Hello,
I see that raspberry pi bootloader throws ton of warnings when supplied DTB file does not contain /__symbols__/ node.
On RPI 1B rev1 it looks like this:
dterror: no symbols found dterror: no symbols found dterror: no symbols found dterror: no symbols found dterror: no symbols found dterror: no symbols found dterror: no symbols found dterror: no symbols found dterror: no symbols found dterror: no symbols found
Do you have those errors with the default configuration? On a RPI 4, this only happens when setting uart_2ndstage to 1 in config.txt. According to the documentation, this option enables diagnostic information from the main firmware.
Yes, I have it with default configuration. And I really do not know why it is happening, I just described observations and that dtc -@ fixes this issue. Note that this is about 1b rev1 (the first revision); so the older HW, so maybe this can be a reason?
Unless this is different on RPI 1B, this means we are talking about a warning that happens when enabling diagnostic information, so I am not sure it warrants a change to stable kernels.
Well, that is why I asked, if it is something for stable or not.
