Hi,

Let me talk about PRU-ICSS-PROFIBUS-SLAVEv1.00.01 for AM335.

My customer bought PROFIBUS Stack from TMG.
But it is not success to build.

We see this source file.

C:\ti\PRU-ICSS-Profibus_Slave_01.00.01.01\examples\profibus_slave\AM335x\AM335x_bsp.c

==================
g_pL2GlobVar->PruTxGpioNum =
5; /*pr1_pru0_pru_r30[5] is used as TX GPIO for PROFIBUS*/
g_pL2GlobVar->sel_GPO_GPIO = 0 ; /*PRUSS GPO for TX*/

g_pL2GlobVar->gpio_address = 0x0; /*Not used as PRUSS GPO is used for TX*/
g_pL2GlobVar->L3_mem_start_addr = SOC_PRU_ICSS_SHARED_RAM;
g_pL2GlobVar->pru_base_addr = SOC_PRU_ICSS_DATA_RAM0;
g_pL2GlobVar->edma_cc_base_addr = SOC_EDMA30CC_0_REGS;

/* Set in constant table C28 to ICSS Shared memory 0x10000 */
HWREG(SOC_PRU_ICSS_PRU0_CTRL_REG + CSL_ICSSPRUCTRL_CTPPR0) = 0x100;
HWREG(SOC_PRU_ICSS_PRU1_CTRL_REG + CSL_ICSSPRUCTRL_CTPPR0) = 0x100;
==================

We got error.
These are set value to the member variable of g_pL2GlobVar,
but this member variable does not exist in L2.h of the stack from TMG

Is this necessary for PROFIBUS communication ?
Can we remove ?

Hi Hiroyasu, let me check and come back to you.. by the way, which Profibus TMG stack version is your customer integrating?

Hi Hirayasu-san, I see g_pL2GlobVar inside the stack include folder (L2.h file) as an extern variable. A question, do you know if TMG gave your customer the stack with a sys_bios folder? (I guess they did, just to confirm).

extern TL2GlobVar XDATA *g_pL2GlobVar;

thank you,
Paula

Hi, Paula-san

Thaknk you for your reply.
We asked them.

Actually They used TMG stack for ISDK version 2.1.1.2.
and They do not get sys_bios folder.

I think they should ask TMG.
But If They can use L2.h in Processor SDK TMG stack for ISDK , Please let me know.

Best Regards
Hiroyasu

Hi Hiroyasu-san, yes please point them to TMG, that is the right approach.

thank you,

Hi,　Paula-san

TMG told them PSDK stack they provide is same as ISDK stack
and TI modify this ISDK stack for ProcessorSDK

If it is not true, I think Customer should ask again,
and get new stack for Processor SDK.

Hi, Paula-san

I made sure customer again,
So TMG told them TI should suggest for modify from ISDK to ProcessorSDK.
Let me know what we should chenge source code, if you know.

Best regards

Hi Hiroyasu-san,

From the developers, I got the information that we made some changes in the interface structure used between Stack and the application. Changes are mentioned here

Few more changes were done in structs names and file location, though..

About L2.h, you can point your customer to use it from our package (third_party\protocols\profibus_slave\include) in order to build both application and stack.

thank you,

Paula
