary programs, they can not translate the parts where the symbols are, because this file is missing.

I wonder if this is how it works with tinycore?

There is some command, so before uploading the system I can fall into the terminal, so I can navigate the pendrive?

I'm trying to do any line of thinking, otherwise it will have to be done manually to pass all content to a new system, I say typing, because either the program does not issue a report, it does not export any type of file, everything The contents, in the own machine.

If you can help me with any kind of idea, so I can visualize the content, it would be great.

Google says you can control it via /sys/class/leds/led0/trigger. What are the default contents (cat that file)?

I believe the green light indicates general activity and not only µSD read/writes.

Maybe this helps you find out:

Thanks. I took a look through the script and figured for my purposes just a simple command-line call

Code: [Select]

cat /proc/diskstats | grep mmcwold work well enough.

Definitely seeing the ACT light blinking without any changes to the numbers, and I can confirm that the numbers for mmcblk0 and mmcblk0p2 *do* change when I run filetool.sh... So I think this verifies that the ACT light must also show general activity, at least on the Pi 3.

Hi aug
Try placing  eth0  on  192.168.2.99

did it ... problem still exists .... not sure if it's really a network problem ... change the wlan stick tomorrow and add an usb hub with additional power

Raspberry Pi / [Pi 3] SD activity with no partitions mounted?

« Last post by jefferee on Today at 07:43:24 AM »

Pi 3, running piCore 8.1.5.

I'm using copy mode, with copy2fs.flg in /mnt/mmcblk0p2/tce.


Furthermore, in /opt/bootlocal.sh, I have the line
umount /mnt/mmcblk0p2
so that the SD card is unmounted after bootup.


But I am still seeing the green "ACT" light flash when I start up some software on the Pi... does this mean I still have I/O accessing the SD card, or is the ACT light indicating something else?


The software is for industrial control, using TCP sockets and tty ports (tty through a USB/RS-232 dongle) to communicate with external devices.
We really want to ensure that we aren't accessing the SD card at all following boot, to reduce the probability of the SD card being corrupted.


Any ideas? Can I see what processes might be accessing the SD card?
Thanks for your wisdom.
