Increasing uboot size about nerves_system_rpi4 HOT 4 CLOSED

U-Boot size is also set here: https://github.com/nerves-project/nerves_system_rpi4/blob/main/rootfs_overlay/etc/fw_env.config#L9

If you're going to increase it, could you pick 128 KB (256 blocks in the fwup config)? The small size we have in Nerves is due to a mistake I made several years ago that we can't fix in a backwards compatible way. When we make major version bumps, I've been switching to 128 KB environment sizes.

We may need a bit more information. What exactly did you do to observe this? My initial suspicion is that you increased that variable, but tried an upgrade instead of complete task.

Sure, sorry about that.

I am trying to inscrease the uboot size by setting the following in fwup.conf

define(UBOOT_ENV_OFFSET, 16)
define(UBOOT_ENV_COUNT, 32)  # 16 KB

Then I run mix firmware and mix burn -t complete and in my rpi4 the following occur:

iex(1)> Nerves.Runtime.KV.get_all
%{
  "baudrate" => "115200",
  "bootcmd" => "bootp; setenv bootargs root=/dev/nfs nfsroot=${serverip}:${rootpath} ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}:${hostname}::off; bootm",
  "bootdelay" => "5"
}

I would expect that all my uboot env vars will be available (such as a.* vars and so on), but as one can see the envs are missing! An example should be

Nerves.Runtime.KV.get_all()
%{
  "a.nerves_fw_application_part0_devpath" => "/dev/mmcblk0p3",
  "a.nerves_fw_application_part0_fstype" => "f2fs",
  "a.nerves_fw_application_part0_target" => "/root",
  "a.nerves_fw_architecture" => "arm",
  "a.nerves_fw_author" => "The Octos Team",
  "a.nerves_fw_description" => "",
  "a.nerves_fw_misc" => "",
  "a.nerves_fw_platform" => "rpi4",
  "a.nerves_fw_product" => "box_nerves",
  "a.nerves_fw_uuid" => "c55c55ce-f333-525a-79f4-705df478b03b",
  "a.nerves_fw_vcs_identifier" => "",
  "a.nerves_fw_version" => "0.1.0",
  "nerves_fw_active" => "a",
  "nerves_fw_devpath" => "/dev/mmcblk0",
}

Thanks!

Thank you a lot. It worked as expected! 👍
