Hi TI Team,
We could like to know if the firmware can be uploaded through Ethernet port when the device get connected to the network. We are using eMMC as a boot memory.

Hi Shwetha,
You can copy the firmware bundle using scp or any other means and run the attached scripts. You might need to perform slight modifications, but this script is a pointer for reference.
#!/bin/bash # To use this script first Flash your sd-card using #Create-sdcard script in SDK located in bin directory. #Then tar rootfs and copy the tarball in rootfs partition #of sd-card in any subdirectory.Copy this script to sd-card #and run it in the target machine using sd-card. #Enter yes if anything is prompted. cd / umount -f /dev/mmcblk1p1 umount -f /dev/mmcblk1p2 cat << EOM ============================================================================== Current partitions ============================================================================== EOM fdisk -l /dev/mmcblk1 cat << EOM ============================================================================== Removing all partitions ============================================================================== EOM echo "....WARNING...." echo "Continuing will Erase all the current data and Partitions in EMMC" CONTINUE=0 while [ $CONTINUE -eq 0 ] do read -p "Do You Want To Continue [y/n] : " CHOICE if [ $CHOICE = 'y' ] then CONTINUE=1 elif [ $CHOICE = 'n' ] then CONTINUE=-1 else echo "Wrong Choice...Enter y or n" CONTINUE=0 fi done if [ $CONTINUE = -1 ] then exit fi fdisk /dev/mmcblk1 << EEOF d 2 d w EEOF echo "" echo "All partitions removed." echo "" echo "" cat << EOM ============================================================================== Creating new partitions ============================================================================== EOM parted -s /dev/mmcblk1 mklabel msdos parted -s /dev/mmcblk1 unit cyl mkpart primary fat32 -- 0 9 parted -s /dev/mmcblk1 set 1 boot on parted -s /dev/mmcblk1 unit cyl mkpart primary ext2 -- 9 -2 cat << EOM ============================================================================== New partitions ============================================================================== EOM fdisk -l /dev/mmcblk1 mkfs.vfat -F 32 -n "boot" /dev/mmcblk1p1 mkfs.ext3 -L "rootfs" /dev/mmcblk1p2 sync sync if [ -d /temp1 ] then rm -rf temp1 fi mkdir temp1 cd temp1 mkdir boot mkdir rootfs mkdir temp rm -rf boot/* rm -rf rootfs/* mount -t vfat /dev/mmcblk1p1 boot/ mount -t ext3 /dev/mmcblk1p2 rootfs/ mount -t vfat /dev/mmcblk0p1 temp/ cat << EOM ============================================================================= COPYING U-BOOT ============================================================================= EOM cp -R temp/* boot/ echo "copying MLO" echo "copying u-boot" echo "copying uEnv.txt" echo "done.."

Hi Swetha,
One more pointer. You may not be able to update the linux partition, if already booted from eMMC and trying to update the same. What you can do is make A/B partitions for Linux and update it. Also make sure to modify the uEnv.txt in the boot partition to pick up the right updated partition
