Application hangs on SVC_HANDLER after ble_stack_init

[nagaraj]

Hi, I am using nrf51822 pca10004 with SDK110 v8 , I got a problem that the code hangs in sd_softdevice_enable and stuck in SVC_Handler.

Thanks, Nagaraj

Hi,

It could be that you have not set aside enough RAM for the SoftDevice.

What toolchain/IDE are you using?

NOTE:

As seen in this table, the nRF51x22 Evaluation Kit(PCA10004) uses an nRF51 IC revision 1 or 2. This is an outdated chip revision, and is not support in the newer SDK versions. As seen in this compatibility matrix, the newer SDK versions only supports nRF51 IC rev.3

I would therefore recommend upgrading to a Development Kit. For new products I would recommend a nRF52832-DK, where you have support for the latest SDK versions and Bluetooth 5.
