Today, I just get error when flashing (use Program Flash) and debugging. below is the error message:

I use: LPC812 Max Board, LPCXpresso v8.2.2 [Build 650] [2016-09-09] Software.

LPCXpresso RedlinkMulti Driver v8.2 (Sep  5 2016 10:12:38 - crt_emu_cm_redlink build 725)
Failed on connect: Ee(36). Could not connect to core.
No connection to emulator device.

Any advice? Last week ago, I have successfully debug or flash, I have try to change another usb port, change cable, restart pc, reinstall lpcxpresso. but sadly the problem still have.

Thanks.

In the first place, try powering your board up in ISP mode before trying to start your debug connection:

Thanks for your advice,

But the problem still not solved.

1. I have try install with another pc, but still fail

2. untick Window > Preferences > LPCXpresso > Redlink Options > Pull ISP on reset (on LPC-Link 2), but still fail

3. Add the script "ISPResetConnect.scp" to the "CMSIS-DAP Options - Connect Script" box within the dialog, but still fail

4. use lpc link2, jumper jip1 on lpc812 max, connect j7 (lpc link2) to p3(lpc812 max), but still fail

5. connect p0_1 (lpc max) to ground, reset, disconnect p0_1, but still fail

Any other step that I missed? or my lpc812 max is damage? hopefully not....

Pls see debug log:
