      Ok. I got the device and I loaded Debian image M5_CoreMP135_debian12_20240628 from

      https://docs.m5stack.com/en/guide/linux/coremp135/image

      It did boot.
      However, upon boot it didn't resize the root partition to occupy whole SD card.
      As a result I can't install anything because there is no space.

      I had to use fdisk to resize /root partition (#5 for me, making sure I use same starting block and preserve filesystem type, see https://askubuntu.com/questions/24027/how-can-i-resize-an-ext-root-partition-at-runtime) and then
      resisz2fs command (something like resize2fs /dev/mmcblk0p5).
      It would be too hard for an average user to repeat that.

      Also the kernel on it is very old. 5.15.118
      On Raspberry Bookworm it is much newer. (6.x)

      There are many errors related to USB reported by dmesg.
      I have powered USB HUB and keyboard is connected via it.
      Keyboard works though.

      Is it possible for next versions to have image which would resize to SD card size?
      Same way as Pi OS does?

      Is it possible to have have newer linux kernel? I think USB errors might be related to old version of it.

      Thanks

        USB errors were my fault. I plugged usb 3.0 hub into usb 2.0 port.

        One more question:

        What are the tty devices names of RS-485 and UART6 under /dev?

        Thanks

                From what I can find, the /dev/ttystm0 2 and 3 could be UART ports

                  The mDNS service aka Zeroconf aka Avahi aka Bonjour is already enabled on the device, so if you have the client tools installed on your PC you can connect in SSH using the .local address like this:

                  ssh root@M5Core135.local

                  M5Core135 is the default hostname.

                  I cant get a ssh login with the latest Debian release. the default password return access denied in SSH

                    Finally getting around to looking at the GPIO's on the CoreMP135.
                    not getting far at the moment as it took all weekend to work out how to expand the OS to use the whole card then get it to install GPIOD.

                        @mgrouch I don't have the slightest idea.
                        I run the apt update and apt upgrade to make sure I have the latest version.
