The first thing I would do is "cat /etc/iptables.ipv4.nat".

Ernst

My /boot/cmdline.txt is dwc_otg.lpm_enable=0 console=serial0,115200 console=tty1 root=PARTUUID=a024b7d3-02 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait modules-load=dwc2,g_ether Have you tried to specify a "fake" mac address in cmdline.txt ? see this thread https://www.raspberrypi.org...

Sorry but I'm not playing 20 questions on this issue. If you can't tell from the subject line and body of my first post what's going on then please don't respond. The tactic of starting a game of 20 questions is usually begun by those who don't have a clue about what's going on. It's used merely to...

[ The following is based on the previous posts: Why do you want to format the memory card. Seriously?!?!?! Look at item #4 in STICKY: 27 Common Pitfalls for Beginners. Etcher automatically reformats the card before installing any OS. Other sets of instructions include formatting. Two things 1) I ha...

Ernst

Bump... I have to get this resolved. After reading your posts I have this strange thought that your problem could be related to a duplicate IP address. I've been encountering a strange, frustrating and relentless issue which is threatening my job because the web server is constantly and randomly go...

Ernst

https://www.sdcard.org/downloads/formatter/ I looked at that. I didn't find a Linux version of the tool. I think this is a good point in time to give you some very important advice: when you have problem with a motorized vehicle (such as motor bike, automobile, motorized push chair, electric scoote...

Ernst

Getting the message: unable to open /dev/sdb: No medium found What am I doing wrong? I do not have anything that I can use to confirm my thoughts, according to me the problem is that you can not "format" an SD card. You can format a partition with a file system by using the assigned device name, li...

Ernst

I havent wrecked the card, does resizing wreck the card? I dont think so. After all the files in the partitions are intact. In that case there should not be a problem booting the raspberry pi, or are there problems ? The proper procedure is backup, practice, restore, practice, and repeat until succ...

Ernst

If anybody knows the files to be saved, I will save them , make a fresh install and restore the files. note: epoch1970 replied in the meanwhile but I will still give you my reply. The only person who can help you is yourself because you are the only person who knows what was changed to your system....

Sorry I read the line and corrected it .I made the PARTUUID =ec420e6d-01 and also ec420e6d-02. But there is no joy yet. cat cmdline.txt dwc_otg.lpm_enable=0 console=serial0,115200 console=tty1 root=PARTUUID=ec420e6d-01 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait quiet splash plymouth...

Code: Select all

 cat cmdline.txt 
dwc_otg.lpm_enable=0 console=serial0,115200 console=tty1 root=PARTUUID=a0f4964d-02 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait quiet splash plymouth.ignore-serial-consoles

did you read that line in cmdline.txt ?

Ernst

I think you will find the answer you need by studying this blog post

Ernst

Code: Select all

cat /boot/cmdline.txt

which should be in your case on sdc1

Ernst

I suggest you format the card and that you start from scratch using the "official" instructions instead of something you found on the internet: https://www.raspberrypi.org/documentation/configuration/wireless/access-point.md Hint: "denyinsterfaces wlan0" and editing "/etc/network/interfaces" is not ...

Ernst

That cable WAS DESIGNED and INTENDED FOR USE with IDE drives and NOT FOR THE RPi GPIO. It was your fault for using it, that fried your RPi, not the fault of the designer of the cable. saw this in one article: "....somebody put raw eggs in a microwave oven and it exploded upon turning on....causing ...

Ernst

Would that be before bootcode.bin, or inside it ? I tried a hex editor to change something according to some post somewhere. Of course, didn't help. What would that be ? I gave you some information, if there is something that can be done it might be possible that jamesh reacts when he gets back fro...

Ernst

Sounds like a bunch of fake capacity cards. Have you checked that they are what they say they are? Hey jamesh is there any debug info that can be turned on, passed to the boot firmware any way , shape or for, ? lol What I suspect is that the problem could be a time out, meaning initializing and rea...

Ernst

WoW! That is the (almost) worst performance I have ever seen ! Unfortunately I can not read the markings on the card. I looked into my archive and I found that the only* card with a similar performance that I tested was an 2Gbyte Eye-Fi Wi-Fi card. only* means cards with a size > 1Gbyte, I did test ...

My problem is that I could show you my samba configuration but it may cause new difficulties because of what I have configured. For this reason I will not show all the entries, except what may apply to your smbv1 problem. [global] server string = Samba %v on %h workgroup = WORKGROUP server role = st...

Ernst

Ernst, Yes the post about reading the topic and it having a discrepancy, was to perform the usb gadget test. And that failed with the 4GB card but worked with the 8GB card. In this test the only variant is the micro SD card, that implies that there is something with the type of card causing the pro...

Ernst

after all these steps I connected raspberry pi with my laptop using ethernet cable but does not detect raspberry pi's ip address. A few questions: 1) Is the ethernet cable a proper cable, or ISDN cable, or a home made cable ? 2) How many wires are used in the ethernet cable ? 3) Do you know the mea...

Ernst

Open Windows command prompt and do

Code: Select all

for /L %a in (1,1,254) do @ping -n 1 -w 30 192.168.1.%a|find "TTL"

Ernst

I have to be a bit difficult now, please read your post and confirm the following Ok So I read that topic and noticed a discrepancy in the link to the image, and the actual image name that it downloads, and specifically its the date at the beginning of the file name. not even close on the date, but ...

-Raspberry Pi Zero W v1.1 -various raspbian images(that would work on a 4GB card), including a raspberrypi-us-netinst -I booted with the 8GB card that has PiX10Hub imaged onto it, and (use |susb) commands do not work Let's check a few things: Please do the following, remove the memory card from the...

Ernst

If its some internal thing, then i'll dif into, but I can't even figure out where the boot is failing. If I was a doctor I would tell you to take two aspirins and come back in a weeks time. Please do the following exercise: go back to your first post in this thread and read every post you made. Did...
