nrf6310 device firmware update is not working

[balaji]

Hi,

We are using nRF51822 evaluation kit. Actually we are trying to know how the device firmware upgrade is working. As mentioned in the nrf51 sdk manual, we did flashing the device firmware update application for nrf6310 to the pca10001, since we don't have sample code for pca10001.

Then following the readme file in the C:\Keil\ARM\Device\Nordic\nrf51822_v4.4.0.30888_Backup_1\Board\nrf6310\device_firmware_updates\experimental\ble_dfu_send_hex\readme.txt we installed,

a. IronPython v2.7.4 (2.7.3 in document) b. .Net Framework 4.5
c. Master Control Panel and Master Emulator API

Then connected the dongle and in the command window we entered the command as mentioned,

C:\Users\Public>ipy main.py -f ble_app_hrs.hex -n Embdes_HRM -a C52B0F4DF8E9 File main.py does not exist.

Then we gave the path of the main.py as follows,

[b]C:\Users\Public>ipy "C:\Program Files\IronPython 2.7\Lib\lib2to3\main.py" -f b e_app_hrs.hex -n Embdes_HRM -a C52B0F4DF8E9 Traceback (most recent call last): File "C:\Program Files\IronPython 2.7\Lib\lib2to3\main.py", line 14, in ValueError: Attempted relative import in non-package[/b]

so please tell how to overcome this, we need to know how the device firmware upgrade application is working on ble.

Regards, Balaji

Hi Balaji,

You need to run the main.py that included in "C:\Keil\ARM\Device\Nordic\nrf51822\Board\nrf6310\device_firmware_updates\experimental" not the one in C:\Program Files\IronPython 2.7\Lib\lib2to3\

You may need to install intelhex v1.5 plugin to make it work.

Thanks for your reply, i just did as you said, but now the error i am facing is

Have you installed the latest version of Master Control Panel ? www.nordicsemi.com/.../nRF51822-Development-Kit If should be installed here C:\Program Files (x86)\Nordic Semiconductor\Master Emulator. You should also not run Master Control Panel when you start the bootloader software.

[balaji]

Master control Panel is installed in the following path in my machine, C:\Program Files\Nordic Semiconductor\Master Emulator\2.1.6.8098

Is this fine ?

Hi Balaji,

Have you tried to reinstall Master Control Panel ? If you already did, could you try to create the C:\Program Files (x86)\Nordic Semiconductor\Master Emulator folder and put the 2.1.6.8098 inside ?
