16: Target error from status-poll 16: Target error from status-poll Wire ACK Wait in DAP access

[zhongshen]

I update my system from ubuntu 14.04 to 18.04. And re-download MCUXpresso IDE from NXP web. And I build  a sample program from SDK for RT1050-EVK, and debug it on the RT1050. The download axf to the target is fine, the debug window show to step to main, when I click one step, I got the error as following, and it can not back to the debug windows and untill I force to end the arm-none-eabi-gdb process!

16: Target error from status-poll
16: Target error from status-poll
Wire ACK Wait in DAP access
Debugging context: evkmimxrt1050_pit LinkServer Debug

And I reduced the wire speed to 1000000 HZ, according to the 16: Target error from status-poll: Ee(02). Not connected to emulator , but the problem still exist. Please advise me how to solve this problem.

Thanks.

[lpcxpresso_supp · Accepted solution]

If you are wanting to debug an image running from RAM rather than flash, then it might be worth doing a mass erase of the flash to ensure that no code that has been previously loaded into flash is executed before you execute code downloaded into RAM. You can do this using the IDE's GUI Flash Tool (described in chapter 13 of the MCUXpresso IDE v10.2 User Guide).

Aside. Please be aware that the current SDK version is 2.4 (rather than the 2.3.0 version you are using). It might be worth you downloading the new version and replacing your currently installed package.

I have updated SDK2.4.1 for EVKB-IMXRT1050. The debug problem fixed.

Thank you！

[lpcxpresso_supp]

Can you please post the text from the "Debug messages",  "RedlinkServer" and "gdb traces" logs from the Console view from after you see this problem. See section 18.8, "The Console View", of the MCUXpresso IDE v10.2 User Guide for details of how to do this.

Can you also confirm the exact SDK package and version you are using (as shown in the "Installed SDKs" view), and whether you are debugging your application running from Flash or from RAM (in which case, which block)?

Regards,

MCUXpresso IDE Support

SDK version is 2.3.0. As it is sample from SDK and do not have any change in the project files, the application is debugged, which running in the RAM. And the content of evkmimxrt1050_pit_Debug_memory.ld is following:

[zhongshen]

And when I changed the project properties to unchecked the Link application to RAM, which means to run application in Flash, the debug works well. Is it the problem to run in the RAM? 

[zhongshen]

Thank you for the reply.

Infact, before upgrade system this board works well with MCUXpresso IDE and SDK sample code. The ide version is the same, only difference is Ubuntu version: 14.04 vs 18.04.

And I confirmed that the there is not any other debug session running in it. Any way I used “Clean up debug” button, then debug the program again, the problem still exist.

[lpcxpresso_supp]

We've tried replicating your environment here using Ubuntu 18.04 and some example projects (both led_blinky and pit (which I think you are using)) from the RT1050 SDK with a rev 3 MIMXRT1050-EVK development board.

Initially we did find a similar problem, but it was due to out of date firmware in our board.  Once this was corrected we had no problem running either example.

The symptom your example shows normally occurs when the development board is so upset that it takes away access to the main debug access port (for a debugger - a catastrophic event).  The RT1050 and the above development board do present the user with quite a large number of subtle variables that can change to give symptoms like this.  It's certainly well worth while going through the document described above:

If you still have problems, the next step would be to go through : Overview of using the MIMXRT1050-EVK with MCUXpresso IDE 

very carefully.

Your example is interesting insofar as quite a lot of complex debug behaviour has been successfully negotiated in order to get you to the breakpoint on main() (which you do seem to have reached).  Basically, quite a lot is working!  You've run the project and the problem is then signalled asynchronously as the debugger is polling the debug interface to spot when it enters debug state.  Such problems are usually either temporary (the debug port is still usable) or permanent (almost nothing except reset will restore the debug port).

It's difficult to think of anything active at this stage which has not operated correctly already and which is also operating system specific.  (That is, it will be difficult to find a change between Ubuntu 14.04 and 18.04 that could be to blame.)

Although some might regard it as poor MCU design (and some not) the RT1050 is prone to escalating some basic errors (such as accessing bad addresses) to this level (e.g. by hanging the debug bus).  It is likely that the processor has encountered some problem like this.

Occasionally we see the effects of the last run of code (stored in, then booted from flash) leave a harmful legacy that (e.g. watchdog timers) is inherited.  There are a number of ways around this, but you might like to erase your flash before booting: If you then find that the first run is OK but subsequent ones are not, this is a sign that you have this class of problem.

Hi

Thank you for the reply. 

Do you mean that my board firmware is out of date?

My RT1050-EVK firmware information is following:

# DAPLink Firmware - see https://mbed.com/daplink
Unique ID: 0227000041114e450057300cc40300465ab1000097969900
HIC ID: 97969900
Auto Reset: 0
Automation allowed: 0
Overflow detection: 0
Daplink Mode: Interface
Interface Version: 0244
Bootloader Version: 0242
Git SHA: 853df431d81359e822f49363891f877f17d31efb
Local Mods: 0
USB Interfaces: MSD, CDC, HID
Bootloader CRC: 0x73707d49
Interface CRC: 0x565000e7

Do I need to update firmware from the link OpenSDA Serial and Debug Adapter|NXP ? But I see the latest firmware version is 0244 that is same as my board.

Any way I update firmware on RT1050_EVK, the problem is still existed.

And I have used my old PC with Ubuntu 14.04, the same MCUXpresso IDE with this RT1050_EVK, there is not any problem to debug the same sample project.

 And with new PC with Ubuntu 18.04 for more detial, I found that the problem was token place after writing the IO register as following code:

LED_INIT();   // -->  USER_LED_INIT(LOGIC_LED_OFF) ---> GPIO_PinWrite(BOARD_USER_LED_GPIO, BOARD_USER_LED_GPIO_PIN, output);

void GPIO_PinWrite(GPIO_Type* base, uint32_t pin, uint8_t output)
{
   assert(pin < 32);
   if (output == 0U)
{
   base->DR &= ~(1U << pin); /* Set pin output to low level.*/
}
else
{
   base->DR |= (1U << pin); /* Set pin output to high level.*/
}
}

When executed base->DR |= (1U << pin); /* Set pin output to high level.*/, the debug is stop on "16: Target error from status-poll".

Before executing base->DR |= (1U << pin); /* Set pin output to high level.*/, I try to read register there is still a problem as following to stop the debug:

Is my pc too faster so that it can not read back from the board?

And I only use my slow pc for the development on MCUXpresso IDE :smileysad:

First of all before you try debugging again, ensure that there are no debug executables still running (that may have hung). The easiest way to do this in MCUXpresso IDE v10.2.0 is to use the "Clean up Debug" button on the toolbar.  "Clean up debug" will kill all debug processes associated with LinkServer, P&E and SEGGER debug connections. This button can be used in the event of a debugging crash to remove any failed processes that remain. Note: a warning will be issued with the option to cancel before any action is performed since this action will kill all connected debug sessions. 

Then ensure that you have powered your board off and back on again.

Then delete any launch configurations inside your project.

[ Note that the notes regarding wirespeed in the old LPCXpresso IDE FAQ you refer to is not applicable to connections made in MCUXpresso IDE via LinkServer debug connections.]

Now try starting your debug connection again.

If you still have problems, the next step would be to go through : Overview of using the MIMXRT1050-EVK with MCUXpresso IDE 

If you need further assistance, please can you also confirm if you have ever successfully debugged this board?
