Part Number: TDA2

Tool/software: Linux

Hi:   i am  use SDK_VISION_03_04_00_00

uenv.txt  is

fdtfile=dra7-evm-infoadas.dtb
args_mmc=setenv bootargs 'console=ttyO0,115200n8 vram=16M root=/dev/nfs rw nfsroot=172.17.218.22:/home/hancan/PROCESSOR_SDK_VISION_03_04_00_00/ti_components/os_tools/linux/targetfs rootwait ip=dhcp mem=1024M'

i  change  code of hlos  just  build  and reboot ,but  if  i  chage   code of  rtos  (for exmple   SDK_VISION_03_04_00_00\vision_sdk\apps\src\rtos\alg_plugins\framecopy\ frameCopyAlgoLocalDma.c  )   i  have  to  copy   firmware  of  C66  to sd   (  PROCESSOR_SDK_VISION_03_04_00_00/ti_components/os_tools/linux/targetfs/lib/firmware$       sudo cp dra7-* /media/hancan/rootfs/lib/firmware/  )

if  not  copy  the chage is not  done.   how  to solve  this ?

    Hi Shuai,

    If you use NFS as your filesystem instead of an file-system on the SD card, then you can set the LINUX_TARGETFS in build/tools_path.mk file to point to your filesystem. Similarly you need to use the uenv_nfs file present in build/hlos/scripts/linux/ folder and update the nfsroot variable to point to the IP address and the folder on your PC.

    If you're having the file-system on your SD card, then you must copy the firmware every-time.
