Hello, I am trying to boot kernel via TFTP from U-Boot on my DK2 board, after retrieving PXE configuration file successfully, the uImage failed to retrieved. However, I could successfully get uImage file by u-boot tftp command.
The steps I am following is https://wiki.st.com/stm32mpu/wiki/How_to_boot_the_kernel_via_TFTP_from_U-Boot#pxelinux.cfg_directory.
I have installed tftp servers on my Ubuntu, and the pxelinux.cfg directory, PXE configuration file, uImage, stm32mp157c-dk2.dtb are all under tftp directory.
/tftpboot
|---- mmc0_stm32mp157c-dk2.extlinux
| |--------- pxelinux.cfg
| |------------ 01-00-80-e1-42-51-72
| |--------- uImage
| |--------- stm32mp157c-dk2.dtb
my PXE configuration file is:
menu title Select the boot mode
DEFAULT sdcard
LABEL sdcard
KERNEL uImage
FDT stm32mp157c-dk2.dtb
APPEND root=/dev/mmcblk0p6 rootwait rw earlyprintk console=ttySTM0,115200
The TF-A, u-boot, uImage, dtb file are all released by ST.
The following is the u-boot log:
