AM4378: u-boot-spl : No ethernet found with Network boot.

Hi,

To enable debug if depends on the file in u-boot. Some files are setup to use printf, other files use a debug macro that is enabled on a per file basis. I have not done this in awhile so this is a suggestion, try adding this line at the top of the drivers/core/uclass.c file:

#define DEBUG

This should enable the debug macro that you see in the file.

The no ethernet found is coming from code in an area outside of what TI supports in u-boot. How are developing or porting the code? Did you start with the TI defconfig for example?

Best Regards,

Schuyler

Added #define DEBUG  in drivers/core/uclass.c file.But this not help.

Added some printf. uclass_find_first_device() is returning NULL, Not calling probe function.

SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ##

Currently This u-boot was ported for custom board based TI u-boot porting guide and EMMC boot was working(MLO,u-boot.img).

Hi,

I will review the porting guide to come up with additional suggestions. This will take a day or two.

Best Regards,

Schuyler

Any Update on this? 

I will try on am437x GP EVM and see what is the console output.

any update on this.

Hi,

After reviewing with the development team they are pointing out that there could be a missing commit in the version of u-boot that you are using. 

Please apply this commit 

To enable the config:
CONFIG_SPL_ETH_SUPPORT=y
in configs/am43xx_evm_defconfig

Best Regards,

Schuyler

This flag was already enable for the defconfig created for custom board.

Hi,

Would you be able to attach the device tree you are using?  We are checking to see if the ethernet was disabled. Could you also please share any changes to made to the source and also let us know which specific sdk version is used. 

Best Regards,

Schuyler
