2. i want to change kernel configurations and need to add as patch, i will change tisdk_am64xx-evm_defconfig this file,not able to add as patch,it does not show the changes i have made.

Please share you valuable inputs expecting early reply

Thank you

There has been a side channel email discussion, in which it looks like you are trying to use ICSSG from uboot (CPSW was used succesfully before). We don't support ICSSG from uboot, is there a reason you switched to using ICSSG? Hopefully you are using RGMII2, so this would just be:

A further note the low end AM6412 does not support Ethernet from the ICSSG. See datasheet https://www.ti.com/document-viewer/AM6442/datasheet/GUID-FFD00728-219F-4EA1-86E5-CFD88D0A626B#TITLE-SPRSP56TOCWRAPPER_DEVICE_COMPARISON column for AM6412.

Hi,

TI will not be able to support debug of external drivers that cause the kernel to hang during boot. Since this is a new board have you tried booting without making any kernel config changes? I am assuming here that the kernel config was modified.

Best Regards,

Schuyler
