LPC54628: Error:Wire ack fault - target connected?

[jbhoi]

I am using LPC54628 kit. From debugging and programming image using LPC-Link debug probe. 

In PC, I have installed MCUexpresso to connect with the board via LPC-Link.

As a initial step tried "lpcxpresso54628_gpio_led_output" example to test but i couldn't able to flash to board. I can see below the error every time. 

In GUI of flash image configuration as below

Anything missing in above to select?

Note: JP5 jumper is shunted . USB cable connected to J1 for power supply and LPC-Link debugger attached. 

Does anyone have idea about how to resolve it?

any solution for this problem?, i have the board IMXRT1050, in MCUXpresso 11.3, and the latest version of sdk

Hi 

I tested LPCXpresso54628 demo board as below setting, no problem connect the board

I suggest you check below points:

0. make sure you use the latest MCUXpresso IDE version and latest SDK.

1. create a NEW project under a NEW workspace. test connection.

2. test the board with another computer.

3. update on board debug firmware with LPCScrypt.

LPCScrypt v2.1.1 | NXP 

Have a great day,

Thanks for your suggestion, I have tried all your points like updating LPC-Link2 debug firmware, new project and workspace, latest IDE (MCUXpresso IDE v11.1.1 [Build 3241] [2020-03-02]) and use of another computer but still no luck. See below setup 

[ZhangJennie]

Could you please try on board debug interface? It's J8 on board.

if can't connect with J8, shunt DFU to update the on board firmware, if CMSIS can't connect, try Segger

Thanks for your suggestions. First, I have tried by updating onboard firmware with CMSIS but using that still same error, see step by step process

then

then

So i have tried by updating segger, see below the process     

As console of MCUexpresso below prints come

if select the JTAG in GUI Flash tool then it continues in a loop or stuck at below menu

Also, I have below configuration for flash

we need to know if problem is for a specific project or a common issue for all project.

Please use default SDK helloworld demo code to test, can it connect board?

Hi ZhangJennie‌

Same problem with the default demo code of HelloWorld.

We have design a Microcontroller board with LPC55S06-JHI48EL. I am using the latest IDE MCUXpresso IDE v11.5.1 and other latest software from NPX. I am using MCU link to program the board. The MUC link firmware is updated with the latest software. MCU link is connected to PC through USB cable, Other end of MCU link is connected to my pin through 10 pin flat cable .I am getting the following above error. Please suggest a solution.

Please try if you can connect board in ISP mode?
