Upgrade possible from nRF518220-EK?

A while ago, I purchased the nRF51822 Evaluation Kit, and this looks to be the exact same hardware, so I was wondering if it will be possible to update the firmware on the Segger chip to make it mbed-compatible. Thanks!

Question relating to:

The nRF51822-mKIT is a low cost ARM mbed enabled development board for Bluetooth® Smart designs with the nRF51822 SoC. The kit gives access to all GPIO pins via pin headers …

Hi, it's not the exact same hardware, updating the interface firmware on the SAM3U will not make it fully mbed-compatible.

What additional changes are there? If there's anything important, could it be done by modification of an existing board?

i was able to upload the mbed hex output to my EK as well as programming my EK using mbed code. I have not done any debugging however.

It's not so easy to see in the pictures, but the nRF51822-mKIT (PCA10024) has an ATMEL chip as the interface MCU and not a Segger. So I guess that is a no.

Except that the "Segger" chip, if you look at the schematic, is an ATSAM3U2CA-AU. Segger is really only responsible for the firmware, so the choice of chip does not preclude compatibility.

So many kit. I have successfully built the demo, trying to download to my kit.Anyway.

Hello,

I would also like to know if the NRF51822-DK or NRF51822-EK, which seems to be the same hardware, is compatible with the NRF51822-MKIT.

NRF51822-DK / EK ships with two boards, while NRF51822-MKIT with only one. Would this be the only difference?

Thanks

Hi , I have NRF51822 évaluation kit (1001), how can I CMSIS DAP apduten In m'y EK

I think the question is more of how to update the ATSAM3U2CA-AU to support CMSIS-DAP. In my EK, I have FW S110_nRF51822_6.0.0 in Region 0. if you could update it to support debugging, you probably will have everything the mbed kit could offer. You could use Nordic's lib or mbed stack for Bluetooth, compile it in mbed, flash the board using Nordic's studio. Did i miss anything here? other than debugging?
