FRDM-KW41Z OTAP client internal storage eeprom device internal flash

lschoenfeld — Wed, 08 May 2019 07:14:31 GMT

I try to use the FRDM-KW41Z with the BLE OTAP client example and configure it to use the internal Flash for temporary storing the image sent over the air (Kinetis Thread Stack Over-the-Air (OTA) Firmware Update User’s Guide, Chapter 3 Software implementation) and (BLEApplicationDevelopersGuide, Chapter11.7.2 The OTAP Client) . I can connect to the OTAP client using the IoT Toolbox. But when I start the upload the uploading stops at 9% and restart at 0% for several cycles. What can I do to get the OTAP client work with this configuration?

I am implementing the same with FRDM-KW36Z OTAP client internal storage eeprom device internal flash, and have the same issue. Firmware update restarts at 24 percent.

Also i found the progress bar of the Firmware update is fake, even if the device is switched/powered off the App still shows connected and the progress bar increases to the percent last shown and starts again.

NXP please update this and stop misleading us.

Hi Lothar,

Could you please try using the following document? It is intended for KW36 but it should work for KW41Z.

https://community.nxp.com/docs/DOC-342493

Hi Felipe,

the document describes the same thinks I did in KW41Z configuration. Sorry but that didn't help me. I tried to replace the Linker file. After building the application with the KW36 linker file I compare the memory configuration in the map file and I get totally confused. The Symbol _APP_START_ is 0x00000000 and __BootFlags_Start__ is 0x000020c0. How can this be? The Symbol gUseBootloaderLink_d is set to 1 in the MCUXpresso.

Second:

I tried to update the FRDM-KW41Z using the NXP Test Tool 12 with a FRDM-KW41Z Server module. In this case I can do the OTAP Update. So the problem isn't the configuration of the FRDM-KW41Z Client it is the iOS IoT OTAP application. Please be so kind and do some test bevor replay to my request.

Hi Lothar,

This issue has been confirmed as an error in the OTAP example when using internal flash. It has been reported internally so it can be fixed for next releases. Thanks for your comments.

Best regards,

Felipe

Hi Felipe,

what issue will be fixed? The OTAP IoT Toolbox problem, the map file or both?

Regards

Lothar

Re: FRDM-KW41Z OTAP client internal storage eeprom device internal flash

FelipeGarcia — Mon, 20 May 2019 14:32:33 GMT

Hi Lothar,

The internal team has confirmed Internal Flash Storage is currently not supported on KW41Z linker and bootloader. They will take a look into this, thanks for bringing this issue to our attention.

Best regards,

Felipe

Hi Felipe,

how long does it takt to get a solution? Sorry, but I'm a little bit under pressure.

hi , i m interrested in it too. does it mean ota can not work on kw41z please ? what are the news niw ? thanks a lot

Re: FRDM-KW41Z OTAP client internal storage eeprom device internal flash

lschoenfeld — Mon, 09 Sep 2019 07:43:10 GMT

Hi Florian,

in my project the OTAP works with the KW41Z now. I had to modify the memory layout for the KW41Z.

I’m able to do firmware update with the OTAP IoT Toolbox.

Regards

Lothar

Olfox — Mon, 09 Sep 2019 14:19:26 GMT

in one month an application note will be written to merge OTAP example into HRS demo code. I will do the job upfront. I already did on previous sdk. With the new there is few differences. I will upte all my tool and re do the job to start clean. then i will follow this first tutorial:

Reprogramming a FRDM-KW41 board using the OTAP Client Software

doo you have the samedi linker fiile than the one in USB sdk now ?Or something quiet similar ?

Re: FRDM-KW41Z OTAP client internal storage eeprom device internal flash

lschoenfeld — Mon, 09 Sep 2019 15:12:55 GMT

Hi,

I also started with an usb sdk and had to modify the linker file. The tutorial is helpful.

Regards.

Re: FRDM-KW41Z OTAP client internal storage eeprom device internal flash

Olfox — Tue, 10 Sep 2019 09:03:14 GMT

Lothar,

can you join your linker file please to see what as necessarry to change please ?

Thanks a lot it could be very helpfull if the tutorial is not enough :smileyhappy:

Thanks a lot Lothar !

I'm really surprised that it works fine becuse i compare your file and the one in USB sdk, and i have note some differences like :

___________________________________________

Lothar:

gUseBootloaderLink_d : 0;

USB SDK linker file:

gUseBootloaderLink_d : 1;

____________________________________________

Lothar:

gUseInternalStorageLink_d : 0;

USB SDK linker file:

gUseInternalStorageLink_d : 1;

____________________________________________

m_bootFlags_end = (m_bootFlags_start + 7);

m_bootFlags_end = (m_bootFlags_start + 16);

____________________________________________

/* #if gUseNVMLink_d && gEraseNVMLink_d */
/* .NVM : */
/* { */
/* FILL(0xFFFFFFFF); */
/* . = ORIGIN(NVM_region) + LENGTH(NVM_region) - 1; */
/* BYTE(0xFF) */
/* } > NVM_region */

should be linke this according to the tutorial:

.NVM :
{
FILL(0xFFFFFFFF);
. = ORIGIN(NVM_region) + LENGTH(NVM_region) - 1;
BYTE(0xFF)
} > NVM_region

but ORIGIN should stay and Lothar remove all.

So it seems that Lothar , you don't use the bootloader that is necessary to upgrade the firmware once downloaded and it seems you use external memory. Then how is it possible that you successfully use internal memory OTA feature please?

/* Workaround for SRAM boundary GCC placement issue,
not to place variables that are accessed by the code
overlapping this boundary (forbidden by the Kinetis architecture) */
__region_RAM1_start__ = (0x1FFF8000);
__region_RAM1_end__ = (0x1FFFFFFF);
__region_RAM2_start__ = (0x20000000);
__region_RAM2_end__ = (0x20017FFF);

That is a bit unsettling to see.

Variables would normally be aligned to a 16 or 32 bit boundary would they not?
So why would they cross that boundary?

I can see that a struct with the packed attribute could do it, anything else?

Hi!

I am implementing the reprogramming of a KW41Z board using the OTAP Client Software, with Internal Storage. Following the instructions of the link Reprogramming a FRDM-KW41 board using the OTAP Client Software

I got update the firmware using the otap_client_att as base and updating to the glucose sensor example. However the glucose sensor does not include the OTAP service so it is possible to reprogramming only once.

I tried to add the OTAP service to the glucose sensor example but I did not get succesfully. I copied the code of the OTAP service at otap_client_att following the document AN12775. The OTAP service requires OtaSupport.h and Eeprom.h. Selecting #define gEepromType_d gEepromDevice_InternalFlash_c and copying the MKW41Z512xxx4_connectivity.ld I achieved build without errors but the uploading does not start when I try to upload with the IoT Toolbox. It remains at 0%

Do you have any idea of the wrong proccess I am following?

Thanks and regards!
