Target name in Makefile pca10028 for nrf51822

[phob]

Hi, I am using nrf51822 module and sdk v12.2.0. I was compiling code under ubuntu. I observed that pca10028 is configured for nrf51422_xxac target. But i want to use nrf51822. I check some document but i didn't get the proper target name to mention it in Makefile. Which target name i should use for nrf51822 module?

SDK 12 doesn't have examples for nrf51822. The pca10028 has more memory than the nrf51822, which makes it fail when using the build with a softdevice. I happened to be debugging this yesterday, and wrote a script to convert a pca10028 build to one for pca10001. It converts both the Keil/IAR projects and the Makefile: github.com/.../nrf-pca10028-to-pca10001

The main issue is not nRF51822 vs nRF51422

The nRF51822QFAC has 32kb RAM and the pca10028 BLE demo's work fine on that version of the nRF51822

The problem only occurs if you have a nRF51822QFAA (or potentially QFAB), as these only have 16k RAM

QFAB probably does not have enough room for the SD and an application, now that the only nRF51 SD in SDK12 is the S130 So if you have a QFAB you'd need to use an older SDK (possibly SDK 10) which still has the S110 SD as this will fit in the QFAB
