Running released binary on a Raspberry Pi 3B (Raspbian 11 = "bullseye")

[lure23]

I'm mostly using probe-rs but would now need to set up espflash as well, on a Raspberry Pi.

I noticed there's a prebuilt release of 3.3.0 for armv7-unknown-linux-gnueabihf - GREAT!

Downloaded, scp:ed over to the Pi, launching gives:

$ ./espflash 
./espflash: /lib/arm-linux-gnueabihf/libc.so.6: version `GLIBC_2.33' not found (required by ./espflash)
./espflash: /lib/arm-linux-gnueabihf/libc.so.6: version `GLIBC_2.32' not found (required by ./espflash)
./espflash: /lib/arm-linux-gnueabihf/libc.so.6: version `GLIBC_2.34' not found (required by ./espflash)

This looks similar to #454 - which was resolved.

My options are:

a) upgrading to Bookworm - would like to avoid that, since it seems like a full reinstall. My Pi is stable as it is, and I have no other urgent need to upgrade.
b) cross-compile; what I do for probe-rs

Perhaps my question is: is the 3.3.0 binary release expected to work on Raspbian OS 11 ("bullseye")?

As a side-note, I was able to get espflash running, via cross-compile, with the libudev feature disabled:

$ git clone https://github.com/esp-rs/espflash.git
$ cd espflash
$ git checkout v3.3.0
$ cross build -p espflash --release --target=armv7-unknown-linux-gnueabihf --no-default-features --features=cli
   Compiling espflash v3.3.0 (/project/espflash)
    Finished `release` profile [optimized] target(s) in 1m 11s

On sudo-capable RPi account:

$ sudo usermod -a -G dialout probe-rs    # yes, the user-id for this is `probe-rs` ;)

However, launching such a result causes:

$ espflash board-info
[2025-02-02T20:32:28Z INFO ] Serial port: '/dev/ttyUSB0'

If there's a way to cross-compile with the libudev feature, I'd be interested to know. I have pkg-config and libudev-dev, but likely only for x86, not ARM target. But this will do.

You don't need a full reinstall to updated a debian installation ;D I have a server running that started as debian8 and is running 12 now only updating via apt :p

But problem aside in the past i cross compiled probe-rs for raspberry pi3b+ via cross. Building espflash should be even simpler. It just was something like cross build --target armv7-unknown-linux-gnueabihf --release but you need to obvious make sure that the container build is using a older glibc that you are running on your pi with debian11.

Thanks @Vollbrecht

I got the remote espflash working last night, as explained in my comment.

What remains is:

•  would the released armv7-unknown-linux-gnueabihf binary be expected to work on "bullseye" (11) or does it require a later OS. If someone answers here, this Issue might work as documentation, even when closed.
•  cross-compiling espflash with the default features (libudev)

None of this is a personal itch for me, any more. I got the cross-compiled version up and running, and will document the steps in a repo I own. Eventually..

It requires a later OS, as it was built with gh-hosted-runners that don't support that GLIBC version anymore.
