Hi,

The HomeKit support in NCS has been deprecated, as announced in the nRF Connect SDK v2.5.0 Release Notes. Hence, there is no nRF54L15 support for HomeKit in NCS.

Thanks for replying again.

I upgraded the nrfjprog, then it works. But the provision programming was still failed.

% nrfjprog -v
nrfjprog version: 10.24.2 external
JLinkARM.dll version: 7.94e
% nrfjprog --recover
Recovering device. This operation might take 30s.
Erasing user code and UICR flash areas.
% nrfjprog --memwr 0x00FFD080 --val 0x00000003
Parsing parameters.
Writing.
% nrfjprog --program '/Users/sealinzhang/Downloads/provision_02J5_316-63-627.hex' --chiperase --verify -r --log
[error] [ Client] - Encountered error -173: Command erase_file executed for 3101 milliseconds with result -173
[error] [ Worker] - Address range [0x10001080 - 0x10001087] does not map to a known memory.
ERROR: The file specified is not a valid hex file, has data outside valid areas
ERROR: or does not have data in valid areas.

The reason for the error should be that this provision.hex does not match NRF54l15.

I will get the new one.

Thank you!

Thanks for your help.

I upgraded the nrfjprog, then it works when I use "nrfjprog --memwr".

But the provision.hex I get from Apple Server is not matched with NRF54l15.

I got it before for the NRF52840 with follow configuration:

"NRF52840": {

"family": "NRF52",

"flash_size": "0x100000",

"settings_base": "0xfe000",

"settings_size": "0x2000",

"device_id_reg": "0x10000060",

"uicr_eui_reg": "0x10001080"

}

0x10001080 is the CUSTOMER[0] of NRF52840's UICR.

But thers is no CUSTOMER[] in NRF54l15's UICR.

What should I set the uicr_eui_reg for NRF54l15?

"NRF54L15": {

"family": "NRF54L",

"flash_size": "0x17d000",

"settings_base": "0x179000",

"settings_size": "0x4000",

"device_id_reg": "0x00FFC304",

"uicr_eui_reg": "?"

}

BR.

Please try to update the nRF Command line tool to the latest version and use the Programmer app in nRF Connect for Desktop.

Works for me; the nrfjprog version matters, needs a newer version see current version with "nrfjprog -v":

nrfjprog -v
   nrfjprog version: 10.24.2 external
   jLinkARM.dll version: 7.94e

Thanks for replying. I tried the sequence.

% nrfjprog --recover
Recovering device. This operation might take 30s.
Erasing user code and UICR flash areas.
% nrfjprog --memwr 0x00FFD080 --val 0x00000003
[error] [ Client] - Encountered error -90: Command read_memory_descriptors executed for 12 milliseconds with result -90
[error] [ Worker] - Can't read memory descriptors, ap-protection is enabled.
ERROR: The operation attempted is unavailable due to readback protection in
ERROR: your device. Please use --recover to unlock the device.
NOTE: For additional output, try running again with logging enabled (--log).
NOTE: Any generated log error messages will be displayed.

Maybe I should use nrfutil. nrfutil is the programming solution for nRF54l15. nrfjprog is no longer used for programming on it.

But I didn't find the similar command of nrfutil as "nrfjprog --memwr".

BR.

Is this any help? IAR v9.40 doesn't program the nrf54L15, so I use this sequence:

// nrf54L15 UICR Arm Cortex-M33
// ============================
// To program a hex file:
// In .\nRF5_SDK_17.1.0_ddde560\examples\peripheral\blinky\pca10156\blank\iar\_build
//  nrfjprog -v
//    nrfjprog version: 10.24.2 external
//    JLinkARM.dll version: 7.94e
//  nrfjprog --recover
//  nrfjprog --memwr 0x00FFD080 --val 0x00000003
//  nrfjprog --program blinky_pca10156.hex --chiperase --verify -r --log

Hi,

Thanks for replying.

I'm using NCS V2.9.0.

The provision.hex is got from Apple Server. It includes Setup Code and an initial token.

Homekit uses the follow code to get the data :

err = settings_subsys_init();

// Register event handler with FDS.

err = settings_register(&HAPPlatform_settings);

...

err = settings_load();

So, should I program it to the settings_storage ?

The settings_storage is set in pm_static.yml as follow:

settings_storage:

address: 0x179000

region: flash_primary

size: 0x4000

BR.

Hi,

Which NCS version are you using?

How do you get/generate the provision.hex?

Are you programming the provision.hex to external memory for nRF54L?
