LPC4088 QSB + LPCXPRESSO V8.2.2 + LPCLINK2 error

[pascalreygner]

the LPC4088 QSB card is working correctly when using mbedCompiler (programming software / reset / soft working correctly).

when i connect EmbeddedArtists LPC4088 QSB Card + LPCXPRESSO V8.2.2 + LPCLINK2, the following failure appears on console debug message when trying connection with debugger : 

" LPCXpresso RedlinkMulti Driver v8.2 (Sep 5 2016 10:12:38 - crt_emu_cm_redlink build 725)
Found chip XML file in C:/Users/preyg/Documents/LPCXpresso_8.2.2_650/workspace/lwip_tcpecho_freertos/Debug/LPC4088.xml
Failed on connect: Ee(36). Could not connect to core.
No connection to emulator device ".

ERROR REPORTED BY TARGET : 

02: Failed on connect
Could not connect to core.
31: No connection to emulator device

i have tried proposed solution on this blog : Regaining debug access to target MCU 

using buttons SW1 + SW2 or changing  "vector cache", it is still don't work

DO YOU HAVE ANY SOLUTION?

thanks a lot

Please try the following..

1. Disconnect your LPC-Link2 and LPC4088 board from each other and from your PC.
2. Delete any .launch files contained inside your project directory.
3. Check that you have a jumper fitted on JP2 on your LPC-Link2 so that it provides power to the target (but leave JP1 with no jumper fitted so that the IDE can softload the probe firmware).
4. Now connect your LPC-Link2 to your LPC4088 using the 10 pin debug cable.
5. Now connect your LPC-Link2 to your PC - but do not connect USB from your PC to your LPC4088 board. (The LPC4088 board has a built in, but slower, debug probe as one of its two USB connectors - and we want to make sure that you are not driving the debug signals from both probes).

Now start a debug session for your project, and see what happens.

If you fail to get a debug connection still, please post the full debug log from the console view for us to look at...
