With the hard real time lxrt sem_clock example running, i.e. with a significant load, I've dowloaded tens of megabytes, at 4 Mbytes/s, many times, without any problem. Ciao, Paolo. Could you check also with a true ide disk?

Regards, Stuart I transfer to an ide disk. I have tried also to a ram disk and in this case all is fine. So the problem seems related to the simultaneous (interrupt?) activity of ethernet and ide driver.

[rtl] RE: RTAI1.3 and remote debugging
npace wrote: I am developing an embeddded application using RTAI.3/LXRT. I have either realtime user space process or realtime modules. Is there available a gdbserver / gdbstub to remotely debug (over a serial or TCP/IP connection) a user space realtime process or a realtime module ? Thanks Eng. Nicola Pace Hi Nicola, If you build gdbserver from the gdbsources (4.18 in the gdb/gdbserver sub-directory) that will work for userspace programs. For gdbstub, I have an (untested) version, this would need you to also use module offset loader to complete the serial line module debug capability. If you want them I will post them. Regards, Stuart I meant hard real time processes (those making a rt_make_hard_real_time() lxrt call), In this case if I attempt to use gdb/gdbserver the system crashes. Is anyone thinking to a gdbserver working also in this case ?
