this is my /tftpboot tree

I tested the TFTP server is available, all files are available for download.

Where is the problem?

Hi @Jzhua​ 

I succeed to boot on tftp with the procedure.

content of my tftpboot directory ( I used artifact from defaut st-image-weston stm32mp1-disco image)

/tftboot :

menu title Select the boot mode

LABEL ramfs

KERNEL uImage

FDT stm32mp157c-dk2.dtb

APPEND rootwait rw earlyprintk console=ttyS3,115200

I need to remove line 'INITRD uInitrd' in order it works.

Problem looks to come from this broken line in your trace :

TFTP from server 192.168.1.94; our IP address is 192.168.1.2

'.lename 'uImage

On my side I got :

TFTP from server 10.xx.***.49; our IP address is 10.xx.***.120          

Filename 'uImage'.

Check for any syntax issue ?

Hope it help

The reason is default-arm-stm32mp file use CRLF not LF，now it work
