RTOS/AM3356: Profinet Slave v1.00.02 issue

Hi Garrett,

Thanks for the quick response.  

No I did not update the MLO,  

I just updated the MLO and tried --- it is now working as expected.   I guess I was thinking that the MLO was a "low level" boot loader that would not have changed between versions of the PDK.

Still not sure why I was getting the problem on load of the program into the debugger.   Hopefully you will find a similar easy answer!!

Regards,

Mark

Hi Garrett,

I am no longer concerned about the debugger issue I was having with the ICE board.    I started the port of the newest version and had no debugger load issues when loading onto my board.

I would like your recommendations on where to best disable one of the PHY's.     My functional requirement is that only one of two ETHERNET ports be active at a time,  and a jumper that is read during initialization determines which is active.      I was planning to isolate one of the PHY's based on the state of the jumper.   If I isolate one of the PHY's as part of the PN_socHwinit function that is called early in main() would that be the best place?       Other than the call to PH_configurePHYLed's in TaskPruss,   I am having a hard time finding if there is other PHY initialization and hence if that would be the appropriate place to isolate one of the PHY's.

Hi Mark, just to close the debugger issue. It is related to enabling DMTimer4 before loading the application. For your information DMTimer4 is configured inside am335x_app_arm.cfg .
In the case of using JTAG for loading the application, enabling DMTimer4 has to be done inside the GEL file. More details here: processors.wiki.ti.com/.../PRU_ICSS_Profinet

For your reference, I tested using below GEL changes (highlighted) :

C:\TI\ccsv7\ccs_base\emulation\boards\ice_am3359\gel\TMDXICE3359.gel

//****************************************************
//PRCM module definitions
//****************************************************
#define CM_PER_TIMER4_CLKCTRL (PRCM_BASE_ADDR + 0x88)
#define PRCM_MODULEMODE_ENABLE (2U)

hotmenu AM3359_ICE_Initialization()
{
GEL_TextOut("**** AM3359_ICE Initialization is in progress .......... \n","Output",1,1,1);
ARM_OPP100_Config();
//DDR2_EMIF_Config();
DDR3_EMIF_Config();

GEL_TextOut("Turning on EDMA... \n");
EdmaPrcm();
GEL_TextOut("EDMA is turned on... \n");
  
WR_MEM_32(CM_PER_TIMER4_CLKCTRL, PRCM_MODULEMODE_ENABLE);
GEL_TextOut("DMTIMER4 Enabled \n","Output",1,1,1);

GEL_TextOut("**** AM3359_ICE Initialization is Done ****************** \n\n\n","Output",1,1,1);
}

Hope this helps.
