You don't need a /dev/env0. The EVB device tree has:
environment-sd {
compatible = "barebox,environment";
device-path = &environment_sd;
status = "disabled";
};
environment-emmc {
compatible = "barebox,environment";
device-path = &environment_emmc;
status = "disabled";
};
One of these nodes will be enabled based on the current bootsource:
if (bootsource == BOOTSOURCE_MMC && instance == 1)
of_device_enable_path("/chosen/environment-sd");
else
of_device_enable_path("/chosen/environment-emmc");
As you have exchanged the device tree you either don't have the nodes
in your device tree or the device tree doesn't match the board code:
The EVB board code has:
static const struct of_device_id rk3568_evb_of_match[] = {
{ .compatible = "rockchip,rk3568-evb1-v10" },
{ /* Sentinel */},
};
Which matches the EVB device tree:
compatible = "rockchip,rk3568-evb1-v10", "rockchip,rk3568";
I don't know exactly what you have changed and what not, but I think your
problem is somewhere here.
