Hi I'm using JEENI debug module wich supports semihosting (libc) on a
ARM7TDMI target. I'make use of function printf() from newlib wich seems
to work.
I've tried to execute  "printf("abc\n\n");" and I've logged the ADP
communication:
....

but no message are printed to gdb console. Are the above messages
correct?
Whath is the command to enable semihosting? Where GDB puts the receved
strings ?
