nrf51822 not detected

[guillermo]

Hello I have a nrf51822 mbed kit PCA 10024 V1.0.0. When I connect the kit to the PC (Windows 7 64 bits) the Mkit enumerates as an MSD named MBED:

I updated the firmware to version 2018following the instructions stated in the following link: developer.mbed.org/.../

After putting the binary file in the MSD, it dissapears and the mbed LED flashes continously.

Then I tried to get started openning nRFgo studio but the mbed kit is not detected (no boards connected).

Can anybody help me ?

Many thanks Guillermo

Can it be that the J-link driver is not present on the Segger chip anymore? Try to reprogram the J-link driver with the following steps:

• Download the J-link driver from the nrf51 product page.
• Enter bootloader mode on the Segger chip by keeping IF BOOT presset at startup
• Drag and drop the downloaded bin file, then do a power-cycle.

The board should now be visible in nrfGo studio. This question on developer.mbed.org might also be relevant to you.
