newbie having problem with nrf51822, s130 and Keil

[talha]

Hi,

I am trying to run an example project which includes a softdevice using Keil uVision on nrf51822xxAA. What should I change in Options for Target? Especially what should be the Target ROM and RAM areas for softdevice and main program?

My HF crystal is 16.0 MHz and I am using JLink for debugger, I have already changed those areas.

Then you have 256 kB of flash and 16 kB of RAM. The SDK 11 examples are setup for 256 kB of flash and 32 kB of RAM.

So in general you should only need to reduce the size of IRAM1 by 0x4000.

So for example in the ble_app_beacon example you have 0x6790. This should be reduced to 0x2790.

Please be aware that some of the examples require more RAM than you have available with 16 kB.
