Hi Stuart,

yes we all overlooked the pitfall that CC2538 belongs to the cc26xx family.
Can you please test with the last line of tcl/target/cc2538.cfg
changed to
      source [find target/ti_cc26xx.cfg]

I have no idea if CC2538 has any internal flash and if it will be 
properly handled by the new flash driver. The old config had no flash 
defined, so you should get the same functionality as before.
