How to laod the yocto firmware on ConnectCore 93 using NFS

Hello,

i am trying to boot the ConnectCore 93 kit via the NFS .

i followed the instructions here:
https://www.digi.com/resources/documentation/digidocs/embedded/dey/4.0/cc93/yocto-boot-the-system_t.html

when i try to boot via NFS using command “dboot linux nfs”

it shows that it is loading but after that i get the error :

Filename ‘/exports/nfsroot-ccimx93_dvk/Image.gz–6.1-r0.0-ccimx93-dvk.bin’.
Load address: 0x84000000
Loading: T T T T T T T T T T T T T T T T T T T T T T T T T T T T T T
Retry count exceeded; starting again
Error loading firmware file to RAM

can anyone help me ?

this means there is a network connection issue between the board and the PC with NFS. Can you ping the IP of the PC from U-boot? Are the IP addresses of the PC and the address you assigned in U-boot in the same subnet? Does your PC run NFS server?
