Flashing application to BL653 via FTDI

[Vagner Landskron]

Hello,

I'm working with nRF52833/nRF82540 for quite a long and now we're starting to enter in production.

For this, we would like to flash applications using FTDI to a BL653-DK (Laird) for evaluation purposes.

According to what I've found in the internet, I should build and flash the Nordic's "MCUBoot", which I've done successfully (by adding "CONFIG_CLOCK_CONTROL_NRF_CALIBRATION_MAX_SKIP=0" to the prj.conf to the example bootloader\mcuboot\boot\zephyr).

Now I'm connecting the BL653-DK to USB-1 (FTDI) and trying to flash a "Hello World" application.

But I couldn't manage to make this device recognizable by any of the tools Nordic provides (west, nrfutil or mcumgr).

Any guess on what am I missing?

Thanks in advance!

Hello,

Is there a programmer on the DK that you are using? (I am not familiar with Lairds HW). If not, I believe that you need to program the bootloader before you are able to use it. The Nordic tools assume that you are using our HW, which has an onboard programmer. So if the Laird HW doesn't have that, you will not be able to use our tools with it. 

I suggest you check with Laird how you are supposed to interface the device without a programmer. Perhaps they have some custom tools that you can use.

Best regards,

Edvin

Hi Edvin, thanks for the feedback.
Just to update the status on this task. I think I've managed to perform it following this tutorial here:

https://lairdcp.github.io/guides/ble-gateway-firmware/1.0/docs/firmware_update

Mostly, what I had to do was to build the smp_svr + mcuboot as described here: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/samples/subsys/mgmt/mcumgr/smp_svr/README.html

Flash the "merged.hex" to the device.

And using mcumgr via serial I'm able to manage the images (flash, test and confirm).

There are still some issues to be mitigated, but they are more related to consumed flash memory and start-up time.

Thanks in advance
