TMDS64GPEVM: NFS boot

paras bhanot

Part Number: TMDS64GPEVM

i have been testing the new rootfs that we have compiled to perform NFS boot. I have set the following parameters regarding the IP address for both server and client (am64x soc ) in uBoot and i am able to ping the server successfully:

setenv ipaddr 10.16.83.100

setenv serverip 10.16.82.88

ping 10.16.83.100

nfs

However, NFS boot is stuck in loop after providing these commands. So we would like to know if there are any more parameters that we need to be set to get NFS working.

Also we would like to know if AM64x processor/Evm board supports Ethernet over USB for NFS (RNDIS support).

Hi Paras,
I'm attaching a PDF on flashing/booting eMMC on AM64x GP EVM.
The section "3 Booting Linux via UART Using NFS" in the PDF describes
- load kernel/dtb via TFTP
- mount rootfs via NFS
Hope it is helpful.
Best,

i have followed the step in given tn the PDF document still nfs boot is not working. i ran the following commands in uboot :

setenv ipaddr 10.16.83.100

setenv serverip 10.16.82.88

ping 10.16.83.100

setenv rootpath /mnt/nfs_boot

setenv bootargs console=${console} ${optargs} root=/dev/nfs nfsroot=${serverip}:${rootpath},nolock,v3 rw ip=${ipaddr}:::::eth0

but nothing works . It is still booting from sd card

Am i missing something ?

Hi Paras,
Can we capture the complete boot log from serial terminal, and upload it as an attachment?
