am57xx SPL with ethernet

Gennaro Tortone

Other Parts Discussed in Thread: AM5728

Hi,

I was wondering if it is possible (as with AM335x) for AM5728 to compile a SPL that support network fetch of u-boot.img;

I did it with AM335x adding to file include/configs/ti_am335x_common.h:

#define CONFIG_SPL_ETH_SUPPORT
#define CONFIG_SPL_NET_SUPPORT

but I did not have success with AM5728 applying the same recipe on include/configs/am57xx_evm.h

I'm using ti-u-boot-2016.05 with rcn patches

Thanks in advance,
Gennaro

Hi Gennaro,

Have a look at the following guide:
processors.wiki.ti.com/.../Linux_Core_U-Boot_User's_Guide

There are some additional env settings that may be needed.

Best Regards,
Yordan

Hi,
thanks a lot for your responsce;

I have already red TI U-Boot tutorial but I did not see any information to include network fetching of u-boot.img from a loaded SPL;

This was possible with AM335x recompling U-Boot including defines I reported...
but if I define them for AM57xx U-Boot did not compile... (to be more specific - SPL did not compile)

Regards,
Gennaro

Hi,

I am very sorry this is my mistake (I did not check the documentation).

See Table 33-9. Booting Devices Order in AM57xx TRM. The supported boot devices are:
USB
MMC/SD
eMMC
UART
SATA
QSPI
XIP/Fast XIP

The device itself does not support EMAC (Ethernet) boot.

Best Regards,
Yordan
