Hi Padmalatha,

PADMALATHA GUDIPALLY said:

We are working on am335x based custom board. Trying to migrating the kernel 4.9 to 5.10,

Can you please confirm that kernel v4.9 runs on your custom board without any issue, but kernel 5.10 doesn't boot to Linux login prompt? 

what the board is boot from? sdcard or something else?

Hi Bin Liu

Thanks for reply. 

Yes , 4.9 kernel is working on our board with out any issue, but 5.10 doesn't  boot. 

Hi Bin Liu, 

Board is booting from MMC. 

 Hi TI team, 

We are trying to migrate kernel 4.9 to 5.10 from "systemd", I am attaching config file.

 Observations: 

1. When "CONFIG_NET =y" then kernel hangs as shown below,
