Cant flash card for pi 4

Reformat card? Sounds like an incorrect file format. It should be formatted as FAT file format.

Can you navigate on it through your file browser?

Yes I did reformat image is on card but it won't boot but boots with pre flashed card is Eprom corrupted?

@duce-robot

Did you use SD Card Formatter to reformat the card and then try belenaEtcher to write the image to the card?

The suggestion above that mentions it should be formatted as FAT suggests to me using Windows formatter, which is not the correct methodology.

Using windows built-in tool for formatting was not suggested or mentioned.

But that being said, using windows to format an SD card will not make a difference except that it will not format a card over 32GB. You might as well use a third party formatter since it doesn't have a limitation if you are using larger SD cards. But since most installs require 8GB minimum, if you are just installing and you are not using a 64GB or larger card it will be fine.

Here is the official Raspberry Pi article on the subject.

I stand somewhat corrected!  Thanks for that link, it helped a lot to understand it from the Raspberry Pi perspective.  Now if I could just understand why a Windows 10 machine can't read a SD Card after the card has been booted at least once in a Jetson Nano!

Jetson Nano uses an ext4 file format. Thankfully Linux is free and easy to setup a dual boot system. But this did make me think about ways to access my Linux drive from windows. A quick google search came up with this.

Appearently there is also Ext2Read.

I will have to try these out. I've had to transfer files on the Linux side. I hope this helps.

Thanks again for the link!

@robo-pi take a look at the link in madmisha's post above.

@codecage

Looks interesting.  I saved the link.  I'll  look into it someday if I can ever find the time. 😊 

I haven't fired up a Jetson Nano in quite some time.   I've been working with my Raspberry Pies lately along with my FPGA boards.   In fact, I have so much to report along those lines that I'm hoping to make some videos on what I've been doing with the FPGA and CPLD boards.

I've also learned how to copy an SD system card to a smaller SD card.  This, of course, will only work as long as the system itself will fit on the smaller SD card.  It would take a long time to explain, but the crux of it is this:

I had installed Systems on my Jetson Nanos using 64GB SD cards.   However, the systems themselves take up less than 16GB of space.  In fact, they take up quite a bit less, more like 8GB of space.

So what I wanted to do was make back up copies of just the system on 16GB SD cards.  The problem is that you can't clone from a larger card to a smaller card.   However there is a way to reduce the system to fit on the smaller card using a utility called Gparted.   It's a fairly involved process but it does work.  This allowed me to reduce my systems to 16GB SD cards without having to reinstall and reconfigure everything from scratch.

In any case, for now I'm still working on the frame of my Caravan and trying to squeeze in other work on the side like painting my entire house. 🤣 

So yeah, I'm keeping pretty busy lately.  I do the FPGA work at night.  But I haven't fired up a Jetson Nano in over a month.  I"ve been working on Raspberry Pies and also using Quartus II on Windows.  Lots to report on FPGAs, VHDL, Verilog, and also using schematic CAD to design FPGA and CPLD.   I'm hoping to have some videos out on that topic eventually.   Probably in the late fall or winter.

@robo-pi

Good to hear from you Robo-Pi!  And I think Bill will be getting back into the swing of things shortly.  It has sure been slow here on the forum with him running under the radar.

Can't wait to see a few more of your video.  By the Way, Paul McWhorter gave a Shout-Out to the DroneBot Workshop yesterday on his live YouTube video.  He mentioned the DroneBot Workshop first when asked about what other YouTube channels he would recommend to his viewers.  He was very complimentary of Bill's style, content, expertise, and the professional quality of his videos.

I can hardly wait to start making them.   In fact, I would love to be making them right now but that's just not possible.  It's only July and I already feel like I'm in a race with ol' man winter to get as much stuff done as I can.  In fact, I already know that I won't be able to complete everything I'd like to do.  But I'd like to get as much done as possible.  I need to flush out my entire heating system before winter.  Right now would be the perfect time to do that, but I can't even get to that project.  Hopefully I'll get that done before I need the heating system again.

@robo-pi I would really like to eventually move into FPGAs. If you have a channel I would love a link.

Allso, Gparted has saved me a few times when I made errors on my installs/hard drive migration. It's very handy.

I had the same issue about 6 months ago and I've been trying to remember what I did. I have not had much luck with remembering. I had successfully installed Raspian on my Pi 3 about 5 months earlier with no problem using the same method. I want to say that I downloaded a new formatter and imager. The first time I used Win32DiskImager. The second time I used balenaEtcher. If I remember any more details I will drop it here. I recommend trying both of those first.

As for SPI EEPROM issues, they recommend this procedure to check:

"If your Raspberry Pi 4 will not boot, it is possible that the SPI EEPROM has become corrupted. To check, remove the SD card, disconnect the device from power, then reconnect it. If the green LED does not flash, this indicates that the EEPROM has become corrupted."

There are ways to use the RaspberryPiImager to fix this but I would save that for last unless you confirm the issue above.

Also, more info might help. What are you installing and what size SD card?What OS are you running? We kinda assumed it was Windows but I realize that might not be the case. Here is the page for SD Card requirements from Raspberry Pi:

@codecage yes I did I used the pi imager also it goes to the card but says not support 

@madmisha yes I am using or trying all sizes  from 32 gig to 128 trying to flash ubuntu 18.04 bionic for raspberry pi 3 4 I'm using windows.
