Re: override alias in test application

Stefano Manni

Hi Carles,

thanks, I managed like this:

/ {
aliases {
eeprom_0 = &eeprom0;

but eeprom_0 is not a valid alias:

dtlib.DTError: /aliases: alias property name 'eeprom_0' should include
only characters from [0-9a-z-]

may I open an issue?

For properties there is /delete-property/ to delete one and then be able to override it.
In the case of an alias I am not sure, have you tried to override it directly?

Hi there,

I'm trying to compile test/drivers/eeprom for my board. I see that the
code requires the alias 'eeprom_0' defined, but my board does not have
it natively.

I managed to compile changing in the test app some lines like below:

- eeprom = device_get_binding(DT_LABEL(DT_ALIAS(eeprom_0)));
+ eeprom = device_get_binding(DT_LABEL(DT_NODELABEL(eeprom0)));

where eeprom0 is defined in an overlay for my boards.

But I'd prefer to use the alias and not change the app.
What is the right way to override an alias in an overlay file? Sorry
if my question is already addressed somewhere in documentation.

Another consideration: is 'eeprom_0' a valid name? Alias properties
should include only characters from [0-9a-z-]. May we need to fix it?
