Part Number: TDA2P-ABZ
Tool/software: Linux
Hello Team,
Could you please help me customer with his uboot warnings?
My U-Boot port is now able to boot!
The kernel is booting, too.
But I got some problems to “smoothen” the boot:
There are three bad warnings, which comes along with a lot of debugging data.
Maybe the specialist can help me finding out, what is going wrong?
(Three “oops-ups” during processing the devicetree, I think and which are quite difficult to debug. May be your experts know something about them?)
