Hi, I want to do an DFU OTA in nRF52840 BLE chip. I have flashed mcuboot bootloader and also flashed hci_uart (To scan BLE beacons) application. This will be one time flash using JTAG. Now, I want to

Hi Q1 – no, this mens that higher part of BLE stack runs on HCI client which has no access to nRF52840 flash at all. Q2 – mcuboot serial recovery or your proprietary protocol which can share common ua

Hello All, Right now I'm exploring the best way to do DFU OTA. I would like to ask that how i can do the DFU by booting the mcuboot bootloader in serial recovery mode. I have one nrf52840_pca10056 chi

Hello, I have nrf52840_pca10056 chip connected to imx6ul processor via uart (Both are embedded on my custom board) as shown in attached image. I'm using mcuboot bootloader on nrf52840 chip, now i want

Sorry for the earlier post. This always happens when I've been away from a platform during a major upgrade. I also had an overlay file redirecting spi0 pins that contained "status = "ok"". I successfu

Hi Jamie, You might want to take a look at how MCUboot invokes the reset vector in an NVIC table after having found the image: https://github.com/runtimeco/mcuboot/blob/master/boot/zephyr/main.c#L53 A

Hi There is a platform_whitelist in the sample.yaml file. In your case: "platform_whitelist: frdm_k64f " So you need this nxp board or have to port the sample to another board. Greetings Serafin

Hi. It looks that you have HFCLK running all the time. This is probably caused by small issue in power management code. Please try to remove the calls to nrf_power_task_trigger() from soc/arm/nordic_n

Hi all, I've ran some power consumption tests with Zephyr 1.12 #... a00646a5 Using the samples/boards/nrf52/pwr_mgr at lowest power mode, I find that the nrf52840 has a sleep current of ~550uA. When I

550uA usually means that the HFCLK is running. The HFCLK will run when something (peripheral) needs it. You need to find out what is using it, unfortunately neither the HW or the SW is able to tell yo
