    Hi Florian, PDK patches are under

    <PRU-ICSS-HSR-PRP-DAN_xx.xx.xx.xx_Path>\protocols\pdk_patches\04.03.00

    TI-RTOS PSDK 4.03.00.05 installs pdk_am335x_1_0_10. Please apply patches in PDK and rebuild PDK. Then rebuild PRU-ICSS HSR-PRP project.

    thank you,

    Paula

    Hi Paula,

    I don't know if I correctly install the PDK patches and I think no. Here are the files I have under PRU-ICSS-HSR-PRP-DAN_xx.xx.xx.xx_Path>\protocols\pdk_patches\04.03.00 :

    Fichier dispo sous pdk_patches.pdf

    Can you please explain me exactly what I've to do with that ? What is the procedure to apply the PDK patches ? The datasheet that I find on your website is not clear..

    Thanks.

    Best regards,

    Florian

    Hi Florian, from my C:\TI\PRU-ICSS-HSR-PRP-DAN_01.00.04.02\protocols\pdk_patches\04.03.00 I see there are two zip files (icss_emac and nimu_icss) also if you open PRSDK-3086-HSRPRP_2_interrupts_PDK.patch you can see only two files are actually patched 

    --- icss_emacDrv.h
    +++ icss_emacDrv.h

    ...

    --- src/icss_emacDrv.c
    +++ src/icss_emacDrv.c

    So I don't think you need to patch anything in "nimu_icss"...

    Some options:

    1) apply the patch inside. For patch.exe you need to input in command line the full path of the patch file, and the source dir (in this case something like: C:\TI\pdk_am335x_1_0_10\packages\ti\drv\icss_emac). After that, you need to rebuild PDK ICSS_EMAC driver, and rebuild your application

    2) After unzipping <PRU-ICSS-HSR_psth>\protocols\pdk_patches\04.03.00\icss_emac just replace the same folder inside PDK (C:\TI\pdk_am335x_1_0_10\packages\ti\drv\icss_emac). Again rebuild PDK, and app

    3) or just replace the two modified from <PRU-ICSS-HSR_psth>\protocols\pdk_patches\04.03.00\icss_ema  inside PDK emac =). Rebuild PDK and app

     

    How to rebuild PDK: 

    - In a command line window. cd to C:\TI\pdk_am335x_1_0_10\packages

    - Run  pdksetupenv.bat

    - then make: gmake clean, follow by gmake all... this takes for ever

    - to reduce time you can use instead gmake icss-emac_clean, and then gmake icss-emac

    More details here: http://processors.wiki.ti.com/index.php/Rebuilding_The_PDK

    Hope this helps,

    Paula

    Hello Paula,

    thanks for your help.

    Now that I have applied the patches, I find this error yet : " CortxA8: Unhandled ADP_Stopped exception 0x20023" ...

    What can I do to resolve this ?

    Thanks.

    Best regards,

    Florian

    Florian, sorry I somehow I missed your post.. are you still facing Unhandled ADP_Stopped exception? .. If so, my wild guess is that something is not completely right with how patches were applied.

    I will loop in this thread a colleague with more experience with HSR-PRP as well.

    thank you,

    Paula

    Florian,

    After you apply the icss_emac patch, did you rebuild icss_emac as well as nimu_icss library? Though there is no patch to nimu_icss, the library is dependent on icss_emac so has to be re-built. You may simply replace the icss_emac and nimu_icss with the ones from the .zip files in the pdk_patches\04.03.00 folder.

    Hello,

    Thank you very much for your help !

    After searching for the source of the error without success, I've juste uninstall and reinstall the CCS, the Processor SDK and the PRU ICSS SW for HSR/PRP.

    Now it works. I have the HSR application on my board.

    I don't understand where the problem was, but I think that the PDK patch was not installed properly.

    Thanks again.

    Best regards,

    Florian
