Hi Segger,
I am using RTTClient to do firmware upgrades, and I noticed there is a big delay again on transmitting TCP packet on port 19021.
This has been discussed before:
[SOLVED] RTT slow not usable anymore
I can confirm that:
* JLinkExe V6.32a was FAST (~10ms delay on TCP transmit from port 19021)
* JLinkExe V6.46c is SLOW (~300ms delay on TCP transmit from port 19021)
* JLinkExe V6.44c fixed the issue again, and is FAST again (also documented in the thread mentioned above)
* JLinkExe V6.46e: REGRESSION! This version is SLOW again, with the ~300ms delay back in!
What exactly is happening? Is there a way we can control the TCP buffering behavior manually?
This makes upgrading JLink version difficult and requiring close monitoring and testing.
