About Nrf51422_1.0.0-2.alpha

Question

I get a nrf51422_1.0.0-2.alpha.zip. But why s310_nrf51422_1.0.0-2.alpha_softdevice.hex is bigger than 256K(287K),How can I burn this hex file into the nrf51422 Flash?

Beware that this zip is only to be used with second revision nRF51422s (not CA/C0). However, if you have such chips, you can flash the file using nRFgo Studio. 
 The Intel Hex format includes some checksumming and padding, and is an ASCII format, so it gives much bigger files than the actual binary content. This is not a prolem.
