Hi everyone,

i have a problem with the gdbserver(old) in my uClinux-dist-2008R1.5-RC3 on my SRV1 Surveryor Robot (BF 537).

I want to use it in the serial way, like

gdbserver /dev/ttyBF1 ./test

and all i get is a flood of

Remote debugging using /dev/ttyBF1

readchar: Socket operation on non-socket

Remote side has terminated connection. GDBserver will reopen the connection.

It is the same problem mentioned here:

http://blackfin.uclinux.org/gf/project/toolchain/tracker/?action=TrackerItemEdit&tracker_item_id=3082

There it says it should be fixed,

but it isnt for me.

Am i using the wrong release candidate?

Thanks for your help!

Ah ok,

i did not see that, thank you!

Is it possible to just update the gdbserver in Clinux-dist-2008R1.5-RC3 from trunk,

or do i have to switch to the trunk version?

(as debugging is a critical task for me, that i dont want to miss)

Thanks in advance!

unfortunately, there have been other fixes/changes that require an updated gdb to work with the updated gdbserver, and perhaps an updated kernel as well

if you look at the Commits tab in that tracker item though, you should find the diffs that can be applied to the gdbserver in the uclinux-dist/user/... folder. hopefully that should be enough.

it worked!

i linked the /user/gdbserver directory of the trunk version into the /user/gdbserver directory of RC1.5.

(renamed /user/gdbserver first)

make - no errors - working on blackfin, great!

thanks for the help!
