Kinetis FlexNVM

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 Haggui,

You are referring to the wrong post, about the MCUXpresso IDE, when you want to define some data in the defined flash range, please refer to the following post:

Relocating Code and Data Using the MCUXpresso IDE

This is what you are needed, you need to modify the linker file.

Wish it helps you!

If you still have question about it, please kindly let me know.

Have a great day,
Kerry

Hi Kerry,

Thank you for your quick response, maybe the thread I posted concerns the LPCXpresso IDE, however it contains the same steps as the thread you posted to me. The problem in fact came from the use of the FlexNVM as a PFlash. Thus when I add a section in the MCU setting that points to the FlexNVM region (@ 0x10000000 and LENGTH = 0x20000, alias Flash2), next using the cr_section_macros header file I define some data to be stored in this new region using __RODATA(Flash2). Everything seems to be OK until debugging, since i found that there is no data stored in the FlexNVM memory (it contains only 0xFFFFFFFF). My question, am I in need to specify a flash driver for the FlexNVM memory, as for the Pflash ? Moreover, am I in need to set the Flash Configuration block ?

Thank you.

Dear Haggui Souhail,

This is a known issue with MCUXpresso and projects using KW36. We will provide the fix in the public release of the KW35/36 device.

Your technical support person will be contacting you directly to provide the patch and the steps to support this because product has not been launched yet.

Best regards,

Miguel

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.

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)?

Re: Kinetis FlexNVM

hagguisouhail — Thu, 13 Sep 2018 20:26:03 GMT

Hi Miguel,

Yes that is it.

Re: Kinetis FlexNVM

miguel_reyes — Fri, 14 Sep 2018 00:07:47 GMT

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

We are waiting for their response.

Hi Miguel,

Any apdates please from Segger ?

Re: Kinetis FlexNVM

miguel_reyes — Fri, 21 Sep 2018 05:31:44 GMT

Hi Haggui,

The responded that they will be providing updates next week about when they would be able to fix this. I will let you know as soon as I get a response on this.

Thanks and 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,

Souhail

Re: Kinetis FlexNVM

miguel_reyes — Mon, 21 Jan 2019 17:34:32 GMT

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 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 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

Re: Kinetis FlexNVM

miguel_reyes — Mon, 28 Jan 2019 16:01:03 GMT

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 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
