GDB Remote Serial Protocol) http://sourceware.org/gdb/current/onlinedocs/ Appendix D. GDB Remote Serial Protocol http://sourceware.org/gdb/current/onlinedocs/gdb_34.html#SEC717 Okay. Easy, easy. Did you build any eCos test, eg, hal's 'basic' test for ROM startup? Does it work? What did you see in hypertem? If you did not try lightweigth eCos ROM applications, Do not dance with GDB/RedBoot! Try it in cygwin bash ecosconfig new <your_target_alias> minimal cat >fix.ecm << EOF cdl_component CYG_HAL_STARTUP { user_value ROM }; cdl_option CYGNUM_HAL_COMMON_INTERRUPTS_STACK_SIZE { user_value 4096 }; EOF ecosconfig import fix.ecm ecosconfig tree make -s && make -C hal/common/current tests arm-eabi-objcopy -O ihex install/tests/hal/common/current/tests/basic basic.hex You have to get basic.hex now to burn it in lpc ROM... Burn it, connect serial cable, run hyperterm (38400,n,8,1), reset board. What will you see? I thought about your port code. Is is alive? Next, get other tests in ihex format and try all them. All tests works for ROM startup? Only then go to GDB/RedBoot/stubs, etc. Sergei -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
