Programming provision.hex of HomeKit on NRF54L15

[Sealin]

On NRF52840,  programming provision.hex with the command as follow:

%nrfjprog -f nrf52 --sectorerase --program  provision.hex --reset --verify

On NRF54l15, the nrfutil should be used. I tried with nrfutil, but it failed:

 % nrfutil device erase
️ Erased 150710859

% nrfutil device program --firmware merged.hex --options chip_erase_mode=ERASE_NONE
[00:00:04] ###### 100% [1/1 150710859] Programmed

% nrfutil device program --firmware provision.hex --options chip_erase_mode=ERASE_NONE
[00:00:00] ####-- 50% [1/1 150710859] Failed, [Probe] Device error: Missing programmer for memory=xip in Application
Error: One or more program tasks failed:
* 150710859: [Probe] Device error: Missing programmer for memory=xip in Application (Generic)

 

What should I do?

Thanks in advance!

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

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.

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.

% nrfjprog --memwr 0x00FFD080 --val 0x00000003

% 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!

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.
