I get following error when I am trying to download the executable to lpcxpresso1549 board

02: Failed on connect: Ee(36). Could not connect to core.

System ist win7-64 bit

when i am doing the same with version lpcxpresso 7.2 build 153 everything works.
The same board under linux with version 7.3 works prefect.

downloading a executable to lpcxpresso1769 board works also perfect.

Whats the problem ?

OK. I *think* this is due to a bug in the CMSIS-DAP for that board and there is a new CMSIS-DAP image that is going to be released shortly that should fix this issue. In the meantime, please continue to use the Redlink image instead.

Yes I am able to confirm this with the installed CMSIS-DAP Image from the LPCLINK2 config tool it shows the error when version 7.3
ist used.

Can you confirm that the problem ONLY happens when CMSIS-DAP is running on the LPC1549 board. That is, it works correctly with Redlink V4_46.

The recovery doesn't help
When you look at the error you will recognize that with the on Board image CMSIS-DAP  flashing the target ist not working
with the image Redlink V4_46 loaded via dfu everything works.
when I use the older version of lpcxpresso IDE also no problem
On a second system with Os Ubuntu Linux and lpcxpresso version 7.3 the flash  button also works correct.

so it s no problem of the target mcu, I think its a problem of software talking to the link2 V2 part of the lpcxpresso1549 board.

From your description, it looks like you have put your target into a mode where the debugger cannot gain debug access to the chip.

This is described, with recovery instructions here:

Hello thanks for the answer.
First I did all steps you mentioned in your post.


Using the program flash button :

crt_emu_cm_redlink -flash-load-exec "E:\projekte\lpcv7\pnb1549\Debug\pnb1549.axf" -g -2 -vendor=NXP -
pLPC1549 -ConnectScript=LPC15RunBootRomConnect.scp -flash-driver=LPC15xx_256K.cfx

This is the error i get


Power cycle the lpc1549 board and attach JP3 before power connect.
In lpcxpresso IDE using Boot Debug Probe button results in loading firmware to RAM
with boot_link2.cmd i can verify that this is
      Booting LPC-Link2 with LPC432x_Redlink_V4_46.bin


after booting this image the use of Prgram Flash will show :

I also loaded with link2-config tool CMIS-DAP Software to the lpc1549 board the same results.

First of all make sure that you power down the probe when switching between different LPCXpresso IDE versions so that the probe firmware gets reloaded (the Redlink firmware from one version is not guaranteed to work with other versions).

Also make sure that there are no 'lingering processes running" - as detailed towards the bottom of :

http://www.lpcware.com/content/faq/lpcxpresso/booting-lpc-link2

Then please try powering up the board with the LPC1549 in ISP mode (press the ISP switch as you connect power/USB):

If you are still having problems, please post the debug log:
