AM6442: CCS: unable to connect over CSS RSE to target

Stefan Mendel

Part Number: AM6442

Hello,

I use Code Composer Studio  Version: 10.3.0.00007 on Ubuntu 18.04 and if i try to get a ssh connection in CCS, i get the error "Algorithm negotiation fail". But if i open a terminal I can connect to the AM6442_EVM via SSH from terminal fine.

By side: to setup CCS i  followed the instructions from Processor SDK Linux 06_03_00_106 chapter  3.4.4.1 CCS Installation

Thank you for your support!

Best regards,

Stefan

    Hello Stefan,

    To confirm: Are you able to attach to AM64x cores following the steps here?

    Hello Nick,

    Thank you for your fast help.

    Okay step "4.4. Step 3: Setup CCS target configuration" works. The connection test has succeded.

    But i have troubles with the follwing step:

    I have installed mcu_plus_skd_am64x_07_03_00_19 on my Ubuntu host but i don't find PDK_INSTALL_DIR  on my host, neither in the sdk directory nor in the ti directory i can found the pdk.

    Where i can found PDK or can install it?

    PS: i also have installed mcu_plus_sdk_am64x_07_03_00_19 on my windows host and cannot found the pdk. 

    Best regards,

    Stefan

    In your MCU Plus SDK I would expect you to have a folder that looks something like pdk_am64x_07_02_01_11. That is your PDK directory.

    Keep in mind I'm a Linux guy looking at the legacy TI-RTOS section of the AM64x Processor SDK 7.2 download. The AM64x MCU Plus SDK 7.3 uses FreeRTOS instead, and may be organized differently.

    I am reassigning this thread to one of our RTOS focused team members. If you need additional assistance and have not heard back in a day or so, please ping the thread.

    Regards,

    Nick

    Hi Stefan,

    I'm a little confused, why are you looking for the PDK if you're using the MCU+ SDK? The MCU+ SDK is a replacement for the PDK and you should be using only the MCU+ SDK on AM64 going forward.

    Hello Stefan & Arnon,

    Apologies if I added any confusion. I was pointing to CCS steps for SDK 7.2. It looks like the SDK 7.3 MCU+ SDK documentation is in a different place (look for the "Documentation" section on the SDK download page: MCU-PLUS-SDK-AM64X_07.03.00.19 | TI.com ).

    The getting started steps for the SDK 7.3 MCU+ SDK (including setting up CCS) are here:

    Regards,
