nRF Cloud — CoAP transport (device shadow) Date of incident: 2026-06-22, ~13:04 UTC — still unresolved at 20:42 UTC (7h38m+) Device: nRF9151, modem firmware mfw_nrf91x1_2...
We are doing a DFU over BLE with the second MCUboot partition on an external flash. Some times Zephyr can't access the flash after booting, resulting in a bricked device,...
Hey, I am trying to implement ecdh key agreement and derivation, but I am getting PSA_ERROR_INVALID_ARGUMENT (-135) from psa_key_derivation_key_agreement: Any idea what is...
Hi,
I have a question regarding the SAADC timing parameters.
I could not find an official specification for the SAADC power-up time (t_PWRUP). While measuring it on my...
I am using nRF54L10 with nRF Connect SDK v3.1. The device connects over BLE, wakes every 30 minutes to read sensor data, and then should enter deep sleep (System OFF). However...
Hi all — I'm developing a custom nRF5340 development board (Raytac MDBT53-1M) and would value the community's honest read on whether it's worth producing.
The goal is...
Hi,
I am using nRF5340 (CPUAPP) with MCUboot and Partition Manager (pm_static.yml, CONFIG_PARTITION_MANAGER_ENABLED=y ).
Build and flash are successful, but during debug...
Dear Technical Support Team,
I have recently been developing with the nRF54L15-DK development board, using the official channel_sounding/cs_test example provided by Nordic...
I am designing a battery system with can charge or supply power via a USB-C PD controller. It will operate up to 20V. I want the option to connect this USB-C D+/D- to the...
Hello, I was able to flash the firmware built using the samples provided by the "nrf connect sdk" using VScode. But, I see failure when I tried to program the nRF54L15 with...
When the USB stack and your local Filesystem code both try to control the flash chip simultaneously, the system will crash or trigger a HardFault, causing the restart.
Dear Nordic,
I have a few questions I would like to ask.
1. I would like to inquire if there is an antenna pattern for the nRF54L15DK PCB.
I have already searched through...
I was trying to flash a program on nRF52833 development kit and got this error, it important to notice that my college was trying to flash (via VS code) it before and I am...
Hi,
I'm working with the nRF54LM20 DK (nRF54LM20A) and evaluating whether it can act as a USB host to read data from an external USB CDC ACM device.
The intended setup...
Hi
I remember the Devzonw could ask for hardware instructions. My matching circuir has used the nRF54L15 reference design and nRF21540 DK design, all the value is the same...
I used binwalk to analyze the zephyr.signed.encrypted.bin file generated by the routine mcuboot_with_encryption. I found that the firmware was not encrypted but merely compressed...
We have a peripheral device that maintains a PAwR sync (as a syncer/responder), connects to another peripheral in a central role, and also accepts connections from a central...
I tried writing read and write code for sEMMC based on information obtained from an AI assistant. The resulting code is shown below:
As you can see, the block address...
I used an oscilloscope to check the waveform and found that only the clock and IO0 had waveforms. I am using this interface to send data:
nrfx_err_t nrfx_qspi_write (...
This is just simple feedback on the nRF Connect Toolchain Manager v0.9.2.
The download speeds when installing an SDK are terribly slow. On a 1Gb /s connection my PC was...
