Em::Blocks supports now the nRF51 devices from Nordic. You can select in the new project wizard which device family (51422 or 51822) and if soft devices are needed or not.
The templates for the softdevices are empty after first installation. The packages must be downloaded from the Nordic download section (after login) and unpacked inside the wizard template sub directories. After the execution of the convSD.bat file there will be c-array files and API includes generated which can be used by the wizard.
The softdevices are placed at the right location by the linker so you don't need other tools to pre-flash those devices.
After the wizard the debug configuration is automatically launched
EmBlocks is free downloadable at :
After installation one of the Softdevices (using convSD.bat script), ensure that memory layout provided by EmBlocks matches current Softdevice requirements.
For example, you can find the linker script of the newest S110 Softdevice, in our SDK: /examples/ble_peripheral/ble_app_hrs/pca10028/s110/armgcc/ble_app_hrs_gcc_nrf51.ld.
Using this information, you can readjust linker script from EmBlocks to the following one:
SOFTD (rx) : ORIGIN = 0x00000000, LENGTH = 0x18000
FLASH (rx) : ORIGIN = 0x00018000, LENGTH = 0x28000
RAM (rwx) : ORIGIN = 0x20002000, LENGTH = 0x6000
Similarly for the other Softdevices if need be.
Yes, currently only Windows is supported.
It seems that the default OS is still Windows and other OSes are mentioned explicitly like Keil, Attolic, IAR, etc etc.
But I have added the OS name at the top of the download.
One note, your website makes it really hard to tell what OS's you support! Doesn't look like the word "Windows" is mentioned anywhere on it, though that appears to be the only currently supported OS?
