it looks like MJ5 is using a hardware include for an older version of
the tiny (line212 of microjet5.xml)

replace that -DCONFIG=\"tiny.h\" with something compatible with your
version of the tiny
( maybe   -DCONFIG=\"tiny_2_1.h\" )

you can set what do you want on each UART ( GPS, telemetry) by
changing those lines your airframe file
( from microjet5.xml)

ap.srcs += downlink.c $(SRC_ARCH)/uart_hw.c datalink.c pprz_transport.c

ap.srcs += gps_ubx.c gps.c

here, you have telemetry/datalink on UART0 at 57600 and GPS on UART1 at 19200
