    In this chapter we describe how to program and erase the S110 nRF51822 SoftDevice or another application HEX file on the nRF51822 chip. If you want to start developing on the nRF51822 chip without using the S110 SoftDevice see Section 6.1.5 “Programming an application” on page 28.
  • Page 26 6.1.2 Identifying the nRF51822 chip and chip content When you select a board, nRFgo Studio identifies the nRF51822 chip and how its memory is organized. The following chip and memory information is displayed: • nRF51 chip identification - Identifies the chip by name and build code (for example, nRF51822 QFAACA).
  • Page 27 4. Set the SoftDevice size. This sets the size of the flash region 0 and will not be available if the size is defined by the HEX file. Note: The S110 nRF51822 SoftDevice can be downloaded from www.nordicsemi.com by logging into your MyPage account and entering the product key printed in the Development Kit.
  • Page 28 Evaluation Kit User Guide v1.2 6.1.5 Programming an application This function lets you program an application onto the chip. Before nRFgo Studio starts programming it verifies that the HEX file matches the actual memory configuration. If it matches, nRFgo Studio continues with the programming, if not it stops the programming and returns an error message.
