dfp path is not valid in ubuntu14.04 about csp

[djsaz]

Can you please show me the command you used to launch MHC? Do you see any red error messages saying a path is invalid?

[Kingders]

my command : java -jar ./mhc/mhc.jar -fw="/home/userA//MPLAB_XIDE/harmonyFrameworkv3" -mode=gui -c="/home/userA/MPLAB_XIDE/harmonyFrameworkv3/csp/apps/uart/uart_echo_interrupt/firmware/src/config/sam_a5d2_xult/harmony.prj"

then, come out a window called "Configuration database setup",
red error messages:" DFP path is not valid." in the bottom of the window
DFP ( auto-filled ) : ./dev_packs/Microchip/SAMA5D2_DFP/0.1.6/atdf/ATSAMA5D27.atdf
CMSIS ( auto-filled) ./dev_packs/arm/CMSIS/5.4.0
and the button "Launch" is GRAY, (mean disabled, can't click)

though, i change DFP CMSIS input in whole path !!
DFP: /home/userA/MPLAB_XIDE/harmonyFrameworkv3/dev_packs/Microchip/SAMA5D2_DFP/0.1.6/atdf/ATSAMA5D27.atdf
CMSIS : /home/userA/MPLAB_XIDE/harmonyFrameworkv3/dev_packs/arm/CMSIS/5.4.0
red error messages still be here
and the button "Launch" still be GRAY,

by the way, i run in ubuntu14.04 , and i just only be applied to use this machine , no other PC in window system can be used

Two things, 1) make sure you run the MHC that is in the /home/userA/MPLAB_XIDE/harmonyFrameworkv3/mhc directory. 2) You have to run mhc from the mhc directory. You can't run:
java -jar ./mhc/mhc.jar
You must cd to mhc then run:
java -jar ./mhc.jar

i know what you mean,

now my folder's tree like this:
$ ls harmonyFrameworkv3
audio bt core csp gfx micrium_ucos3 net touch wolfssl
bsp CMSIS-FreeRTOS crypto dev_packs gfx_apps mhc motor_control project usb

$ ls harmonyFrameworkv3/mhc
mhc .jar ......

then i run mhc.jar in folder mhc :
java -jar ./mhc.jar -fw="/home/userA/MPLAB_XIDE/harmonyFrameworkv3" -mode=gui -c="/home/userA/MPLAB_XIDE/harmonyFrameworkv3/csp/apps/uart/uart_echo_interrupt/firmware/src/config/sam_a5d2_xult/harmony.prj"

but not work, problem still exits

project just is my workfolder, not the one harmonyV3 provided

You need the trailing / in your fw path. It should be
-fw=/home/userA/MPLAB_XIDE/harmonyFrameworkv3/

[Kingders]

as you see
my command use trailing / always!!!
so these may not be the point causing this problem,,,,,,,

though, i tranfer
-fw="/home/userA/MPLAB_XIDE/harmonyFrameworkv3/"
to
-fw=/home/userA/MPLAB_XIDE/harmonyFrameworkv3/

problem still exits

With H3 downloaded and with the commands formatted as I've suggested, I am unable to reproduce what you're seeing. Would you be willing to do a webex meeting where I can see your screen and hopefully see what's missing?
