RE: [ECOS] not able to connect to gdb with redboot

[Rajeev murthy]

dear Gary,
    i tried out the commands you have stated , but once i say tar remote /dev/ttyS0 the gdb hangs, never to come back. what must be the problem?
    i then connected the gdb to a hyperterm to see what it was sending , but it would send nothing. is there any changes required in gdb to be used with redboot? 
thanks a lot
rajeev

Just in case there is some problem with Insight, you could try using the
command line at least temporarily (run gdb with "-nw"). Have you chosen the
correct baud rate? For example if it is 38400, do this with "set remotebaud
38400" before the "target remote".

Use 'tar remote /dev/ttyS0' to connect via GDB.

Make sure that you disconnect from RedBoot (shutdown your minicom or hyperterm),
otherwise GDB will get confused.

If it still doesn't work, try:
  (gdb) set remotedebug 1
  (gdb) tar rem /dev/ttyS0

[ECOS] not able to connect to gdb with redboot

[Rajeev murthy]

hello,
   i have redboot on my board (a proprietory one with a Samsung microcontroller with an  ARM core). i understand that with redboot on my board i can get source level debugging by connecting to GDB via redboot.
   i am just not able to get GDB connect to my board. i tried all these things
1.target rdi /dev/ttyS0
2.target remote /dev/ttyS0
3.target rdp /dev/ttyS0
  what is the gdb looking for to connect ?
 i have set the baud rate to match my board's.
 is a serial connection with the host and the target board sufficient for gdb to connect with redboot on the board ?
  when i type $g#67 , i get a display of the registers which means the gdb stubs are working.
 but i would prefer to debug with insight.
please let me know where i'm going wrong and 
what i should do to connect to GDB?
  all inputs would be greatly appreciated.
thanks a lot
rajeev
