Kinetis FlexNVM

[hagguisouhail]

Has any one succeeded to configure the memory linker to use the flexnvm as a pflash, i tried with the example in the mcuxpresso section 14.3 Configuring projects to span multiple Flash Devices  (Configuring projects to span multiple flash devices  ), however the program doesnt work and it runs into the hardfault routine. I will be kindly thankful for any help plz.

Pleaze find attached an example that i am working with.

Best regards,

Hi Miguel,

After being able to split the .text memory section between PFlash and FlexNVM with the updated SDK, I am trying to run the OTA with the NXP Test tool. What I see is that I am able to do the OTA succesfully when the hole image is located on the Pflash section. However, since my project that I am building around the bluetooth_otac doesn't fit only on the PFlash, I was not able to run the NXP Test Tool which stucks each time I am selecting an Image file (*.bin or *.srec) that have been created from my project. Could you please help me with this issue ? Thank you.

Best regards,

Souhail

Hi hagguisouhail‌, 

We identified this issue after the software release. The current release doesn't support the FlexNVM when performing Over-The-Air upgrades. This example code is currently under development and it will be available in the upcoming maintenance release currently scheduled for December.

Sorry for the incovenience. 

Best regards,

Miguel

Hello Miguel,

I would like to know if there is any progress concerning the OTA with support for the FlexNVM because I really need this functionality.

Best reagards,

Hello hagguisouhail‌,

There is available the document Reprogramming a KW36 device using the OTAP Client Software, here is explained the FlexNVM storage functionality. I hope will useful for you. Let me know any questions about it.

Kind regards,

Edgar.

Hello hagguisouhail‌, 

This support is already included in our latest SDK. Pleaso, download the new SDK released on 10th January with Bluetooth stack version 1.3.4. This provides support for OTA using FlexNVM. 

You can download the new SDK through the "mcuxpresso.nxp.com" web page. 

Best regards,

Miguel

Hello Miguel,

I integrated the new SDK into our project, however I noticed that I am not able any more to debug the project. Notice that I am using Jlink from Segger. Even when trying with the LPC-Link v2 on which I programed the CMSIS (with lpcscrypt), I fail to flash the program on the kw36 mcu. Can you help me with this issue please.

Best raegrds,

Souhail

Hi Souhail, 

Could you please ellaborate more about what is the issue you are seeing? We recommend to use CMSIS-DAP. Could you please also confirm that you are using MCUXpresso 10.3? This is needed to use latest drivers to support FlexNVM. 

Regarding SEGGER support, there has been a delay. We expect to get new drivers in one month.

Best regards,

Miguel

Hi Miguel,

Allow me just to give you an overview to be more clear. We are working on a project that is based on the OTAP client example. Thus we have designed a new hardware based on mcu kw36 and we intend to program it via SWD JLINK or CMSIS-DAP. The first issue was the m_text memory exeecds the P-Flash section and you resolved that by adding the D-Flash section, with this modification we were able to program the kw36 only with the CMSIS-DAP interface of the LPC-Link v2, the Jlink didn't work with this modification and we were waiting for Segger to update their Jink driver. After that we have issue with OTA on two different memory bank, and you came up with one flash memory driver FTFE_2K_PD.cfx with the new SDK. I installed the new mcuxpresso 10.03 as you told me , before, I got the new software version of the LPC-Link v2 (Probe Firmware: LPC-LINK2 CMSIS-DAP V5.224) and I tried to flash the bootloader binary and otap application onto the kw36, Nevertheless I got an error and I am not able to resolve it.

I joined the error message that I got and here after you will find the consol log of the mcuxpresso.

Can you please verify with me this issue.

Hi Haggui

Did you try to perform a mass erase and unlock the chip before to program the OTAP bootloader?

Here are the steps to do it:

1-Change the OpenSDA firmware to J-Link version. Follow the steps in this post: FRDM-KW36: Update OpenSDA Firmware.

2-Open the J-Link Commander console. It is default located at C:\Program Files (x86)\SEGGER\<JLink_version>\JLink.exe

3-Type the command "connect". Then type "?" to select the device (MKW36Z512XXX4).

4-Select the SWD interface. Type "s". Then press "enter" again.

5-Type "erase" in the console. Then, type "unlock kinetis"

Hi hagguisouhail‌, 

We are looking into this issue. So, could you please let us know how did you programmed the bootloader binary? are you using the one from the latest release? 

Could you please use the JLink tool and see if you can connect with the KW36? I mean, run the JLink tool and be able to connect and unlock the device. Then, try to program a new application? We want to know if you are able to recover the part from the unknown state. 

Best regards,

Miguel 

[miguel_reyes]

Hi hagguisouhail‌, 

Could you please let us know if you still face issues on this? 

We are not able to reproduce the issue on our side. It would help if you can provide more details on the issue to investigate further. For example, check the reset line with an scope and see if device is reseting itself. Try to program the device using JLink instead of CMSIS-DAP. 

Please, let us know if there is any comment or question... 

Best regards,

Miguel 

[hagguisouhail]

Thank you Miguel.

[hagguisouhail]

Finally I have been able to program the the Dflash section with the new SDK and the CMSIS-DAP interface. Since our hardware uses the JLink SWD, I was not able to flash the software within our hardware neither on the FRDM-KW36 eval board. Can you check with me what is the problem please? thank you.

[miguel_reyes]

Hi hagguisouhail‌,

Let me check on this one. So, you are using MCUXpresso IDE with a Jlink interface to program your board and you are not able to program D-flash(FlexNVM)? 

[hagguisouhail]

Hi Miguel,

Yes that is it.

[miguel_reyes]

It seems SEGGER tools are not supporting FlexNVM programming. I already submitted a ticket to them. 

We are waiting for their response. 

[hagguisouhail]

Hi Miguel,

Any apdates please from Segger ?

[miguel_reyes]

Hello hagguisouhail‌, 

I know there has been a while since talked about this request. We just got an update from SEGGER that they integrated the support of the FlexNVM in their JLink beta version V6.47a. You could find the release in the next link:

https://www.segger.com/downloads/jlink/#J-LinkSoftwareAndDocumentationPackBeta

Using this beta software you should be able to flash the FlexNVM section of the KW36 device. 

Also, FRDM-KW36 OpenSDA SEGGER version was also updated. You could find it in the SEGGER web page. 

Best regards,

Miguel

Hello josem.reyes.chaidez‌,

kw36‌mcuxpresso 10.3.1 mcuxpresso ide and jlink segger jlink flexnvm 

Before the release of SEGEER JLink beta V6.47a, I have been programming KW36 FlexNVM with MCUXpresso IDE as mentioned in the below link:

https://community.nxp.com/docs/DOC-341634

Once after the program is compiled I used to download the code to KW36 using IAR Embedded workbench Download from file option using SEGEER JLink debugger.

Now once after the release of SEGEER JLink beta V6.47a, I could not able to modify the FlexNVM content which is previously written.

Can you share some detail steps to program or erase the KW36 FlexNVM using SEGGER JLink V6.47a using MCUXpresso IDE.

Thanks!

Regards,

Naven Suresh

[EdgarLomeli]

Hello nsuresh2@visteon.com‌,

There are the steps to update the J-Link drivers package in MCUXpresso IDE to handle the DFlash range address:

1. Ensure that you have updated the OpenSDA firmware with the newest version. Go to the J-Link web site, scroll down and search for the J-Link OpenSDA - Board Specific Firmwares. Download the newest firmware for the FRDM-KW36. Also, download the beta version of the J-Link Software and Documentation Pack.
2. Follow the steps described in this community post to update the OpenSDA firmware binary.
3. Update to the newest version of MCUXpresso IDE.
4. Open MCUXpresso, go to "Window -> Preferences". A new window will be shown. Go to "MCUXpresso IDE -> J-Link Options". Change the default JLinkGDBServerCL.exe path next to "J-Link Server executable text box", by the JLinkGDBServerCL.exe version included in the new beta pack that you have downloaded. The new path must be the following if you left the beta J-Link Software and Documentation Pack installation as default.
5. Try to program the device, and verify that the DFlash area is programmed or erased as you expect.

Please, tell us if this has solved your issue.

Best regards Naven.
