I was compiling a project(ble_app_uart and I am using PCA10028), it was not successful and KEIL5 display this:
it looks like I didn't install NordicSemiconductor.nRF_DeviceFamilyPack.8.11.1.pack according to the message (in fact, I already installed NordicSemiconductor.nRF_DeviceFamilyPack.8.15.0.pack). Then I downloaded NordicSemiconductor.nRF_DeviceFamilyPack.8.11.1.pack from KEIL and complied it again, it was still not successful, and KEIL5 display this:
it looks like 8.11.1 pack is not suitable for my board? how can I fix this problem? Thanks a lot!
