### TI CC26xxware out-of-tree
### TI_CC26XXWARE is the home directory of the cc26xxware
### It MUST be provided as a path relative to $(CONTIKI)
### For example, if
### CONTIKI = /home/user/contiki
### and TI_CC26XXWARE is stored in
### /home/user/cc26xxware
### then set
### TI_CC26XXWARE = ../cc26xxware

### also listed explicitly in the linker command (through TARGET_STARTFILES),
