MIMXRT1050-EVKB flash fails

[juhhov]

Flash MIMXRT1050-EVKB board constantly fails. There seems to be two type of errors occurring. Daplink details.txt and full traces are attached.

Error number one: pyocd.probe.pydapaccess.dap_access_api.DAPAccessIntf.TransferError: No ACK received Error number two: pyocd.core.exceptions.DebugError: No cores were discovered!

@mmahadevan108 - can you look into this, please? This is a blocking issue for RaaS / CI. Attn: @maclobdell @MarceloSalazar - internal ref; IOTPART-8999

[mmahadevan108]

Release 254 does not have fixes that were uploaded to DAPLink repo in Nov 2019. Please see if you can get the latest from DAPLink master

[JanneKiiskila]

@mmahadevan108 - can you build the DAPLink? At least I'm not able to build it...

[mmahadevan108]

Below is the binary that I compiled k20dx_mimxrt1050_evk_hyper_if_crc_legacy_0x8000.zip

[danielRep]

Hi @mmahadevan108, do you mind to share the binary of DAPLink for Arm Musca-B1 ? Just to check if issue #802 can be solved , since I am not been able to build DAPLink master too. Thank you.

[mmahadevan108]

Hope this helps.

[maclobdell]

@JanneKiiskila - please confirm, is this resolved now?

[JanneKiiskila]

Tried with the attached image, unfortunately it still fails.

@mmahadevan108 - anything we can analyse further?

[JanneKiiskila]

USB mass storage mode works, though.

cp ./BUILD/MIMXRT1050_EVK/GCC_ARM/mbed-os-example-sockets.bin /media/jankii01/RT1050-EVK/ && sync

[JanneKiiskila]

Well, that was a bit premature. Actually, even the USB mode flashing fails now. FAIL.TXT says now:

error: The interface firmware FAILED to reset/halt the target MCU
type: target

So, the board is now stuck in a non-programmable mode.

Seems we have others with the same issue; https://os.mbed.com/forum/platform-317-MCIMX6RT1050-EVK-community/topic/33537

[mmahadevan108]

Can you share your DAPLink Details.TXT file.

[mmahadevan108]

Are you able to drag-n-drop a binary to the target? Below is a hello world binary. hello_world.zip

[mmahadevan108]

Prints hello world on the serial terminal, make sure baudrate is set to 115200.

[mmahadevan108]

I am not sure whats currently programmed to flash. I would recommend erasing flash via a debugger: Keil, IAR, MCUXpresso before trying to program.

[JanneKiiskila]

I had the mbed-os-example-sockets as the trial application. It worked once.

[JanneKiiskila]

Well, no change really here. Nothing on the serial, I think the actual flashing somehow fails? (as there is the FAIL.TXT in the USB drive). I don't think the FAIL.TXT should even appear on the drive, if the flashing works.

I deleted it and after copying the hello_world.bin to the device, it appears there again.

error: The interface firmware FAILED to reset/halt the target MCU

type: target

[mmahadevan108]

Can you please erase the flash contents and then try. I would suggest starting from an empty Flash.

[JanneKiiskila]

Not having much luck with that, either:

[mmahadevan108]

Suggest using a tool like Keil, IAR etc,

[JanneKiiskila]

It really should not matter WHAT is currently in the flash, IMHO. Whatever is there, should get overwritten by the DAPLINK application anyway (if you're flashing a .bin -file). So, we clearly have some underlying issue here at hand.

[mmahadevan108]

Sharing the below issue: https://github.com/ARMmbed/mbed-os/issues/12376

Hence I would suggest, erasing flash. I am not sure if there is something programmed to flash that keeps the platform continuously in deep-sleep mode.

[JanneKiiskila]

Well, I've now played with the KEIL MDK v5.29 and got the Flash menu activated. Tried erase there and well, I think it's still using the same underlying DAPLink, so no luck there either.

[JanneKiiskila]

So, I don't think we can progress anywhere until we get a better working DAPLink (or some other debug chip firmware). Is there an older, better working image available somewhere?

[mmahadevan108]

Please try setting switch to SW7 to OFF, ON, ON, ON. This will prevent the ROM from running the programmed binary. Then try erasing via Keil. Once erased, set SW7 back to OFF, ON, ON, OFF

[JanneKiiskila]

Should not the programmed binary at least try to print the starting statements? It's not printing out anything.

[mmahadevan108]

Hello World binary should print "Hello World" on the UART terminal and echo whatever you type.

[JanneKiiskila]

Error changes to "INVALID ROM TABLE" in Keil. It will not erase nor download the example.

[JanneKiiskila]

KEIL Flash settings.

[JanneKiiskila]

I downgraded the DAPLink firmware to the one available on the NXP website, I get a slightly different error to FAIL.TXT with that one;

The interface firmware FAILED to reset/halt the target MCU

But, still flashing fails.

244 had the wrong flashing algorithm and would not work for drag-n-drop. I am able to erase on my board via Keil. I don't see anything different in terms the settings you sent.

[jarlamsa]

The hello world application that @mmahadevan108 provided is working for me with the daplink he compiled. Flashing a larger binary to the board is very very slow now though.

[JanneKiiskila]

The official OpenSDA pages listed for this board are offering that, might be useful to update the official NXP offering for that?

Ref: https://www.nxp.com/design/microcontrollers-developer-resources/ides-for-kinetis-mcus/opensda-serial-and-debug-adapter:OPENSDA?&tid=vanOpenSDA#MIMXRT1050-EVK

Other ref doc;

https://community.nxp.com/docs/DOC-340156

mentions that I need to:

1. Configure the board for serial downloader mode by setting SW7 to OFF-ON-OFF-ON. 
2. Press SW3 to reset the processor.

Is that correct? I would claim it is not, since SW3 is the other user button. One should probably keep the SW4 pressed down, right? (Which seems to be the RESET).

[mmahadevan108]

OFF-ON-OFF-ON would be better than the one I sent. Yes, reset is SW4.

[JanneKiiskila]

With the OFF-ON-OFF-ON config the flashing seems to work, or at least there is no FAIL.TXT generated. However, the application does not seem to start or at least nothing comes out of the serial anymore.

• I've tried with the mbed-os-example-sockets (9600 baud) and the hello-world.bin (115200 baud).
• Both with the public DAPLink version and the custom one provided in this issue.

KEIL erasing does not work either, but with the OFF-ON-OFF-ON -config it at least tries, but does not succeed. KEIL flashing (aka upload) of hello_world.c also fails, to a timeout.

[JanneKiiskila]

Ok, so with some help from @jarlamsa - he changed the SW7 back to OFF, ON, ON, OFF and now it boots from the correct place and the SW runs. I didn't realize the OFF, ON, OFF, ON setup was supposed to be used temporarily. Hello world at least now runs correctly.

pyocd flash still does not work however.

pyocd flash ~/Downloads/hello_world.bin

It flashes successfully, but the app does not start again. In RaaS (test automation setup) we can't keep changing the SW7 modes.

If I then copy over (cp ~/Downloads/hello_world.bin /media/jankii01/RT1050-EVK/ && sync) it recovers and app starts again.

Flashing the bigger application (mbed-os-example-sockets) fails with pyocd flash, still.

So, we have some issue still.

After you have tried to copy over the mbed-os-example-sockets, board dies again. Even flashing the hello_world.bin does not seem to bring it back. Is the board allergic to bigger binaries?

Hello world is only 16 kB, while socket example is 143 kB.

[jarlamsa]

I don't have any problem flashing with drag & drop with the mbed-os-example-sockets, which toolchain are you using? Haven't tried with the pyOCD yet.

[JanneKiiskila]

Toolchain used is; gcc-arm-none-eabi-9-2019-q4-major

[jarlamsa]

I took a quick glance of the flash algorithms in the daplink-repo, they were changed in https://github.com/ARMmbed/DAPLink/commit/d33bff41de1f567c8504f97456e26271da5d46f9 I took the latest CMSIS-pack from Keil and noticed that the generated flash-algorithm for the hyperflash doesn't match the hyperhlash in the daplink but the spiflash instead. Were those mixed by accident somewhere? And what place has the wrong algorithms now? The pyocd-algorithms would need update also.

[jarlamsa]

@mmahadevan108 could you double-check the flash-algorithms?

[mmahadevan108]

I compared the flash blob that is is inside ARMmbed/DAPLink with the internal code base. I don't see a mistake, the file is for HyperFlash.

[jarlamsa]

Ok, thanks @mmahadevan108

Today we had a meeting to debug pyOCD on I.MXRT1050/2.

We tried two things. 1) Switch pyOCD to use the flash algo that is delivered with CMSIS pack

Steps to reproduce:

pyocd pack -i "*RT1052"

(wait to complete, ignore errors)

pyocd list -t -n rt1052 
pyocd flash -t mimxrt1052xxxxb "C:\Users\user\Downloads\mbed-os-example-blinky.MIMXRT1050_EVK.bin"

Result 1 Unfortunately, this fails for a known issue with the CMSIS pack for I.MXRT1052.

   pyocd.core.exceptions.TargetSupportError: No boot memory is defined for this device

Next we tried... 2) copy the flash algo from Daplink to pyOCD.

Steps to reproduce:

Install pyOCD from sources

git clone https://github.com/mbedmicro/pyocd  
cd pyocd
pip install -e . 

copy flash algo and pointers from: daplink/source/family/freescale/mimxrt1050_hyper_flash/flash_blob.c to: pyocd/target/builtin/target_MIMXRT1052xxxxB.py

then try to flash:

pyocd flash -t mimxrt1050_hyperflash "C:\Users\user\Downloads\mbed-os-example-blinky.MIMXRT1050_EVK.bin"

Result 2 This seems to fail in the same ways as previously.

pyocd.probe.pydapaccess.dap_access_api.DAPAccessIntf.TransferError: No ACK received

The board gets into a bad state and needs to be recovered using the SW7 switches and flashing with DAPLink Drag and Drop.

Actions - Ryan Chen from NXP has been contacted to debug pyOCD issues on I.MXRT105x.

I have ran all Mbed-OS tests on I.MXRT1050 using DAPLink drag-and-drop flashing (with the latest DAPLink binary provided by Mahesh) and testing with the Mbed OS master branch. This seems to be stable and working.

[juhhov]

838 seems to resolve the flash issue, thanks for that. Tested with head of master.

@maclobdell the erase however still seems to fail.

pyocd erase -vvv -u 0227000041114e45005d300ac207003692d1000097969900 -t mimxrt1050_hyperflash --pack NXP.MIMXRT1052_DFP.12.1.0.pack --chip

cc @jhqian (Big thanks for helping us finally make some real progress on the RT1052!)

@juhhov Thanks for testing. Basic flashing also works for me, and I similarly see an exception in some other cases. The failures may be due to not having code on the device. The "No ACK received" error means that the target is not responding to SWD at all. I'm going to look into it some more.

(Btw, you don't need to include the --pack argument in the command line since you are using the builtin mimxrt1050_hyperflash target type. The RT1052 pack also has some issues that prevent it from being used by pyOCD.)

Ive been working for 2 12+ hour days, trying to build images that can boot/burn into flash for my imxrt1050-evkb board. I can download existing images, using both drag and drop and MCUbootutility. Im missing something simple.
I would like the linker file and build settings for that hello world program, that is included above. I can drag and drop that onto my drive, and it is happily burned into flash. I want to know the settings/linker directives to create such a thing!!

[JanneKiiskila]

The trials were with Mbed OS, the Mbed OS linker files are in the folders available here: https://github.com/ARMmbed/mbed-os/tree/master/targets/TARGET_NXP/TARGET_MCUXpresso_MCUS/TARGET_MIMXRT1050/device

• separate folder for each tool chain (ARMC, GCCARM, IAR).

[ljfischer]

Thank you for the incredibly fast response - Im working in MCUXpresso - will attempt to convert this to that.

Strike that - I finally got the right combination of tools and settings. Thank you again for your help!
